Description

A kind of new drill

Technical field

This utility model relates to field of drill, particularly relates to a kind of new drill.

Background technology

Drill bit is the cutter that boring is conventional, drill bit is when boring, mainly through bit tip, workpiece is cut, by chip area, chip is discharged, at present, drill bit material on market is single, function is simple, not only can affect the bright and clean degree of hole inwall flour milling during operation, make the hole inwall sand trace that drill bit gets out many, drilling effect is poor, and, for prior art, generally by after boring, chamfering is once again, then carry out ream put down, series of processes completes, different instruments and para-position must be changed through secondary when using the method for chamfering of first holing again, the para-position of Chang Yin center is inaccurate and causes bias, process is various, work efficiency is low.

Utility model content

This utility model is mainly solving the technical problems that provide a kind of new drill, it is possible to make hole inwall flour milling thin and uniformly, sand trace is few and shallow, and holing complete can carry out chamfering, the flat operation of ream at once.

For solving above-mentioned technical problem, the technical scheme that this utility model adopts is: provide a kind of new drill, it is characterized in that, including: drillstock, drill neck, apex point, chamfering, described drillstock is cylindrical structure, one end connects described chamfering, the described chamfering other end connects described drill neck, the described drill neck other end connects described apex point, described drill neck is provided with helical form chip area, described apex point is provided with two cutting edges, two described cutting edges are helically arranged centered by the central axis of drillstock, wherein, described chamfering is between described drill neck and drillstock, described drill neck, on apex point and chamfer surface, uniformly dispersing has particles of silicon carbide, described drillstock, drill neck, apex point, the central shaft of chamfering is positioned on straight line.

In one preferred embodiment of this utility model, the angle angular range of the fillet surface of described chamfering and drill neck is 120 °-150 °.

In one preferred embodiment of this utility model, described drillstock, chamfering, drill neck, apex point are integrally welded structure.

In one preferred embodiment of this utility model, described chip area number is 1-2, and its helical angle is 30 °-45 °.

In one preferred embodiment of this utility model, the angle of described apex point is 135 °.

In one preferred embodiment of this utility model, described particles of silicon carbide adopt plating, hot pressing, welding method be fixed on the drill neck of drill bit, apex point and chamfer surface.

The beneficial effects of the utility model are: this utility model simple in construction, add facing attachment on the basis of normal drill bit, while completing boring, face, hole are carried out chamfered, the apex point of drill bit, drill neck and chamfer surface arrange particles of silicon carbide, corundum hardness is big, is prevented effectively from the abrasion of drill bit, and antioxygenic property is good, at high temperature indeformable, ensure that the hole inwall bored is highly polished, sand trace is few and shallow, and is put down by chamfering ream, diverse in function, practical.
