Abstract

The invention provides a drilling tool. The drilling tool comprises a drilling tool body and a drilling tool bit, wherein a clamping handle and a first spiral groove are arranged on the drilling toolbody; a second spiral groove is arranged on the drilling tool bit; the second spiral groove is communicated with the first spiral groove; a cooling water hole is arranged on the drilling tool body; athird groove is also arranged on the drilling tool body; a positioning pin hole is arranged on the bottom surface of the third groove; a cylinder is arranged at the bottom of the drilling tool bit; the drilling tool bit is inserted into the positioning pin hole through the cylinder so as to be arranged in the third groove; and an inclined surface is arranged on the cylinder, a first threaded through hole is arranged at a preset position below one side wall of the third groove, a first screw penetrates through the first threaded through hole and clamps the cylinder through the inclined surface,and then the drilling tool bit is locked. According to the scheme, on the premise of keeping the clamping precision, the effective locking times are increased in multiple levels, and the drilling tool has high drilling efficiency.

Description

technical field [0001] The invention relates to the technical field of device drilling equipment, in particular to a drilling tool. Background technique [0002] The drilling tools used in the metal drilling process are often twist drills, which are drilled by rotating relative to a fixed axis, and are named for their chip flutes that are helically shaped like twists. The spiral grooves of traditional twist drills have 2 grooves, 3 grooves or more grooves, but 2 grooves are the most common. Twist drills can be clamped on manual or electric hand-held drilling tools or on drilling machines, milling machines, lathes and even machining centers. The material of the drill bit is generally high-speed tool steel or hard alloy, so the traditional metal drill bit is commonly called a high-speed steel twist drill or a hard alloy twist drill. In the actual metal drilling process, the high-speed steel twist drill has a shorter service life than the carbide twist drill, low cutting and ...
