Accupro 314476 Square End Mill 1/8 in 3 Flute Carbide

Product Description

The ACCUPRO 314476 is a solid carbide square end mill designed for precision milling of ferrous and non-ferrous materials in CNC machining and manual milling applications. It carries a 1/8 inch cutting diameter with a 3/4 inch length of cut, a 37-degree helix angle, and a 3-flute spiral geometry. The micrograin carbide substrate provides the hardness and edge retention needed for tight-tolerance work. The bright, uncoated finish makes this tool well suited for applications where coating compatibility is a concern or where base carbide performance is preferred. This tool is installed and operated by machinists and tool-and-die professionals in job shop and production environments.

This end mill is used in small-diameter slotting, profiling, and contouring operations on CNC machining centers and manual knee mills. The 1/8 inch shank diameter fits standard collets and end mill holders designed for that bore size. The 3-flute configuration balances chip evacuation with tool rigidity at this diameter, making it suitable for cutting aluminum, brass, steel, and similar materials where a small-diameter tool path is required. The right-hand cutting and right-hand flute direction are standard for conventional CNC spindle rotation.

Key Features

• Solid micrograin carbide construction for high hardness and edge retention
• 37-degree right-hand spiral helix for efficient chip evacuation
• 3-flute design balances cutting efficiency with rigidity at 1/8 inch diameter
• Center-cutting geometry allows plunge entry as well as peripheral cuts
• Bright, uncoated finish suitable for dry cutting or use with standard cutting fluids
• Single-end configuration with consistent shank and cutting diameter at 1/8 inch

Compatibility

Designed as a direct-fit replacement or standard tooling selection for any milling setup using a 1/8 inch collet or end mill holder with right-hand spindle rotation.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Secure the shank fully into the collet or end mill holder to the recommended engagement depth before tightening. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Do not exceed the tool's rated depth-of-cut for the material being machined.
