KBC TOOLS & MACHINERY’s Shark taps by Dormer are color-coded to ensure true efficiencies in tapping and the right tap for the right material. Shark taps are manufactured from powder metallurgy tool steel different from any other HSS-E-PM, with a TiAIN-top coating. This provides high-impact toughness, increased hot and consistent hardness, and edge strength, allowing the taps to perform at higher cutting temperatures while offering excellent performance and longer tool life.
The thread geometry and chamfer result in low torque, excellent threads, and surface finishes, as well as reduction in axial forces.
Black spiral point taps are for high strength steels and heat-resistant work materials with hardness up to 45HRC. These are recommended for use with rigid tapping for through-hole threading up to 2.5xD
Blue spiral point and spiral flute taps for stainless steel have TiAIN + WC/C coating (Super B) with an additional edge treatment. Operators can tap through hole and blind holes in stainless with ease and repeatability.
Red spiral point taps are for high performance blind hole tapping in most medium alloy steels. The taps have a back taper that further facilitates chip evacuation which results in reduced chipping of the last threads of the taps and lower torque when the tap reverses. Recommended to use a tool holder with minimal float or soft start.
Yellow spiral flute and spiral point taps are for through-hole tapping in structural, plain carbon, and low alloy steels.
White straight flute taps are for semi-bottoming or through-hole tapping in cast iron.
