DORMER 4-40 H2 SP FLUTE RED SHARK TAP

FOR ALLOY STEELS

Designed for high performance blind hole tapping in most medium Alloy Steels.

MATERIAL:
Shark taps are manufactured from a unique powder metallurgy tool steel different from any other HSS-E-PM. This provides an unbeatable combination of toughness and edge strength, allowing the taps to perform at higher cutting temperatures while offering excellent performance and longer tool life.

• Higher impact toughness
• Increased hot hardness
• Consistent hardness

GEOMETRY AND CHAMFER
Thread geometry with optimized form generates:

• Low torque
• Excellent threads at both high and low speeds
• Superior surface finish

SURFACE TREATMENT
TiAlN-Top is a multi-layer ceramic coating which has been through a post-coating smoothing process. It exhibits high toughness and oxidation stability making it ideal for higher speeds while also improving tool life.

FEATURES:

• The color ring on the tool shank identifies suitability for specific materials and enables quick and easy tool selection.
• Significant reduction in axial forces and torque compared to conventional taps. This ensures problem-free threading of blind and through holes in the selected material.
• Standard ANSI shank and square with DIN overall length, for extra reach and compatibility with Inch Standard Tap Holding.
• Spiral flute taps 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.
• The back taper on spiral flute Red Shark further facilitates chip evacuation, reducing chipping on the last threads of the taps and also reducing torque when the tap reverses.
• When using spiral flute Red Shark taps, it is recommended to use a tool holder with minimal float or soft start.
