Accupro 14796313 Corner Radius End Mill 0.0781in 4 Flute

Product Description

The ACCUPRO 14796313 is a solid carbide corner radius end mill designed for high-precision milling in demanding machining environments. Built on a miniature-series platform, it features a 0.0781 inch mill diameter, a 0.01 inch corner radius, and four spiral flutes with a 30-degree helix angle. The AlTiN coating provides elevated heat resistance and extended tool life in ferrous and hard-alloy cutting applications. The micrograin carbide substrate delivers rigidity and edge retention at small diameters. This tool is installed and operated by machinists and CNC programmers working in tool-and-die, aerospace, medical device, and precision component manufacturing.

This end mill is suited for finishing and semi-finishing passes in tight-tolerance features including slots, pockets, and contoured surfaces at miniature scales. Its centercutting geometry allows plunge entry, and the single-end configuration is standard for CNC machining centers and manual mills equipped with a 1/8 inch collet. The corner radius helps reduce stress concentration at the cutting edge and improves surface finish on workpiece corners. Applications include mold cavity work, prototype machining, and fine-feature profiling on small components.

Key Features

• 0.0781 inch mill diameter with 0.01 inch corner radius for precision edge blending
• AlTiN coating for high-heat resistance and extended tool life in ferrous materials
• Micrograin solid carbide substrate for rigidity and edge retention at miniature scale
• 4-flute spiral design with 30-degree helix for smooth chip evacuation
• Centercutting geometry allows direct plunge entry
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed for use in CNC machining centers and manual mills with a 1/8 inch collet or toolholder. Fits standard ER or precision collet systems accepting a 1/8 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. The machine spindle must be fully stopped and the tool changer or collet system depressurized before changing tooling. Verify collet bore and taper compatibility with the 1/8 inch shank before seating the tool. Follow the machine manufacturer and tool manufacturer guidelines for runout tolerance, stick-out length, and feeds and speeds appropriate to the workpiece material and coating type.
