Effective chip removal can be ensured during the thicker workpiece of working thickness, flute bottom sets chip removal chamfering to be use up when tubular cover body rotates
It is possible to drive chip to outside, avoid falling into tubular mask body intracavity.
The utility model is further arranged to, and the cutter head number is even number, double of quantity on the cutter head
Carbide bit, the main cutting edge above it and chamfered corner is provided between the front cutting edge of its both sides, provided with rose reamer
The carbide bit of carbide bit and the no chamfered corner of point is distributed in distance setting.
In said structure, by setting chamfered corner, the carbide bit master provided with chamfered corner can be made to cut cutting edge
The bottom hole that hole is outputed with perforate is cut；And the carbide bit for being not provided with chamfered corner does not switch to for cutting chamfered corner
Part workpiece material, to share the degree of wear between carbide bit, improve service life.
The utility model is further arranged to, and is not provided with the carbide bit of chamfered corner, its main cutting edge and its
The nose angle formed between the front cutting edge of both sides is less than 90 degree and is more than 60 degree.
The utility model is further arranged to, and the external wall of cylindrical cover is provided with some with its inner chamber to logical chip removal
Road, the chip removal channel are set in the shape of a spiral along the external wall of cylindrical cover, its lead angle and rotation direction during tubular cover body perforate
Conversely.
In said structure, chip removal channel can be used for surprisingly falling into the chip of tubular mask body intracavity during discharge perforate, while can be with
Increase air circulation, play a part of cooling.
The beneficial effects of the utility model：Chip removal effect is good, and cutter head quantity is more, and sharpness is high, service life length, and perforate is steady
Fixed not easy tooth-breaking.

Embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to the scope of the utility model.
Referring to figs. 1 to Fig. 3, a kind of hole making drill as shown in Figure 1 to Figure 3, including tubular cover body 10 and connecting shaft 11 are described
The inner chamber of tubular cover body 10 is provided with the spitting drill mounting hole 12 for being used for placement positioning and boring, the tubular cover body with the connecting place of connecting shaft 11
10 are provided with some cutter heads 13 relative to one end of connecting shaft 11, and chip area 14 is provided between adjacent cutter head 13, described
Carbide bit 131 is welded with cutter head 13, the chip area 14 opens up depth more than between adjacent cutter head 13
Spacing, the bottom of chip area 14 is curved, the bottom of chip area 14 close to the side of the outer wall of tubular cover body 10 be provided with row
Consider chamfering 141 to be worth doing.
In said structure, carbide bit 131 is arranged at the end of cutter head 13, due to hole making drill cutting when only
It is the sub-fraction participation cutting of carbide bit 131, therefore substantial amounts of Hardmetal materials can be saved, chip area 14 opens up
Depth is deep, can ensure effective chip removal in the thicker workpiece of working thickness, and the bottom land of chip area 14 sets chip removal chamfering 141 can be in cylinder
