For the drilling of long and short-chipping materials such as structural and case hardened steels, cast steels, heat-treatable steels and alloyed steels with a tensile strength of up to app. 1200N/mm2, including carbon steels, bronze, cast iron and high alloyed AISi-alloys.
Features and Benefits
High alignment accuracy with small diameter tolerance and excellent surface finish
FIREX coating for increased heat and wear resistance
Self-centring qualities for greater precision
Short chip production due to a concave cutting point geometry and web thinning
Standards
Manufactured to DIN 6537
