G 1/8 DIN-5156C R40 HSSE TiN Machuelo de máquina para rosca de tubo BSPP

With a 28 TPI pitch and TiN-coated HSSE construction, this G 1/8 machine tap cuts precise BSPP internal threads in tough steels and stainless alloys.

Overview

Engineered to DIN 5156C, this right-hand machine tap produces G 1/8 parallel pipe threads with a 2–3 thread lead chamfer. The cobalt-enriched HSSE substrate withstands high cutting temperatures, while the titanium nitride coating reduces friction and extends tool life. Three flutes ensure efficient chip evacuation in through and blind holes.

What stands out

• TiN coating lowers torque and resists built-up edge.
• HSSE cobalt steel handles abrasive and work-hardening materials.
• Form C chamfer eases thread starting and alignment.
• Compact 63 mm overall length fits standard tap holders.
