Why choose it

The TiAlN coating provides high hardness and heat resistance, extending tool life even in demanding conditions. The cobalt-alloyed high-speed steel base offers excellent toughness and wear resistance. The spiral point design efficiently evacuates chips forward, reducing clogging and improving thread quality in through holes.

Ideal use cases

• Machine tapping of through holes in steel components
• Threading stainless steel parts in manufacturing
• Creating metric threads in cast iron housings
• Precision tapping in non-ferrous metals and titanium alloys

Good to know

Designed for machine use with a reinforced shank for stable clamping. The Form C chamfer (2-3 threads) provides a good balance of easy starting and thread depth. Suitable for use with emulsion, oil, air, or dry machining conditions.
