Description
The OSG Carbide 4 Flute End Mill with Corner Radius is a regular-length, center-cutting tool designed for general machining tasks. With an 8 mm diameter and a 1.5 mm corner radius (R1.5), this four-flute carbide end mill delivers steady, efficient material removal for milling, slotting, and profiling in everyday shop work.
Coated with TiAlN to boost wear resistance and heat tolerance, the tool stays sharper longer and handles tougher cutting conditions with confidence. The R1.5 corner radius provides smoother cuts and cleaner edges, while the four-flute geometry offers stable cutting and reliable performance across a range of general applications.
- Four-flute design for efficient cutting: Delivers stable, productive material removal with strong chip evacuation, helping you complete slots, pockets, and profiles faster while maintaining good surface finish.
- TiAlN coating for durability and heat resistance: Extends tool life by reducing wear and enabling higher cutting speeds, so you spend less time changing tools and more time finishing parts.
- Corner radius of R1.5 for smoother edges: Enables smoother, chatter-free cuts and better surface finishes on corners and profiles, enhancing part quality and reducing edge breakage.
This end mill is a dependable choice for general machining where consistency, durability, and precise corners matter. Its center-cutting capability supports plunge milling, and the TiAlN-coated carbide construction delivers repeatable performance across a wide range of everyday tasks, helping you improve workflow and reduce downtime without compromising accuracy.
