Abstract

The invention discloses an alloy hole opener. The alloy hole opener comprises a head part and a handle part connected with the head part, wherein hard alloy blades are arranged at the end of the head part; each hard alloy blade is in a rectangular pyramid shape; one rectangular face in each rectangular pyramid is connected with the head part; a chip discharging groove is further formed between the adjacent hard alloy blades. According to the alloy hole opener, a blade tooth opening is not easy to abrade, the service life is longer and the hole opening speed is rapid.

Description

technical field [0001] The invention relates to hardware devices, in particular to an alloy hole opener. Background technique [0002] The hole saw is also called the cutter. It is installed on an ordinary electric drill and can easily make round holes, square holes, triangular holes, and straight lines on any curved surface such as copper, iron, stainless steel, and plexiglass. , Arbitrary cutting of curves. Flexible, convenient, safe and versatile. [0003] However, the tooth edge of the hole saw blade of the traditional alloy hole saw wears out quickly, and the hole opening speed is slow. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an alloy hole opener, which is not easy to wear and tear, has a longer service time and a faster hole opening speed. [0005] In order to solve the above technical problems, the present invention provides an alloy hole opener, which includes a head and a handle connected to t...
