Carbide cutting tap machining non-ferrous materials such as aluminum spiral flute tap selection, cutting light, smooth chip; machining brittle materials such as cast iron straight flute tap selection, good rigidity, long life; processing of high hardness steel, use special geometries and optimized design of special taps, HSS taps can solve the problem difficult to solve; processing thread through holes, use blade angle tap, chips flowing from the front, and rigid than ordinary tap straight groove, life should be higher than 2 times. Processing of non-ferrous metal and alloy extrusion tap ≥10 ductility of steel, using extrusion tap, you can get high-strength, surface smoother thread, but life than cutting tap tap increased more than 2 times. Especially small diameter threaded processing, extrusion tap life will be more than 5 times. Carbide drilling and tapping tap processing complex aspect ratio ≤1.5 times threaded through holes, cast iron and aluminum material, before the selection of diamond drill attack after attack complex taps, drills and taps so you can put together the perfect combination to improve drilling and efficiency, but also improve the accuracy of location is a good program to serve multiple purposes. Carbide thread mills, cutting a wide range of multi-purpose knife, is the most advanced threading tools.
