Accupro 95169980 Corner Radius End Mill 3/8 in 5 Flute

Product Description

The ACCUPRO 95169980 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. Built on the HS series platform, this single-end, centercutting tool features a 3/8 inch diameter with a 0.0300 inch corner radius and five flutes ground from micrograin carbide stock. An AlCrTiN coating provides thermal resistance and extended tool life when cutting hard alloys, stainless steels, and high-temp materials. The 38 degree helix angle promotes efficient chip evacuation, and a variable index flute spacing reduces harmonic chatter during aggressive cuts.

This end mill is suited for CNC machining centers and manual knee mills handling finish and semi-finish passes in ferrous and non-ferrous materials. The 1-1/2 inch length of cut and 3 inch overall length make it appropriate for moderate-depth pocketing, slotting, and profiling work where a corner radius is required to reduce stress concentration at part features. It is installed and used by machinists, toolroom operators, and CNC programmers in job shops, production facilities, and maintenance machining environments.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlCrTiN coating for high-heat performance in hard and abrasive materials
• 0.0300 inch corner radius reduces stress risers and improves part surface finish
• 5-flute geometry with variable index for chatter suppression and higher feed rates
• Centercutting design allows plunge entry without a pre-drilled hole
• Right-hand cut, right-hand spiral with straight-cylindrical shank for standard collet or end mill holder mounting

Compatibility

Designed as an OEM-style replacement and standard cutting tool for CNC machining centers and manual mills accepting a 3/8 inch straight-cylindrical shank via ER collet, end mill holder, or equivalent tooling system.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Seat the shank to the full recommended insertion depth in the collet or holder and torque the retention mechanism to the toolholder manufacturer's specification. Verify runout with a dial indicator before starting a cut to protect both the tool and the workpiece.
