Definitions
- the invention relates to a tool for roughening a borehole surface, comprising a coupling portion for clamping the tool in a drilling tool and a tool head for machining the borehole surface, wherein the coupling portion (12) at a first end of a tool shank (16) and the tool head (14) an opposite, second end of the tool shank (16) is arranged and being provided on the tool head circumferentially arranged cutting means.
- the mortar composition in the cured state cooperates with the borehole wall in a form-fitting manner. This can be achieved by at least part of the borehole wall being roughened by machine or provided with a profiling.
- Tools and methods for roughening a borehole surface of the type mentioned above therefore serve in particular to increase the carrying capacity of chemical mortar compositions in diamond-drilled holes.
- the comparatively smooth inner circumferential surface of a borehole is structured and provided, for example, with defined undercuts.
- DE 31 43 462 A1 and DE 38 19 650 A1 each describe tools on the tool shank of which a conical or crowned contact surface is provided, which enables a user to manually superimpose a wobbling motion on the tool rotation. In this way, the tool head is deflected in the radial direction and penetrates into the borehole surface.
- DE 196 10 442 A1 proposes an asymmetrical arrangement of the tool cutting edges, so that the tool has an imbalance which generates a tumbling motion during drilling operation.
- the present invention is based on the technical problem to provide a tool for roughening a borehole surface, which the the disadvantages described above, or at least to a lesser extent and in particular reliably allows the roughening of a borehole surface, wherein the influence of the user is minimized and at the same time the ease of use is increased.
- a tool for roughening a borehole surface comprising a coupling portion for clamping the tool in a drill and a tool head for machining the borehole surface, wherein the coupling portion at a first end of a tool shaft and the tool head at an opposite, second End of the tool shaft is arranged and being provided on the tool head circumferentially arranged cutting means.
- the tool head has at least one laterally continuous slot which, starting from an end face of the tool head, extends axially along a tool longitudinal axis.
- the tool also has a suction channel extending at least partially axially along the longitudinal axis of the tool for sucking away drilling dust, wherein the suction channel runs from the end face of the tool head inside the tool shank and opens on the circumference into a connection opening in the tool shank.
- the connection opening may be, for example, a transverse, in particular obliquely oriented to the tool longitudinal axis bore.
- the tool head Due to the fact that the tool head is slotted on the end side in the axial direction, the tool head is subdivided into cantilevered webs which can deflect radially inwards. This radial compression of the tool head allows penetration into a borehole.
- the circumferentially arranged cutting means can therefore resiliently press in the radial direction against the surface to be roughened borehole. In this manner, by inserting the tool into a wellbore, a radial biasing force can be generated between the tool and the wellbore surface which, upon tool rotation, causes the cutting means to penetrate into the wellbore surface.
- the radial cutting forces are therefore generated by a resilient elastic bias, without a tumbling movement or eccentric movement of the tool is required.
- the user therefore only has to perform a translatory tool movement corresponding to a drilling process.
- the vibrations of the tool during the Roughening can thus be minimized.
- the wear of the cutting means can be reduced by the radial elasticity of the tool head.
- the cutting means can avoid collision structures, such as reinforcing iron or hard rock, in which the cutting means are displaced in a radially inward direction upon contact with these materials.
- the circumferentially arranged cutting means describe an enveloping circle whose diameter is greater than the nominal diameter of the borehole to be machined.
- the webs with their circumferentially arranged cutting means are displaced through the borehole surface in a radially inward direction, so that the slot of the tool head is narrowed.
- the bias of the tool in this case depends only on the dimensions of the tool and the nominal diameter of the borehole. Thus, a defined, radial bias of the tool can be generated.
- the suction can already be sucked out of the well during the roughening of the resulting drilling dust. In this way, an accumulation of drilling dust in the bottom of a blind hole boring well as a smearing of the roughened borehole surface by drilling dust can be avoided.
- the slots may be considered part of the suction channel.
- the suction opening can be varied on the tool head.
- An optimal suction of the tool is achieved by the direct extraction of Bohrstaubes at the place of origin, this means at the head of the tool so at the head of the tool head in the area of the cutting means.
- longitudinal bores can open from the end face of the tool head in the longitudinal bore of the shaft and thus transport the Bohrstaub from the head of the tool, through the tool shank to the suction.
- Another way to put the suction end face is to extend the longitudinal bore through the tool head by means of a conduit means, such as a hose or the like, through the slot to the head end of the tool head.
- the conduit means must be flexible and temperature stable so as not to interfere with the movement of the bars when engaging the wellbore. Furthermore, the conduit means must have a sufficiently large diameter in order not to hinder the extraction of the drilling dust and any accumulating cuttings. Thus, the suction of air through the sides of the slot, which can lead, especially with wider and longer slots, that little drilling dust is sucked, prevented and placed the air flow to the head end of the tool head. Alternatively, other options are conceivable to keep the slot flexible and yet seal.
- a further development of the tool according to the invention can be achieved by providing an adapter which surrounds the tool shank in the area of the connection opening and which has a connecting piece for connecting a suction device, the adapter having a cavity which peripherally surrounds the shaft in the area of the connection opening, so that a connection for discharging drilling dust is formed between the connection opening and the connecting piece.
- the adapter With the aid of the adapter, it is therefore possible to connect the tool to a suction device in a simple manner.
- the cavity enclosing the shaft circumferentially in the area of the connection opening ensures that suction can take place in the region of the tool head at any time during rotation of the tool shaft.
- the drilling dust can be fed to the suction channel via the slit (s) both at the front and at the side.
- the tool shank is rotatably mounted in the adapter according to an advantageous embodiment, wherein the tool is sealed in particular to the environment.
- the suction may therefore take place during the roughening process in such a way that the shank of the tool rotates relative to the adapter while the adapter is resting on itself.
- the sealing of the tool allows a safe catching of the drilling dust, whereby a pollution of the environment is avoided.
- the tool head may have at least two, radially resilient webs extending along the slot, which bear the peripheral cutting means at their free end portions adjacent to the end face.
- the arrangement of the cutting means near the end face the deflection of the webs is favored in the direction of the tool longitudinal axis, and the borehole is roughened to the end.
- the axial longitudinal extension of the slot may correspond to a multiple of the axial longitudinal extension of the free end portion on which the cutting means are arranged. The further the slot extends into the tool head in the axial direction, the greater is the lever arm provided by the webs, so that the radially inwardly directed compression of the cutting means arranged in the region of the end sections is facilitated.
- the tool head may have at least two intersecting slots, which extend from an end face of the tool head axially along the tool longitudinal axis.
- the tool head can consequently have four webs which extend along the slots and which carry the cutting means on the circumference in each case. With the number of slots increases the radial elasticity of the tool, so that the tool can be easily inserted into a wellbore.
- a plurality of intersecting slots may be provided in the region of the tool head.
- a first slot may have a greater length along the tool longitudinal axis than a second slot.
- the slots of the tool head can intersect at an angle less than or equal to 90 °.
- the slots can penetrate the tool head in particular substantially perpendicular to each other.
- an angle position of the slots deviating from 90 ° can alternatively be provided so that the webs have different cross sections. If, for example, two slits form an angle smaller than 90 °, then four webs are formed.
- a first pair of webs arranged opposite one another in this case has a smaller wall thickness than a second pair of webs arranged adjacent to these webs.
- the tool is designed symmetrically.
- the tool can be designed such that the tool has a homogeneous radial stiffness, so that during the roughening dynamic loads or an imbalance due to the tool bias can be avoided.
- at least two webs can be formed point-symmetrical to a tool longitudinal axis.
- at least two webs may be formed mirror-symmetrically to a tool plane, wherein the tool longitudinal axis lies in the tool plane.
- a slot may be formed in the tool in such a way, which have at least two webs facing each other, substantially parallel Plinkenen.
- the slot width at the head end of the tool head is preferably dimensioned so that the two webs just do not touch at maximum necessary deflection of the cutting means.
- the slot width depends on the nominal diameter of the borehole, for which the tool according to the invention is to be used.
- the dimensioning of the slot width at the opposite end of the slot, ie at the end of the tool head facing away from the base of the slot defines the spring stiffness of the webs and may necessarily be smaller than the required slot width at the head of the tool head. This can be made possible, for example, via a gradation in the slot progression.
- the slot has an area in the direction of the tool longitudinal axis, starting from the head end of the tool head to a greater width than over the adjoining area in the direction of its end face facing away from the bottom.
- a designed tool is particularly suitable for small hole diameter.
- the slot may have a concave fillet on its base facing away from the end face. This rounding off can be formed by a through bore, in particular introduced transversely to the longitudinal extension of the slot into the tool head. The rounding reduces a notch effect in the area of the base of the slot and adjusts the spring stiffness or the contact force of the cutting means to the borehole wall.
- the cutting means of the tool may comprise at least two radially extending carbide and / or diamond pins pointing away from the tool longitudinal axis.
- the pins preferably each form a geometrically determined cutting edge, which allow a defined introduction of furrows or undercuts in the borehole surface. This makes it possible to produce the pins used from a hard and the webs of an elastic material.
- the pins end radially outwards, in particular in a truncated cone or hemispherical shape.
- a plurality of carbide and / or diamond pins are provided, which are distributed in the axial direction and / or circumferentially on the tool head.
- a web may carry a single or a plurality of hard metal pins.
- the carbide pins can be circumferentially distributed on the web or arranged axially along the tool longitudinal direction consecutively.
- two or more, in particular three, hard metal pins can be provided on a web.
- the hard metal pins can be tightly packed in an axial direction in an end section of the web which is assigned to the end side or can be arranged closely adjacent to one another.
- the cemented carbide pins may be arranged circumferentially distributed on an outer circumferential surface of the web at the same axial height with an angular distance from one another.
- the tool head may be substantially circular cylindrical in accordance with a further embodiment of the tool.
- the diameter of the cylinder in the radial direction limiting outer lateral surfaces is preferably smaller than the nominal diameter of a borehole to be machined.
- the tool shank has at least twice, preferably at least three times, the length of the tool head in the axial direction.
- the diameter of the tool shank may be less than the diameter of the tool head.
- the tool can be made easy and flexible in this way, which improves overall handling during operation.
- the slot is at least partially filled with an elastic filling material, in particular an elastomer according to a development of the tool according to the invention.
- an elastic filling material in particular an elastomer according to a development of the tool according to the invention.
- the filler material By the filler material, the radial stiffness of the tool head can be increased. Further, the filling material may serve to dampen vibrations during machining of the wellbore surface.
- the suction channel may be formed in the tool head by the at least one slot and in the axial direction of the slot through a bore which is coupled to the slot or slots.
- the suction channel may be formed by a bore extending up to the end face into which the at least one slot opens radially.
- the slot if there are multiple slots, preferably all the slots, are preferably linear and beyond the center axis of the tool.
- a geometrically determined cutting geometry is provided in the region of the tool head in addition to the peripheral cutting means, in particular in the manner of a drill.
- the end face of the tool head may have an axially split along the tool longitudinal direction or slotted drill bit.
- two webs each of which carries cutting means in the region of an outer lateral surface, can each form a cutting wedge on the face side.
- the cutting edge may be formed by a cutting plate mounted on the web or by the web itself.
- the nominal diameter of the borehole may preferably be smaller than the diameter of an enveloping circle defined by the circumferential cutting means.
- the borehole surface can be roughened from a well bottom over the entire length measured in the axial direction.
- a cleaning after treatment of the well such as rinsing or blowing, can be dispensed with in this case, since the resulting during the Aufraureas dust is sucked directly.

- FIG. 1 shows an embodiment of a tool according to the invention in a perspective view.
- Fig. 5 shows an embodiment of the tool head with a cutting edge geometry
- Fig. 6 shows an embodiment of the tool head with a gradation in the slot profile.
- FIG. 1 shows an embodiment of a tool 10 for roughening a borehole surface.
- the tool 10 has a coupling portion 12 for clamping the tool 10 into a drill (not shown), a tool head 14 for machining a borehole surface (not shown), and a tool shank 16 connecting a coupling portion 12 and tool head 14.
- the coupling portion 12 is at a first end and the tool head 14 is disposed at a second end of the tool shank 16 opposite the first end.
- the tool shank 16 has more than twice the length of the tool head 14 along an axial direction a.
- the diameter of the tool shank 16 corresponds to that of the coupling section 12 and is less than the diameter of the tool head 14.
- the tool head 14 is substantially cylindrical and has circumferentially arranged, radially projecting hard metal pins 18.
- the carbide pins 18 are turned radially outward and extend in a radial direction r1 transversely to the axial direction a.
- the tool head 14 has a slot 20, which extends from an end face 22 of the tool head 14 axially along a tool longitudinal axis A and laterally from a lateral surface portion to an opposite runs, that is laterally continuous and divides the tool head 14.
- the tool head 14 thus has two webs 24 extending along the slot 20.
- the webs 24 carry at their end faces 22 adjacent to the free end portions 26, the peripheral hard metal pins 18.
- the webs 24 are designed mirror-symmetrically to a plane spanned by the axial direction a and the radial direction r2.
- the webs 24 have mutually facing planar surfaces 28 which have a constant distance from one another.
- the slot 20 has a substantially constant gap width.
- the slot has at its end facing away from the end face 22 a concave fillet 30.
- the fillet 30 is a radial through hole.
- the tool 10 is inserted with its tool head 14 into a borehole.
- the tool 10 is clamped with the coupling portion 12 in a drill.
- the nominal diameter of the borehole is less than an outer shell circle diameter of the tool 10 defined by the hard metal pins 18.
- the carbide pins 18 are therefore displaced radially inwardly of the borehole surface in the direction of the tool longitudinal axis A.
- the slot 20 is narrowed in this way. In this condition, the carbide pins 18 abut the wellbore surface and are resiliently biased against the wellbore surface via the resiliently inwardly bent lands 24.
- Tool rotation caused by the drilling tool causes the hard metal pins 18 to penetrate the wellbore surface and introduce furrows or undercuts into the wellbore surface.
- the borehole may be a blind hole.
- the tool 10 For roughening the borehole surface, the tool 10 only has to be introduced translationally along its tool longitudinal axis A into the borehole.
- the radial cutting forces are solely due to the resilient elastic bias of the tool head 14 reached, so that no radial force has to be initiated by the user in the tool 10.

- the slot opens into a central bore 40 (here blind hole), which extends to close to the coupling portion 12.
- In the bore 40 peripherally opens a radial connection opening 13th
- an adapter 15 which surrounds the tool shank 16 on the circumference is provided.
- the adapter 15 has a cavity 17 and a connecting piece 19.
- the connecting piece 19 is provided for connecting a suction device (not shown).
- the cavity 17 encloses the shaft 16 circumferentially in the region of the connection opening 13. In this way, a connection for discharging drilling dust between the connection opening 13 and the connecting piece 19 is formed.
- the tool shank 16 is rotatably mounted in the adapter 15.
- the tool 10 is sealed to the environment.
- the tool shank 16 which is driven by a drill, rotates within the stationary adapter 15.
- An extraction device is connected to the connecting piece 19. Through the cavity 17 ensures that the suction is ensured during the rotation of the tool shank 16 in each angular position.
- the drilling dust can be supplied to the suction channel 1 1 via the slots 20 both frontally and laterally.
- the bore 40 can also extend to the end face 22, so that here a hole with a uniform cross-section is present.
- the one or more slots 20 then open radially in this central bore 40th
- FIGS. The representations of the tool heads 14 are to be understood only as examples. It is understood that for each of the variants shown, the slots 20 open in the axial direction in the suction channel 1 1 or pass over, so that a suction of drilling dust in the region of the tool head is made possible. In particular, the slots 20 can be considered as part of the suction channel 1 1.
- FIGS. 3a to 3c illustrate three different variants for the arrangement of slots 20 in the region of the tool head 14.
- FIG. 3a shows a tool head 14 in a perspective view and a front view.
- the tool head 14 has two slots 20 intersecting in the central axis of the tool, so that a total of four webs 22 are formed, each of which carries a hard metal pin 18.
- the tool head 14 is constructed symmetrically.
- Figure 3b also shows a tool head 14 with two intersecting slots 20, but with one of the slots 20 along the tool longitudinal axis having a greater length than the other slot.
- FIG. 3 c shows a further variant of a tool head 14, which differs from the variants described above in that the slots 20 do not penetrate the tool head 14 at a right angle, but are oriented at an angle to one another.
- the pairs of oppositely arranged webs 24 therefore have different wall thicknesses and cross-sections, as the front view can be seen.
- Figures 4a and 4b show variants for the arrangement of hard metal pins 18 in the region of the tool head 14.
- Figure 4a shows an axial arrangement of the carbide pins
- Figure 4b shows a circumferential distribution, in which the carbide pins are arranged relative to the tool longitudinal axis at an angular distance from each other.
- Figure 5 shows an embodiment of the tool head 14 with a cutting geometry 34.
- the webs 24 are frontally shaped in the manner of a drill, wherein through the slot 20 a along the tool longitudinal axis A split drill bit is formed.
