Accupro 95168470 Corner Radius End Mill 5/8 in 4 Flute

Product Description

The ACCUPRO 95168470 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hard materials. It features a 5/8 inch cutting diameter with a 0.0250 inch corner radius that reduces stress concentrations at the base of milled features, extending tool and workpiece life. The 4-flute, right-hand spiral geometry provides efficient chip evacuation and a stable cut. An AlTiN coating delivers high heat resistance and hardness, making this end mill well suited for aggressive cutting conditions where tool temperatures run high. Machinists and tool-and-die professionals are the primary users of this tool.

This end mill is used in CNC machining centers for profiling, slotting, and contouring operations where a controlled corner radius is required on finished part geometry. The centercutting design allows plunge entry directly into the workpiece. The regular length configuration with a 1-5/8 inch length of cut and 3-1/2 inch overall length fits standard toolholders and works in both vertical and horizontal machining setups. It is appropriate for production runs and prototype work on steel, stainless steel, and high-temp alloys where the AlTiN coating provides a thermal barrier.

Key Features

• 0.0250 inch corner radius reduces notch stress and extends part finish quality
• AlTiN coating provides oxidation resistance and hardness at elevated cutting temperatures
• 4-flute right-hand spiral geometry balances chip clearance with surface finish
• Centercutting capability allows direct plunge entry without a pilot hole
• Micrograin solid carbide construction maintains edge integrity under high feed rates
• Variable helix reduces harmonic chatter during extended cuts

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for CNC machining centers accepting a 5/8 inch shank diameter toolholder.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle and toolholder are fully powered down and locked out before changing tooling. Seat the 5/8 inch shank fully into a collet or end mill holder and torque the retention mechanism to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a production cut.
