Walter Prototyp Paradur® HT

The Walter Prototyp Paradur® HT high performance tap facilitates the reliable creation of blind hole threads, even in long-chipping, high-strength materials up to 4 x d. The secret lies in the special flute geometry of the Prototyp Paradur® HT, whereby the chips are broken down and transported efficiently out of the thread by the internal coolant supply.

Facts and advantages:
- high degree of process reliability, even when working with deep threads
- typical areas of use: automotive industry (camshafts, crankshafts, connecting rods), large thread dimensions (general mechanical engineering, transmission shafts, casings, etc.)
