The Decision-Maker's Summary
R1.5 PCD End Mill — The Corner Radius That Changes Production
What Makes This Tool Different
The R1.5 radius at the corner of this PCD end mill serves two functions: it reinforces the edge against impact and chipping, and it produces a controlled fillet on internal corners—eliminating stress risers and manual deburring in one operation.

Why R1.5?
Sharp corners on end mills are stress concentrators. They chip first and fail first. The R1.5 radius spreads cutting forces over a larger area, improving toughness and wear resistance while still allowing square shoulder milling with a designed-in fillet.
