Twisting drill, cylindrical shank
Design: stable, durable drill, right-cutting, precise top grinding and very high heat resistance.
Application: designed in particular for stainless steels, acid-resistant, heat-resistant and austenitic, for hard and short-chip steels with a strength of 900 N/mm2, for special alloys such as Hastelloy®, Inconel® and Nimonic®.
Lateral approach angle greater than normal (38°). Core thickness normal.
