Accupro 95169645 Corner Radius End Mill 1/2 in 4 Flute

Product Description

The ACCUPRO 95169645 is a solid carbide corner radius end mill designed for precision milling operations in metal cutting and machining applications. It features a 1/2 inch diameter with a 0.0300 inch corner radius, delivering controlled edge geometry that reduces stress concentration and extends tool life in demanding cuts. The 4-flute, single-end configuration with a long 1-1/2 inch length of cut provides excellent chip evacuation and rigidity. An AlCrTiN physical vapor deposition (PVD) coating improves heat and wear resistance at elevated cutting speeds. This tool is used by machinists and tool-and-die professionals on CNC machining centers and manual mills.

The 95169645 is suited for profiling, slotting, and contouring operations in ferrous and hardened materials where a radiused corner is required to prevent sharp-corner stress risers. The centercutting design allows plunge entry, giving the operator flexibility in toolpath programming. With variable index and variable helix geometry, it is built to reduce harmonic chatter during long-reach or deep-pocket operations, making it appropriate for production environments where surface finish and dimensional accuracy are critical. The 3 inch overall length fits standard toolholding systems with a 1/2 inch bore.

Key Features

• 0.0300 inch corner radius reduces edge chipping and stress on workpiece corners
• AlCrTiN PVD coating provides elevated temperature and wear resistance for ferrous cutting
• Variable index and variable helix design reduces harmonic vibration and chatter
• Centercutting geometry allows direct plunge entry without a pre-drilled hole
• Micrograin solid carbide substrate delivers consistent hardness and edge retention
• Right-hand cut, right-hand spiral flute direction for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement and production-grade cutting tool for CNC machining centers and manual milling machines accepting a 1/2 inch straight-cylindrical shank. Part of the ACCUPRO VS Series long-length end mill line.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool from the toolholder. Use a calibrated toolholder with the correct 1/2 inch bore and verify runout against the published TIR maximum of 0.0045 inches before initiating a cut. Consult the machine manufacturer and applicable ANSI or ASME machining standards for recommended speeds, feeds, and clamping torque for solid carbide end mills.
