Like turning a gradual replacement carbide cutting tools, like high-speed steel cutting tools, carbide taps began more

Taps
For threaded hole machining, compared with high-speed steel, high alloy hardness, brittleness, carbide tap tapping, chip processing problems. Nonetheless, carbide taps for machining cast iron and aluminum materials, the use of good results, in the form of tap breakage mainly mechanical wear.
Due to a large number of automotive machining cast iron and aluminum parts, the use of carbide taps for long life of the tool. When the workpiece reinforced concrete cutting wheels machining these materials, carbide taps a longer life than high speed steel cone. In the automotive industry, wire push to reduce significantly change time is an important factor, and long life carbide filaments push will make change time is minimized. With a small helix angle of the surface coating on the silicon carbide content of the tap 8% -12% of the tapping of aluminum alloy, and its effect is very good. With sub-micron particles (Submicron-grain) produced carbide taps, increase tool toughness without reducing its hardness when cutting hardened steel, plastics and hard machining nickel-based alloys with good results.
