Mitsubishi Materials Corporation Metalworking Solutions Division (President: Mirko Merlo, Address: Marunouchi, Chiyoda-ku Tokyo) has announced the addition of the new “ASX300” downsized model to its ASX Series of screw-on insert type shoulder milling cutters. Sales will commence on April 1, 2026.

The ASX Series combines low cutting resistance with excellent fracture resistance, while maintaining stable performance even under high-load machining conditions. This contributes to improved productivity.

The newly developed ASX300 adopts a multi-tooth design enabled by downsizing the inserts. This allows higher table feed rates and shorter machining time. In addition, reduced power consumption contributes to lower CO₂ emissions.

Main features of the ASX300

• Multi-tooth design improves table feed and reduces machining time.
   
• Improved cutting edge design provides high-quality surface finish on walls and faces.
   
• Optimised cutting edge geometry enhances chip evacuation and edge strength.
   
• Controlled load per tooth extends tool life.
   
• Environmentally friendly design reduces environmental impact.

Cutting Performance

• SCM440 finished surface comparison

Achieves a glossy finish without cloudiness.

• Wear resistance comparison of SCM440

The synergistic effect with grade MV1030 dramatically extends tool life under high-speed cutting conditions.
