Description

Jobber drill with cyl. shank Design: Angle of rake larger than normal (35°) core thickness. Core thickness thicker than normal, therefore very robust and flexible use. Sturdy, powerful model, profile grinding, right cutting, with precision ground point as well as special point thinning and excellent thermal resistance. Normal core gradient. Application: For use for short drilling depths up to 3 x D. Especially for use for titanium and titanium alloys, for stainless, acid and heat resistant as well as austenitic steels, for high strength and short chipping steels from 900 N/mm² strength as well as for special alloys like Hastelloy®, Inconel® and Nimonic®.
