Introducing our "carbide taps," which can process stable and high-precision screw threads.
In recent years, the machines used for tapping have become specialized, automated, and have adopted NC machines and machining, leading to labor-saving advancements. In response to this era, we recommend our carbide taps, which are well-received for mass production and cost reduction. When used properly, they have been proven to have over 50 times the durability compared to standard HSS taps. The material of the carbide taps is carefully selected, using ULTRA-FINE-GRAIN-CARBIDE made from ultra-fine tungsten carbide and high cobalt, which are deemed suitable for taps.
