Accupro 314600 Square End Mill 1/4 in 3 Flute Carbide

Product Description

The ACCUPRO 314600 is a solid carbide square end mill designed for precision milling operations in metal, alloy, and engineered material applications. With a 1/4 inch mill diameter, a 1 inch length of cut, and a 37-degree helix angle, this tool delivers efficient chip evacuation and smooth cutting action in a range of ferrous and non-ferrous materials. The three-flute geometry balances chip load and rigidity, making it well-suited for profiling, slotting, and contouring passes where accuracy and finish quality matter. The bright uncoated surface finish is appropriate for use where coating-related thermal considerations are a factor.

This end mill is used in CNC machining centers, manual mills, and tool-and-die applications across job shops, production facilities, and maintenance shops. The single-end configuration and right-hand cutting and flute direction are standard for conventional and climb milling setups. The micrograin carbide substrate supports the tight tolerances required in precision component work. Center-cutting capability allows the tool to plunge directly into the workpiece when the operation requires it.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• 37-degree helix angle promotes efficient chip evacuation and reduced cutting force
• Center-cutting design allows direct plunge entry
• Right-hand cut and right-hand spiral flute direction for standard milling setups
• Bright uncoated finish suitable for a broad range of workpiece materials
• Mill diameter tolerance of plus 0.000 / minus 0.005 inches for consistent fit in toolholders

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for 1/4 inch collet and toolholder systems in standard CNC and manual milling machine setups.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 1/4 inch shank fully and evenly in the collet or toolholder before tightening to the torque specification listed in your machine or toolholder documentation. Inspect the cutting edges for chips or wear before each use.
