Accupro 95168810 Corner Radius End Mill 1/4 in 5 Flute

Product Description

The ACCUPRO 95168810 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 0.2500 inch mill diameter, a 1.2500 inch length of cut, and a 0.0300 inch corner radius that reduces stress concentrations at the base of milled features. The five-flute geometry increases feed rates compared to standard four-flute tools while maintaining chip clearance. An AlTiN coating provides high heat resistance and oxidation protection, making this end mill well-suited for dry or semi-dry cutting in ferrous and hardened materials. It is a single-end, centercutting tool with right-hand flute direction and right-hand cutting direction.

This end mill is used in CNC machining centers and manual mills where corner radius features, pocketing, slotting, and profiling are required. The long-length configuration with a 4 inch overall length and 45-degree helix angle suits applications that require deeper reach or aggressive material removal. It is intended for use by machinists and tool-and-die professionals working with steel, stainless steel, and other ferrous alloys where AlTiN coating performance is advantageous. Micrograin carbide construction supports tight tolerances and consistent edge retention across production runs.

Key Features

• 0.0300 inch corner radius reduces edge chipping and stress risers in milled pockets
• Five-flute design increases feed capacity over standard four-flute end mills
• AlTiN coating provides high-temperature oxidation resistance for ferrous and hardened materials
• Micrograin solid carbide substrate supports tight tolerances and long tool life
• Centercutting geometry allows plunge entry without a pre-drilled hole
• 45-degree helix angle promotes smooth chip evacuation and reduced cutting forces

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual milling machines accepting a 1/4 inch straight shank end mill.

Installation Notes

Installation is performed by machinists using an appropriate collet or end mill holder rated for the 1/4 inch shank diameter. Confirm shank and collet cleanliness before seating the tool to prevent runout. Follow machine tool manufacturer torque specifications for drawbar or collet nut tightening. Inspect cutting edges before use and replace the tool at first signs of edge wear to maintain dimensional accuracy.
