Product Description
The Bohrcraft DIN 376 HSS-E Co 5% spiral flute cobalt machine tap M 12 x 1,75 Form C 35° RSP is engineered for demanding blind-hole tapping applications up to 2.5xD depth in tough materials, including alloyed steels, stainless steels, and heat-resistant metals up to 1000 N/mm². The 35° spiral flutes evacuate chips reliably out of the blind hole while the 5% cobalt alloy preserves cutting edge sharpness under severe thermal stress. Form C lead chamfer (2–3 threads) allows full-depth threading close to the hole bottom.
Features and Benefits
- 5% cobalt alloy (HSS-E) delivers maximum heat resistance and edge retention
- 35° spiral flutes efficiently lift chips out of blind holes
