Accupro 14796227 Corner Radius End Mill 0.0312 in 3 Flute

Product Description

The ACCUPRO 14796227 is a miniature solid carbide corner radius end mill designed for precision milling operations requiring tight tolerances and fine detail work. With a 0.0312 inch cutting diameter and a 0.0050 inch corner radius, this tool produces clean, radiused edges on hardened and difficult-to-machine materials. The three-flute, right-hand spiral geometry with a 30 degree helix angle promotes efficient chip evacuation while maintaining rigidity in the cut. It is a centercutting, single-end tool suitable for plunge entry, slotting, profiling, and contouring in tight-tolerance machining applications. Machinists and tooling professionals in CNC milling environments are the primary users.

This end mill is built for miniature and micro-scale machining applications where dimensional accuracy is critical. The extended reach design, with a reach length of 0.1560 inches and a length of cut of 0.0460 inches, allows access to confined features and stepped pockets. The 1/8 inch shank diameter is compatible with standard miniature tool holders and collet chucks. It is well suited for mold and die work, medical component machining, electronics fixtures, and aerospace detail parts where small-diameter tooling and tight tolerances are required.

Key Features

• 0.0312 inch cutting diameter with a 0.0050 inch corner radius for precise radiused edge geometry
• Solid carbide micrograin construction provides hardness and wear resistance in demanding materials
• Three right-hand spiral flutes with 30 degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry without pre-drilling
• Extended reach geometry with 0.1560 inch reach length for access to confined features
• Bright/uncoated finish suitable for a wide range of base materials without coating compatibility concerns

Compatibility

Designed as an OEM-style miniature end mill for use with standard 1/8 inch collet chucks and miniature tool holder systems compatible with single-end corner radius tooling.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine control in a safe, locked-out state. Ensure the 1/8 inch shank is fully seated and properly torqued in the collet or tool holder per the holder manufacturer specifications before operation. Inspect the cutting edges under magnification prior to use, as miniature carbide tooling is brittle and susceptible to chipping if mishandled. Run-out should be verified with a dial indicator after tool setup to confirm concentricity within acceptable tolerance for the application.
