Background technique
Drill bit be on solid material drilling go out through-hole or blind hole, and can be to the cutter of existing hole reaming.It is common
Drill bit mainly have fluted drill, chit drill, centre drill, depth drill and cylindrical drill.Though reamer and counterbit cannot be on solid materials
Drilling, but they are also traditionally included into drill bit one kind.Drill bit includes the drilling for the drillstock of clamping and for being ground drilling
Portion, under high-speed rotation, the rigidity of drill point is insufficient, and the top of supply line in drilling portion is easy to happen beat or bounce.The prior art
Drill bit includes working portion and shank, is linked together, and the surface of shank is even surface, and when processing is clipped in drill jig or lathe
In the hole of main shaft, the frictional force between shank and collet is small, and drill bit is made to be not easy to clamp.Spiral fluted drill is conducive to volume bits and breaks
Bits, but it is easy that hole drill is inclined, and straight-flute drill is then capable of processing out the higher hole of straightness.
Utility model content
In order to overcome the defect in the presence of the prior art, the utility model provides a kind of novel drilling machine bit.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of novel drilling machine bit, packet
Drillstock, straight knife part, circular knife part, apex point, interior cold hole are included, the drillstock is cylindrical structure, and the straight knife part includes
Straight knife back and straight knife slot, the circular knife part include spiral knife spine and spiral cutter groove, and the drillstock and straight knife part one end are solid
Fixed to be connected, the other end of the straight knife part and one end of circular knife part are fixedly linked, the other end of the circular knife part
On have apex point, have interior cold hole on the apex point, entire drill bit is run through in the interior cold hole, coolant liquid can be added by interior cold hole,
Help to radiate, avoid temperature of diamond bit excessively high, while facilitating chip removal, the drillstock, straight knife part, circular knife part, apex point,
Interior cold hole is integrally formed, and each section central axis is located in a straight line.Spiral cutter groove is conducive to volume bits and chip breaking, circular knife portion
Divide and be connected with straight knife part, and chip space communicates, the straight knife part of drill bit is capable of processing out circularity and the higher hole of straightness, effectively
The rigidity for improving entire drill bit, mitigate beat of the drill bit under high speed rotation, the straight knife part of drill bit is chip removal hole
A direct channel is provided outside.
Above-mentioned one kind novel drilling machine bit has annular knurl line on the drillstock of cylindrical structure, is conducive to boring
Head is fixed in drill jig, prevents bit bounce in use, improves security performance.
The novel drilling machine bit of above-mentioned one kind, the straight knife slot connect and communicate with spiral cutter groove.
The novel drilling machine bit of above-mentioned one kind, the surface of the straight knife part are evenly distributed with particles of silicon carbide,
Diamond dust hardness is big, effectively avoids the abrasion of drill bit, and antioxygenic property is good, indeformable at high temperature, can guarantee bored hole
Inner wall is highly polished, reduces the burr of hole inner wall.
The utility model has the beneficial effects that the utility model drill bit was combined using circular knife part with straight knife part
Mode, there is curved edge on apex point, and apex point connects circular knife part, and helicla flute is conducive to volume bits and chip breaking, circular knife part with
Straight knife part is connected, and chip space communicates, and the straight knife part of drill bit is capable of processing out circularity and the higher hole of straightness, effectively mentions
The high rigidity of entire drill bit, mitigates beat of the drill bit under high speed rotation, the straight knife part of drill bit is to mention outside chip removal hole
A direct channel is supplied.
