Accupro 95172653 Corner Radius End Mill 3/8 in 4 Flute

Product Description

The ACCUPRO 95172653 is a solid carbide corner radius end mill designed for precision milling in demanding machining environments. Built on the VS Series platform, it features a 3/8 inch diameter with a 0.0150 inch corner radius and a 4-flute configuration for efficient material removal and fine surface finish. The AlCrTiN PVD coating provides high heat resistance and wear protection, making this tool well suited for hard materials and dry or near-dry cutting conditions. The variable index and variable helix geometry reduce harmonic vibration during cutting, improving stability and tool life. Machinists and CNC programmers working in job shops, aerospace, and general metalworking will find this end mill appropriate for finishing and semi-finishing passes.

This end mill is used in vertical and horizontal CNC machining centers where corner radius geometry is required to strengthen the cutting edge and reduce corner chipping. The single-end, centercutting design allows plunge entry and interpolation moves. The long flute designation with a 7/8 inch length of cut and 2.5 inch overall length suits applications requiring reach into pockets or along vertical walls. Right-hand flute direction and right-hand cutting orientation are standard for conventional CNC spindle rotation.

Key Features

• 3/8 inch mill diameter with 0.0150 inch corner radius for edge strength and corner blending
• AlCrTiN PVD coating for high-temperature wear resistance in hard material milling
• Variable index and variable helix geometry reduce chatter and vibration
• 4-flute, single-end, centercutting design allows plunge and slot entry
• Micrograin solid carbide substrate for rigidity and dimensional stability
• Straight-cylindrical shank with h6 shank diameter tolerance for precise toolholder fit

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for CNC machining centers accepting a 3/8 inch straight-cylindrical shank with h6 tolerance. Part of the ACCUPRO VS Series long-length end mill family.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Verify spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully into a compatible collet or end mill holder and torque the retention mechanism per the toolholder manufacturer specification. Confirm runout at the tool tip does not exceed the rated TIR maximum of 0.0037 inches before beginning a cut.
