Multi angle profile cutter and automatic centering is the most efficient method to rapidly guarantee a perfect valve job with minimum stock removal. A complete seat profile is achieved in one easy operation and offers consistent seat width and depth.

The SERDI tooling technology has became a standard of the industry throughout the world. Most cylinder head machinery manufacturers are now offering SERDI Style tooling as a standard.

The impact of environmental issues on modern vehicle manufacturing, led car manufacturers to develop low emission, clean burning, high efficiecy engines. This new technology requires extremely hard valve seat material.

- Multi positive rake profile carbide cutter.
- Reduces cutting force by as much as 30%.
- Runs smoother.
- Improves material removal efficency on hard, modern, seat material.
- Well-balanced carbide grade for excellent wear resistance.
- Extended tool life, re-sharpenable cutting edge.

- New precision CAD design, reinforces bit holders and tool holders.
- Advances geometry for unmatched angular accuracy and repeatability.
- New square walled bit pocket for solid clamping, maximized rigifity and increased bit contact surface onto the bit holder.
