Tungaloy High-Performance Milling Inserts

Double-Sided Economy | Accelerated Metal Removal | AH3135 PVD Technology

Which milling insert provides the best tool life for high-feed roughing and 90° shoulder milling?

The Tungaloy Milling Series (featuring DoForce-Tri, DoPent, and DoOcto technology) represents the pinnacle of indexable milling efficiency. Whether you are performing heavy face milling with ONMU/PNMU or precision shoulder milling with LNMU/APMT, Tungaloy inserts are engineered to handle high-impact loads and rapid chip evacuation. Utilizing the legendary AH3135 grade—a PVD coating specifically optimized for milling stainless steel and difficult-to-cut materials—these inserts resist thermal cracking and chipping. Our milling geometries, such as the -MJ (Medium Roughing) and -ML (Light Cutting), feature high-rake angles that reduce spindle load and minimize vibration during long-overhang operations.

Tech Tip: Milling Tool Life

To prevent thermal cracking, try to avoid coolant during high-speed milling of steels unless you have high-pressure through-spindle cooling. Dry milling with air blast is often better for **CVD-coated milling inserts**. **BEYOND CNC** - Excellence in Tooling.
