4-40 H2 SF SP POINT BLACK SHARK TAP

FOR HIGH STRENGTH STEELS

Designed for high performance blind hole tapping in high strength and heat resistant work materials with hardness up to 45HRC.

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:
Low helix spiral flute geometries with low rake angle for good chip control and edge strength.
Features a special three-radii profile with constant rake angle along the flute length leading to better control of cutting properties and prevents nest formation of chips. It has a balanced higher relief on the chamfer (cutting threads) and lower relief on the guidance threads. This supports:

• Process security.
• Superior surface finish.
• Highly accurate threads
• Blind hole threading up to 1.5xD.

SURFACE TREATMENT:
TiAlN-Top coating combined with geometry that significantly increases cutting edge strength, provides excellent performance and consistency in hard and difficult to machine materials.

FEATURES:

• The color ring on the tool shank identifies suitability for specific materials and enables quick and easy tool selection.
• When using Black Shark taps, it is recommended to use synchronized (rigid) tapping.
