Accupro 14797459 Ball End Mill 0.0312 in 3 Flute Carbide

Product Description

The ACCUPRO 14797459 is a solid carbide ball end mill designed for precision milling of contoured surfaces, slots, and complex 3D profiles in ferrous and non-ferrous materials. At 0.0312 inches (1/32 inch) diameter with a 0.375 inch length of cut, this miniature single-end tool is built for fine detail work where tight tolerances are critical. The micrograin carbide substrate supports edge sharpness and wear resistance at small diameters. Three right-hand spiral flutes with a 30-degree helix angle promote chip evacuation and reduce heat buildup during high-speed passes. This tool is sold individually and suited for machinists and tool-and-die professionals running CNC mills or manual machines requiring small-diameter ball-nose geometry.

This miniature ball end mill is appropriate for precision machining operations in mold making, die work, engraving, and detailed contouring tasks. It fits applications where a standard-size end mill cannot access tight radii or fine features. The 0.375 inch length of cut combined with a 2.5 inch overall length on a 0.125 inch shank makes it compatible with collet systems accepting 1/8 inch shanks, commonly found in CNC machining centers, routers, and manual knee mills used in job shops and prototype work.

Key Features

• 0.0312 inch (1/32 inch) ball nose diameter for fine detail and contour milling
• Solid micrograin carbide construction for edge retention at miniature diameters
• 3 right-hand spiral flutes with 30-degree helix angle for efficient chip evacuation
• Bright uncoated finish suitable for use with or without cutting fluid
• Single-end design with 2.5 inch overall length and 0.125 inch shank diameter
• Mill diameter tolerance of +0.0000 to -0.0010 inches for consistent fitment

Compatibility

Designed as a miniature single-end ball end mill for use in 1/8 inch collet systems on CNC machining centers, CNC routers, and compatible manual milling machines requiring small-diameter ball-nose tooling.

Installation Notes

Installation is performed by qualified machinists following standard tooling change procedures. Ensure the machine spindle is fully stopped and powered down before inserting or removing the tool from the collet. Verify collet size matches the 0.125 inch shank diameter and that the collet and nut are clean and undamaged before tightening. Inspect the cutting edge under magnification before use, as miniature carbide tools are susceptible to edge chipping if mishandled.
