Accurate blind hole thread cutting

Practical benefits

Efficient upward chip clearance: The spiral flute design guides chips upwards out of the hole, allowing you to tap blind holes cleanly without jamming.
Long-lasting cobalt steel build: Made from resilient HSS-E tool steel, this tap withstands high friction and maintains sharp cutting edges across various metals.
Secure and steady clamping: The reinforced DIN 371 shank with square drive gives you rigid tool holding to prevent slippage during threading operations.

In a nutshell

The right choise for

With the Phantom 23.300 uni HSS-E/V3 machine tap, you cut precise metric M2.5 threads in blind holes without risking chip congestion at the bottom. The spiral flute geometry evacuates chips upward out of the hole during operation, ensuring clean threading with a 0.45 mm pitch up to a 9 mm depth. Built from cobalt-alloyed hss-e tool steel, it delivers superior wear and heat resistance across demanding machining tasks in steel, stainless steel, and other metals. The reinforced din 371 shank with a 2.8 mm diameter and 2.1 mm square drive provides secure, rigid clamping in your tap holder or cnc setup.
