Accupro 314684 Square End Mill 5/16 in 3 Flute Carbide

Product Description

The ACCUPRO 314684 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a 5/16 inch diameter, a 1-1/2 inch length of cut, and a 37-degree helix angle, this tool delivers efficient chip evacuation and smooth cutting performance on a wide range of ferrous and non-ferrous materials. The micrograin carbide construction provides the hardness and edge retention needed for demanding production work. It is a single-end, right-hand cutting tool with a right-hand spiral flute configuration and a bright/uncoated finish. Machinists and CNC operators install this tool in standard collet or end mill holders.

This end mill is suited for slotting, profiling, and peripheral milling operations in job shop and production machining environments. The 3-flute geometry balances chip clearance with cutting edge contact, making it a practical choice for aluminum, steel, and similar materials where tool rigidity and surface finish both matter. The centercutting capability allows plunge entry, adding versatility for interpolated pocketing operations. Overall length is 3-1/2 inches with a 5/16 inch shank diameter matching the cutting diameter.

Key Features

• Solid micrograin carbide construction for edge retention and wear resistance
• 37-degree helix angle promotes efficient chip evacuation and reduced cutting forces
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand cut and right-hand spiral flute direction for standard CNC and manual mill setups
• Bright/uncoated finish suitable for a broad range of general-purpose milling applications
• 3-flute configuration balances chip clearance with cutting surface contact

Compatibility

Designed as a general-purpose replacement or production end mill for use in standard 5/16 inch collet chucks, end mill holders, and compatible milling machine spindles.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully powered down and locked out before changing tooling. Seat the shank fully into the holder to the recommended minimum engagement depth and torque the set screw or collet nut per the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning a cut to protect both the tool and the workpiece.
