| Range of applications |
A high performance twist drill offering a wide range of applications. Especially suitable for drilling steel with a tensile strength of up to 1000 N/mm˛, cast iron and AlSi-alloys up to approx. 5 x D. The wave grind increases drill performance, improves coolant supply, reduces cutting pressure and encourages chip breaking. The MOVIC-coat is a strong lubricant. MOVIC assists in reducing coolant volume and minimizing built edges. |
