Accupro 12463391 Corner Radius End Mill 0.06in 4 Flute Carbide

Product Description

The ACCUPRO 12463391 is a solid carbide corner radius end mill designed for high-precision milling in tight-tolerance applications. It features a 0.0600 inch mill diameter with a 0.0150 inch corner radius, producing a controlled edge break or blend radius on machined features. The 4-flute, right-hand spiral geometry paired with an AlTiN coating supports efficient chip evacuation and extended tool life in ferrous and hard materials. At 1.5 inches overall length with a 0.75 inch length of cut and 1/8 inch shank diameter, this miniature end mill fits standard collets and tool holders used in CNC machining centers and manual mills handling small-format work.

This end mill is suited for die and mold work, medical component machining, aerospace detail parts, and any application requiring a small-diameter corner radius profile. Its centercutting design allows plunge entry, giving machinists flexibility in tool paths. The miniature series designation makes it a direct choice when working with fine features, narrow slots, or shallow pocket floors where full-size tooling cannot reach. Licensed machinists and CNC programmers working in job shops or production environments are the primary users.

Key Features

• 0.0150 inch corner radius for precise edge blending and fillet generation
• Solid micrograin carbide substrate for rigidity and wear resistance at small diameters
• AlTiN coating extends tool life in hardened steels and high-temp alloys
• 4-flute right-hand spiral geometry improves surface finish and chip flow
• Centercutting end allows direct plunge and ramp entry
• 1/8 inch shank diameter fits standard miniature collets and toolholders

Compatibility

Designed for use in CNC machining centers and manual mills equipped with 1/8 inch collets or toolholders. Suited for miniature milling applications in ferrous metals, hardened steels, and high-temperature alloys where an AlTiN-coated solid carbide tool is appropriate.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the 1/8 inch shank fully into the collet or toolholder and torque the collet nut to the toolholder manufacturer specification. At this diameter, runout control is critical — verify TIR with a dial indicator before starting a production run.
