Walter USA's MU5 double-sided indexable insert Click image to enlargeThe MU5 double-sided indexable insert from Walter USA delivers improved chip breakage and longer tool life.

The insert can be used universally both for steel forged parts and stainless materials in turning operations.

With forged parts, particularly in automotive production, the MU5 positive macro-geometry minimizes crater wear and enables reliable and fully automated production while maintaining a negative clearance.

Other features include an open chip breaker groove for long tool life, a V-shaped chip breaker for improved chip breakage, and a curved cutting edge yielding high surface finish quality.

For copy turning, the MU5 geometry does not just improve chip breakage for turning and facing, but also for chamfers or radii that would otherwise be critical.

The machining parameters of the insert are 0.0006-0.024 in. feed per tooth and 0.020-0.160 in. depth of cut, which applies to 60 per cent of all applications, and the insert is available in all common basic shapes.
