Description

Description:

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

After the full grinding process, it has a stronger cutting capacity and a longer service life.

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

The straight shaft works in both keyhole and keyhole chucks.

The advantages of the solid grinding drill:

High geometric precision, strong cutting ability.

Smooth surface, long service life.

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