DIC taps are manufactured from high speed steel with excessive vanadium content material for max durability in addition to most wear-resistance.
Chamfer length for blind hole is 2.5 threads. Thread accuracy complies with SP accuracy that is equal to JIS class 2 products and extra high accuracy products.
To in shape the blind hole tapping operations, the helical angle & shape of flute on a spiral flute tap were in particular designed. The most reliable helical angle design allows chips to be smoothly exhausted from the hole. The flute shape will enable chips to become fine and curled. For tapping on workpieces, which include alloy steels, carbon steels and non-ferrous metals, the series of taps features outstanding durability, high accuracy & longer service life.
