size of screw tap

Recently, aiming at the pain point of screw tap wear during high-strength steel machining, our company has completed a major upgrade to the coating process. Field tests have shown that the service life of the new screw tap has increased by 30%, which has been recognized by many factories.​
Traditional screw taps are prone to wear under high temperature and pressure when machining 45# steel, chromium-molybdenum steel, etc., requiring frequent replacement. This upgrade adopts TiAlN composite coating, which can withstand temperatures up to over 800℃ and has a hardness increased to HV3200. Combined with the multi-arc ion plating process, the coating adhesion has been enhanced by 40%, effectively preventing wear-induced failure.​
The supporting Tap set includes upgraded screw taps of various specifications, suitable for machining metric (M2-M30) and imperial (1/4-1 1/4) threads. When used with a dedicated Tap wrench, tool change becomes more convenient and downtime is reduced. After a certain auto parts factory adopted this Tap set, its daily production capacity increased by 8% and the defective rate dropped to 0.8%.​
Currently, the upgraded screw taps and Tap sets have been put into mass production and can be customized according to the machining materials. For free samples or to learn about Tap wrench adaptation solutions, please consult our online consultant.
