Accupro 12176880 Corner Radius End Mill 0.0313 in 4 Flute Altin

Product Description

The ACCUPRO 12176880 is a solid carbide corner radius end mill designed for precision milling of ferrous and non-ferrous metals in CNC machining centers and manual mills. At 0.0313 inches in diameter with a 0.005 inch corner radius, this tool is built for fine-feature work where edge integrity and tight tolerances matter. The 4-flute geometry combined with an AlTiN coating supports higher surface speeds and elevated temperatures without sacrificing tool life. The micrograin carbide substrate provides the hardness and wear resistance required for production environments.

This end mill is suited for high-precision slot milling, profiling, and contouring operations on hardened steels, stainless, and similar materials. The single-end, centercutting design allows plunge entry and full-slot cutting in confined areas. With a 3/32 inch length of cut and a 1/8 inch shank, this tool fits standard collet systems and is well-matched to small-format machining work including mold and die detail work, medical component machining, and aerospace part finishing.

Key Features

• 0.005 inch corner radius reduces stress concentration and extends tool life at workpiece edges
• AlTiN coating provides oxidation resistance and hardness at elevated cutting temperatures
• Micrograin solid carbide substrate delivers consistent edge sharpness across the cut
• 4-flute spiral design balances chip evacuation with surface finish quality
• Centercutting geometry enables direct plunge entry without a pilot hole
• Right-hand cut and right-hand flute direction for conventional CNC spindle use

Compatibility

Designed as an OEM-style replacement and standard-fit cutting tool for CNC machining centers and manual mills using 1/8 inch collets or compatible toolholders. No specific machine model compatibility data was provided in the product input.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the 1/8 inch shank fully in a clean, undamaged collet and torque the collet nut to the toolholder manufacturer specification. At 0.0313 inches in diameter, this tool is sensitive to runout — verify TIR with an indicator before initiating a cut, as excessive runout will cause premature breakage.
