End Mills for High-Performance Dynamic Milling
Designed for dynamic milling with low radial engagement and full length of cut.
Maximizes capabilities of 5-axis machines, using CAM tool path generation software.

KOR5DA 5xD - For Aluminum
- 5xD length of cut with internal-coolant for a broader application range.
KOR5DA — for Aluminum
- With chip splitters for near-perfect chip management.
- Safe-Lock™ shanks available for pullout protection.
- With and without internal coolant.
KOR5DS — for Steel and Stainless Steel
- With chip deformers for near-perfect chip management at high surface quality.
- Safe-Lock™ and Weldon® shanks for pullout protection.
- 3xD and 5xD with plain and Weldon shanks.
KOR6DT — for Titanium
- With chip splitters for optimized chip management.
- 3xD and 5xD with plain and Weldon shanks.
KOR5 DA High Velocity Aluminum Roughing
- Internal coolant helps flush chips from cutting zone and reduce heat.
- 5 cutting edges enable increased feed rates and high metal removal rates.
- Chipbreakers manage chip removal efficiently.
- Proprietary flute form ensures coolant flow, chip evacuation, and a 3xD maximum depth-of-cut.
- Up to 66% higher table feed in aluminum applications.
- Safe-Lock™ Shank prevents end mill pullout.
