Description
The OSG Carbide 4 Flute End Mill with a corner radius and TiSlN coating is a precision cutting tool designed for exotic materials. With a 4 mm diameter and a 0.5 mm corner radius, it delivers stable cuts, efficient material removal, and clean pocketing in challenging alloys and composites.
Designed for machinists, engineers, and hobbyists who work with tough materials, this end mill emphasizes durability and reliability—helping you maintain tight tolerances and finish quality even under demanding cutting conditions.
- Four-Flute Design for Efficient Material Removal: The four-flute geometry provides a balance of aggressive chip clearance and cutting stability, enabling higher feed rates and smoother cuts in exotic materials while minimizing heat buildup and improving surface finish.
- Corner Radius R0.5 for Strength and Finish: The 0.5 mm corner radius adds edge strength and helps reduce chipping on corners, producing consistent radii in pockets and smoother finishes on complex geometries.
- TiSlN Coating for Durability and Heat Resistance: The TiSlN coating enhances wear resistance and reduces built-up edge, delivering longer tool life and reliable performance in high-temperature cutting of titanium, stainless steels, and other demanding alloys.
This end mill is a dependable choice when longevity and precision matter. The combination of carbide hardness, optimized flute geometry, corner radius, and protective TiSlN coating supports steady throughput, repeatable results, and confidence across a range of exotic-material milling tasks—from roughing through finishing—so you can complete projects with less downtime and more consistent quality.
