Abstract

The invention discloses a resource-friendly economical EDU drill bit which comprises a drill handle and a drill bit body installed at one end of the drill handle, two spiral chip grooves are formed in the side wall of the drill handle, a positioning pin is arranged at one end of the drill bit body, an inserting hole for the positioning pin to be inserted is formed in one end of the drill handle, and a clamping block is integrally formed on the side wall of the positioning pin. The side wall of the inserting hole is provided with a sliding groove for sliding connection of the clamping block and an arc-shaped groove connected with the clamping block in a clamped mode. According to the scheme, after the drill tip of the drill bit is seriously abraded after being used for a long time, a worker only needs to disassemble the drill bit, so that the clamping block on the positioning pin is separated from the arc-shaped groove in the drill tip and enters the sliding groove, and the worker can conveniently disassemble the drill tip towards the side away from the drill handle; according to the EDU drill bit, the abraded drill point can be conveniently and independently replaced by a worker, the tedious operation that the worker needs to wholly replace the EDU drill bit and then resets the tool is avoided, and the economical performance and the resource friendliness of the EDU drill bit are improved.

Description

technical field [0001] The invention relates to the technical field of drill bits, in particular to a resource-friendly and economical EDU drill bit. Background technique [0002] Drilling is a method of processing mold parts holes on a drilling machine with a drill bit or a reaming drill. It is easy to operate, strong in adaptability, and widely used. By monitoring and measuring during the processing and adjusting the adjustable tool, the error generated in the processing can be compensated, which can greatly meet the requirements of processing safety. [0003] An EDU drill bit is disclosed in the related art, which includes a drill shank and a drill bit detachably connected to one end of the drill shank. The connection between the drill bit and the drill shank is detachable. When the tip of the drill bit is severely worn after long-term use, the staff needs to disassemble the drill bit as a whole. After replacing the drill bit, the staff needs to re-set the tool. The oper...
