D/K Technologies Turret Taps are a powder metal roll form tap. This will give you better thread quality and alleviates the hassle of chips on your table. There are several different coatings offered to maximize tap life. All taps come with TiN coating unless otherwise noted.

Coatings:

Titanium Nitriding (TiN)
Provides a layer of titanium, which is applied to the tap surface with the PVD method. This treatment reduces the coefficient of friction and hardens the surface to 80-85 Rockwell C. The TiN treatment is ideal for the majority of forming applications. This treatment is not recommended for tapping titanium and has performed poorly in high nickel alloys, brass and galvanized steels. Titanium Nitride is the standard treatment on all Stub Jarflo taps.
TICN
Is a very hard PVD thin film coating. This coating is excellent for abrasive wear applications. It provides a hardness superior to carbide but maintains the toughness of high-speed steel.
Steam-Oxiding (J-100)
Provides a diamond blue/black finish that stress relieves the microstructure of the tap and provides an oxide film that reduces galling.
Nitriding (NQ-5)
Case hardens the cutting tool surface to 66-68 Rockwell C and provides increased wear resistance with a black surface finish that acts as lubricant to reduce frictional heat and galling.
