Sandvik Coromant Co. Forming Taps CoroTap 400

Forming taps form the thread instead of cutting. This is a chip-free solution that is suitable for both through and blind holes. All materials are not suitable since there is need of certain ductility; recommended tensile strength limit is 1200 N/mm2. Forming taps are available with and without oil grooves.

Features

• Chamfer C (2-3 threads) and chamfer E (1.5-2 threads). Chamfer E mainly used in blind holes with low clearance
• High speed steel with cobolt taps for improved wear resistance
• High speed powder steel taps for improved strength, wear resistance and tool life
• Solid carbide taps for superior tool life and highest productivity
• Three different coatings are available:
• TiCN – used on our solid carbide forming taps. Combines low friction with high hardness
• TiN – all-round coating with low friction
• CrN – excellent for ISO N materials and low alloyed steel
