Material-specific taps

Material-specific taps

June 12, 2018


The Shark Line of Dormer taps are material-specific taps offering high performance and process security. The tools are easily recognizable by their color ring coding on the shank which identifies material suitability and supports quick and easy tool selection.

The Yellow Shark is for structural, carbon and low alloy steels, Red Shark for alloy steels, Blue Shark for stainless steels and White Shark for cast irons.

The Shark Line is available in standard ANSI shank and square with DIN overall length, offering extra reach and compatibility with Inch Standard Tap Holding. The taps' advanced geometry provides a significant reduction in axial forces and torque compared to conventional taps. This ensures problem-free threading of blind and through holes.

All Shark taps are manufactured from a powder metallurgy tool steel, which is uniquely different to other HSS-E-PM based cutting tools available. This provides a combination of toughness and edge strength, allowing the tap to perform at higher cutting temperatures while offering excellent performance and tool life.

The spiral flute taps (Yellow, Red and Blue Shark) incorporate a special edge treatment to increase strength and reduce the chance of micro-chipping on the cutting edges. This considerably improves performance and tool life.

An internal coolant option (White Shark Form E taps) improves tool life, provides optimum chip evacuation when threading short chipping materials and is extremely beneficial in horizontal blind-hole machining.
