Abstract

The invention discloses a hard alloy tapper which comprises a head part and a handle part connected with the head part, wherein a sawtooth-shaped hard alloy blade is arranged at an end of the head part; one side of the sawtooth-shaped hard alloy blade is in a straight form; two peaks extend to the bottom of the sawtooth on the other side of the sawtooth-shaped hard alloy blade; a chip outlet is formed in the head part. The hard alloy tapper has the advantages that the blade and the tooth edge are difficult to be abraded and the service life is longer.

Description

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