CrazyDrill Twicenter is a tungsten carbide centering drill with through tool cooling that exhibits a high degree of precision/process reliability, long tool life and quick machining time when drilling through metal, even in difficult to machine materiales such as stainless, acid-resistant and heat-resistant steels as well as CrCo alloys, titanium and titanium alloys. The possible application in general steels, casting, aluminum, copper, brass, bronze as well as tempered steels extend its operational capability. Consequently, the drill is used very successfully in many applications in the field of micro-precision such as the watch and jewelry industry, medical technology, implants, automotive industry, food industry, tool and die making, mechanical engineering, pneumatics, dental technology, petrochemistry and the aviation industry.
