Accupro 12179027 Square End Mill 1/32 in 4 Flute Carbide

Product Description

The ACCUPRO 12179027 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. With a 1/32 inch (0.0312 inch) cutting diameter and a 4-flute spiral geometry at a 30-degree helix angle, this tool delivers clean, accurate cuts in tight-tolerance applications. The AlTiN coating improves heat resistance and extends tool life in harder workpiece materials. Center-cutting capability allows direct plunge entry without pre-drilling. This end mill is sized for micro-machining work and is handled by machinists and toolroom operators using CNC mills and manual knee mills.

This end mill suits applications requiring precise detail cuts, slots, and profiles at small diameters. The 1/8 inch shank diameter fits standard ER collet chucks and small-bore tool holders common in CNC machining centers. The regular-length body, 1/8 inch length of cut, and 1-1/2 inch overall length make it well suited for shallow-pocket and fine-feature work in mold making, medical component machining, and precision prototype production.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance at small diameters
• AlTiN finish for elevated heat resistance in dry or semi-dry cutting conditions
• 4-flute spiral geometry with 30-degree helix angle for efficient chip evacuation
• Center-cutting design allows direct plunge milling without a pilot hole
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• Mill diameter tolerance of +0.0002 / -0.0008 inches for consistent fitment and cut accuracy

Compatibility

Designed for use in CNC machining centers and manual mills equipped with 1/8 inch collet chucks or compatible small-bore tool holders. Fits standard ER-style collet systems accepting a 1/8 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Confirm collet runout is within acceptable tolerance before operation, as runout is especially critical at small cutting diameters. Follow the machine manufacturer and tooling supplier recommendations for feed rate, spindle speed, and depth of cut.
