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 Application Taps optimized for specific materials and taps optimized for versatility Suitable for both through holes and blind holes Available in many thread forms and stan¬dards Depths up to 3.5 × diameter Available with internal coolant in thread forms M Tolerances: ISO N: 6H, 2B Multi: 6G, 6GX, 6H, 6HX, 2B, 2BX
