Accupro 312904 Square End Mill 1/8 in 2 Flute Carbide

Product Description

The ACCUPRO 312904 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 1/8 inch cutting diameter and a 45-degree helix angle, it delivers efficient chip evacuation and clean cutting action in a compact form factor. The 2-flute, right-hand spiral configuration handles slotting, profiling, and peripheral milling operations. Micrograin carbide construction provides the hardness and wear resistance needed for ferrous and non-ferrous materials. This is a single-end, center-cutting tool, meaning it can plunge as well as cut laterally. Licensed machinists and CNC operators working in job shops or production environments are the primary users.

This end mill suits light-duty to medium-duty milling work where a small-diameter tool is required. The 5/16 inch length of cut and 1-1/2 inch overall length make it well suited for shallow slots and contour work on small workpieces or in tight clearance situations. The bright, uncoated finish makes it a straightforward general-purpose option where specialized coatings are not required. It fits standard 1/8 inch collets and tool holders common on CNC mills, manual mills, and high-speed spindles.

Key Features

• Solid micrograin carbide construction for hardness and extended tool life
• 45-degree helix angle promotes smooth cutting action and efficient chip removal
• Center-cutting design allows direct plunge entry into the workpiece
• Right-hand cut, right-hand flute spiral for use in standard CNC and manual mill setups
• Bright, uncoated finish suitable for general-purpose milling on a variety of materials
• Tight shank diameter tolerance of +0.0001 inches to -0.0004 inches for secure tool holding

Compatibility

Designed as a general-purpose replacement or stock end mill for any machine tool accepting a 1/8 inch shank collet or end mill holder. Compatible with CNC machining centers, manual knee mills, and high-speed rotary spindles set up for 1/8 inch tooling.

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 shank fully in the collet or tool holder and torque the drawbar or collet nut to the machine manufacturer specification. Verify runout with a dial indicator before beginning a cut, especially when working to tight tolerances at this diameter.
