Accupro 313070 Square End Mill 1/4 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 313070 is a 2-flute solid carbide square end mill designed for precision milling in metal, alloy, and composite workpiece materials. It features a 1/4 inch mill diameter, a 1-1/4 inch length of cut, and a 45-degree helix angle that promotes efficient chip evacuation and smooth cutting action. Built from micrograin solid carbide, this end mill delivers the rigidity and edge retention needed for tight-tolerance work. The bright/uncoated finish makes it well suited for non-ferrous metals and materials where coating adhesion or heat buildup is a concern. This is a single-end, right-hand cutting tool with a right-hand spiral flute configuration.

The 313070 is used in CNC machining centers, knee mills, and manual milling machines across job shops, tool-and-die operations, and general metalworking environments. Its long-length designation, with a 3 inch overall length and 1/4 inch shank diameter, provides extended reach for deeper pockets, slots, and stepped features where a standard-length end mill cannot reach. Centercutting capability allows it to plunge directly into a workpiece. It is installed and operated by machinists and CNC programmers working in precision manufacturing settings.

Key Features

• 1/4 inch mill diameter with a tight tolerance of +0.000 / -0.002 inches for consistent fitment
• Micrograin solid carbide construction for high rigidity and extended tool life
• 45-degree helix angle promotes efficient chip flow and reduces cutting forces
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Right-hand cut and right-hand spiral flute configuration for standard CNC and manual mill setups
• Bright/uncoated finish suited for non-ferrous and light alloy materials

Compatibility

Designed as an OEM-style replacement and standard cutting tool for 1/4 inch collet and end mill holders used in CNC machining centers and manual milling machines requiring a 1/4 inch shank square end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before loading or removing the end mill from the tool holder. Seat the shank fully into the collet or end mill holder to the recommended grip length and tighten to the tool holder manufacturer's specifications. Inspect the cutting edges for chips or wear before each use and replace the tool if edge condition has degraded.
