This utility model is further arranged to: be coated with diamond layer outside described drill bit.
By using technique scheme, silicon carbide layer strengthens the intensity of the drill bit of spitting drill, locating notch energy simultaneously
Enough increase the contact area of diamond layer, the contact area of silicon carbide layer during raising friction, thus abrasion thickness when completing boring
Degree can reduce.
This utility model is further arranged to: at described connecting shaft, side opening is provided with screwed hole, arranges in described screwed hole
Having dormant bolt, described spitting drill is provided with fixed gap, described dormant bolt is against stationary positioned at fixed gap and bores.
By using technique scheme, bolt is utilized to block spitting drill so that location turns the center being fixed on hole making drill,
Simple in construction, and can easily install and take off, thus disassembling, assembling and replacing, dormant bolt can be carried out as required in different occasions
Ensure that the smooth of surface at connecting shaft.
This utility model is further arranged to: described dormant bolt is hexagon socket head cap screw.
By using technique scheme, dormant bolt can easily be threaded into hole, and interior six by inner hexagon spanner
It is difficult at angle skid, easily operates.
This utility model is further arranged to: be provided with sword groove at described cutting edge.
By using technique scheme, arranging of sword groove facilitates passing through of coolant, before cutting can easily be abundant
Moistening cutting edge, on the one hand ensures that during cutting, temperature will not be too high, and the dust the most also avoiding cutting to produce splashes, it is ensured that cut
Safety when cutting.
This utility model is further arranged to: be provided with double thread on described spitting drill.
By using technique scheme, double thread is when boring, and chip removal speed is faster, it is to avoid detritus accumulated plugging is opened
At hole.
This utility model is further arranged to: be arranged with back-moving spring outside described spitting drill, and described spring one end is connected on even
In spindle.
By using technique scheme, during hole making drill perforate, the circular defective material scaled off is close with footpath in cylindrical cover body,
Easily being stuck in cylindrical cover body, back-moving spring has thrust, it is thus possible to avoid defective material the deepest to the defective material entering tubular cover body
Enter, facilitate defective material to take out.
This utility model is further arranged to: it is coniform that described connecting shaft connects one end of spitting drill.
By using technique scheme, the setting of cone-shaped structure, support triangular in shape to spitting drill, support effect is more
Good, it is ensured that intensity when spitting drill uses, it is to avoid spitting drill wrecks.
In sum, this utility model has the advantages that
1, notched spitting drill, has stronger stationkeeping ability;
2, bolt is utilized to support spitting drill in axial restraint spitting drill, one end of connecting shaft cone, it is ensured that spitting drill
Stable installation;
3, double thread cutting area is bigger, and efficiency is high.
