Accupro 313060 Square End Mill 1/4 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 313060 is a single-end square end mill designed for precise milling operations in metal, composites, and other machinable materials. Built from micrograin solid carbide, it delivers rigidity and wear resistance in demanding cutting conditions. The 0.25-inch diameter tool features a ZrN (zirconium nitride) coating that reduces friction and extends tool life at elevated cutting temperatures. With a 45-degree helix angle and spiral flute geometry, the 313060 promotes efficient chip evacuation and smooth cutting action. Licensed machinists and CNC operators working in job shops, toolrooms, and production environments are the primary users of this tooling.

This end mill suits applications requiring a 1-inch length of cut with a 0.25-inch shank, fitting standard 1/4-inch collets and tool holders. Its centercutting capability allows it to plunge directly into a workpiece, making it practical for slot milling, pocket milling, and profiling operations. The right-hand cut and right-hand flute orientation are standard for conventional CNC machining center setups. With a 2.5-inch overall length, the tool provides adequate reach for typical shallow-to-mid-depth features without sacrificing rigidity.

Key Features

• Micrograin solid carbide construction for improved hardness and edge retention
• ZrN coating reduces friction and extends tool life in ferrous and non-ferrous materials
• 45-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Centercutting design enables direct plunge entry into the workpiece
• Right-hand cut, right-hand flute — standard orientation for CNC machining centers
• Mill diameter tolerance of +0.000 / -0.002 inches ensures consistent fit and finish

Compatibility

Designed for use with standard 1/4-inch precision collets and end mill holders on CNC machining centers and manual milling machines that accept 0.25-inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank to the recommended engagement depth in the collet or tool holder and torque the retention mechanism according to the tool holder manufacturer specifications. Inspect the cutting edges for chips or damage before each use.
