Description

Description:

This product is made of high speed steel and cobalt material.

After the complete grinding process, it has stronger cutting ability and a longer service life.

Suitable for processing non-ferrous metals (such as copper and aluminum), non-metallic and ferrous metals (such as iron, steel and stainless steel).

The straight shank works in both keyhole and keyhole chucks.

The advantages of the full grinding drill:

High geometric precision, strong cutting ability.

Smooth surface, long service life.

Wider application range (rough processing, finishing, semi-finish) and comes with edge-free function, processing products have better surface quality.
