The cobalt alloy speed steel snail drill provides a long life when drilling stainless steel. The two cutting edges and the two grooves quickly remove the chips, which further increases the lifetime of the drill. DIN 338 standard, type N drill (groove), 135 degrees mountain, diameter tolerance H8. Its pointed, cross -tip simultaneously ensures active machining and accurate centralization without displacement.

The cobalt alloy speed steel is made according to DIN 338. The drill stem is N type (groove angle), 135 degrees The tip angle and tolerance of the diameter is H8. Its pointed, cross -tip simultaneously ensures active machining and accurate centralization without displacement.

The drill stem is suitable for machining alloy and unallowed steels, stainless steel, cast iron, steel cast and acid-resistant steel. It has a cylindrical clamp (the diameter of the stem is the same as the drill), can be used in drills and drill/screwdrivers.
