Description

Jobber drill with cyl. shank Design: HSS, Co5, DIN 338. Profile grinding, right cutting, with precision ground point and special grinding. Normal core gradient. Angle of rake larger than normal (35°) Normal core thickness. Core thickness thicker than normal, therefore very robust and flexible use. Application: Special drill with extremely high thermal resistance and stable core: very robust and therefore ideally suited for titanium and titanium alloys, for stainless, acid and heat resistant as well as austenitic steels, for high strength and short chipping steels from 1400 N/mm² strength as well as for special alloys like Hastelloy®, Inconel® and Nimonic®.
