Hole, drilling depth is up to 100 times of diameter, although the feed of every rotation of drill gun is relatively low, its amount of feeding per minute compares fried dough twist
Bore greatly, operator is firmly excessive in boring procedure to cause drill gun sinkage, on the one hand easily causes the failure of hole drill, another
Aspect easily causes to be processed the destruction in hole, causes scrapping for workpieces processing, adds the cost of processing.
Utility model content
The utility model easily causes the failure of hole drill for conventional holes power drill, easily causes to be added in operation
The destruction in work hole, cause workpieces processing the cost scrapped and add processing deficiency, propose that a kind of band stops the thin of section
Twist drill, stability axial in drill bit process can be increased considerably, chip removal is extremely smooth, can improve the essence of drilling
Degree, its processing efficiency also can obtain effective raising.
The technical solution of the utility model：A kind of band stops the sheet drill of section, including drill body and drillstock；It is characterized in that：
The drill body is made up of conical sections and cylindrical portion superposition, and the top of the drill body is provided with positioning apex point, the drill body
Tail end be provided with and stop saving, the section that stops be in oblate frustum structure, the drill body and stops section surface and be provided with inclined V-type arranging
Consider groove to be worth doing, the angle of the V-type chip area is 75 °, and the axis of the V-type chip area and drill body is in 15 ° of angles, the drillstock surface
Provided with three spot facings, each spot facing is in 120 ° of distributions.
The slot number of the V-type chip area is 2, and V-type chip area is mutually 180 °.
The taper ratio of the drill body conical sections is 1：3, diameter and the cylindrical portion diameter of conical sections bottom
It is identical.
The section that stops is in oblate frustum structure, and the upper bottom diameter of oblate frustum is identical with cylinder diameter, oblate frustum
Taper ratio be 1：0.75.
The positioning apex point is in conical apex point, and apex point drift angle is 118 °.
Drillstock surface ream has three rectangle for being mutually 120 ° spot facings, and the flat length of ream is equal with the radius of drillstock.
The beneficial effects of the utility model are：The utility model proposes a kind of band stop section sheet drill, it is rational in infrastructure,
Compared with traditional pistol drill bit structure, this new is additionally arranged stops section and positioning apex point, and boring procedure is more stable, tilting
V-type chip area make it that chip removal is more smooth, at the end of drilling, can effective protective drill drill bit part, improve drill bit
Service life, in addition, the machining accuracy for being processed hole is greatly improved, its processing efficiency, which also can obtain, effectively to be carried
It is high.
