The Application-Focused Format
R1.5 PCD End Mill — Designed for Strength, Precision, and Longevity
A 1.5 mm corner radius on a PCD-tipped end mill serves two critical functions: it reinforces the cutting edge at its weakest point, and it generates a controlled fillet at the shoulder—eliminating sharp internal stress risers and the need for manual deburring.

The Engineering Behind the Radius
Why add a radius to a cutting tool? Because sharp 90-degree corners are stress concentration points. Under cutting forces, that sharp corner is the first to chip or fracture. Once the corner fails, the entire edge follows. The R1.5 radius distributes these forces across a curved profile, significantly improving impact resistance and abrasive wear tolerance—all while maintaining the ability to produce a square shoulder.
What this means for production: flat floors, clean vertical walls, and a 1.5 mm fillet that extends tool life while improving part strength.
