Gear Hobs

Ultra high precision, excellent hobbing performance


Our hobs prove themselves by their enormously long tool life and are thus also capable of extremely productive applications: in comparison with powder-metallurgical steels, carbide hobs can be driven with considerably higher cutting speeds – resulting in drastically lower machining times and ultimately greater economy in the entire process. We are flexible to meet customer tailored need. The breakthrough of soonest 10 days delivery time, it absolutely adapts the high speed development of HSS transferring to carbide material.
