Problems solved by technology

[0002] When the traditional drill bit is in use, it cannot be positioned on the workpiece by itself, and it often needs the help of the operator to perform positioning, which increases the workload of the operator and reduces the work efficiency of the operator. It is easy to slip, especially when encountering a workpiece with high strength. Once it slips, i...

Abstract

A high-performance antiskid shank shrinkage drill bit comprises a drill bit body and a clamping device. The drill bit body is a twist bit. Cutting edges are arranged on the drill bit body and intersect with one another. The clamping device is arranged around the drill bit body and is a jaw, and the jaw is a four-foot jaw and is provided with fixed pieces. The fixed pieces are rectangular fixed blocks. Absorption pieces are arranged on the rectangular fixed blocks and distributed on the jaw. The clamping device is arranged on the drill bit, and therefore machining of the drill bit can be facilitated, and the situation that the drill bit skids on a workpiece, and consequently the quality of the outer surface of the workpiece is influenced can be avoided; meanwhile, the locating effect of the drill bit can be improved, the drill bit can be located conveniently by itself, and the work efficiency of the drill bit is improved; and a sheath is arranged on a connecting shank and can protect the connecting shank, and the connecting shank is prevented from being rusted.

Description

technical field [0001] The invention relates to a drill bit, in particular to a high-performance anti-slip shrinking shank drill bit. Background technique [0002] When the traditional drill bit is in use, it cannot be positioned on the workpiece by itself. It often requires the help of the operator to perform positioning, which increases the workload of the operator and reduces the work efficiency of the operator. Some drill bits are in use. It is easy to slip, especially when encountering a workpiece with high strength. Once it slips, it will leave scratches on the surface of the workpiece, which will affect the smoothness of the surface of the workpiece, so that the outer surface of the workpiece must be polished during subsequent processing. The manufacturing cost of the workpiece is increased, and the service performance of the drill bit is greatly reduced, so that the use effect of the drill bit is reduced. Contents of the invention [0003] The purpose of the prese...
