M16 DIN 376 C R40 (6H) HSSE-Co5 TiN 800EX EL-CUT maschio a scanalature elicoidali

The M16 DIN 376 C R40 (6H) HSSE-Co5 TiN 800EX EL-CUT is a high-performance spiral point tap designed for efficient threading in through holes. Manufactured from premium HSSE-Co5 (High-Speed Steel with 5% Cobalt) and coated with Titanium Nitride (TiN), this tap offers exceptional wear resistance and extended tool life. It conforms to DIN 376 standard with a C chamfer form (2-3 threads) and a 6H tolerance class for precise metric threads.

Advantages

This tap features a reinforced shank and a spiral point (gun tap) geometry that pushes chips forward, preventing clogging and ensuring smooth cutting. The TiN coating reduces friction and heat buildup, allowing for higher cutting speeds and improved surface finish. The R40 variant is optimized for a wide range of materials, including steel, stainless steel, cast iron, and non-ferrous metals.

Suitable for

• Through hole threading in steel, stainless steel, cast iron, and non-ferrous metals
• Industrial manufacturing and maintenance applications
