Accupro 314672 Square End Mill 5/16 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 314672 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. It features a 5/16-inch diameter cutting edge, a 1-1/8-inch length of cut, and a 37-degree helix angle that promotes efficient chip evacuation and smooth cutting action. Built from micrograin solid carbide, this end mill delivers rigidity and wear resistance suited to demanding cutting conditions. The bright/uncoated finish makes it a versatile choice across a range of workpiece materials. Machinists and CNC operators install this tool in milling machines and machining centers for slotting, profiling, and peripheral milling tasks.

This end mill is suited for use in job shops, tool rooms, and production machining environments handling ferrous and non-ferrous materials. Its 3-flute geometry balances chip clearance with cutting edge strength, making it appropriate for both roughing and semi-finishing passes at moderate feeds and speeds. The right-hand cutting and right-hand flute direction are standard for conventional vertical milling machine and CNC machining center spindles. The 5/16-inch shank diameter fits standard collet chucks and end mill holders in that bore size.

Key Features

• Micrograin solid carbide construction for hardness and dimensional stability under load
• 37-degree helix angle promotes efficient chip flow and reduces cutting forces
• 3-flute design balances chip evacuation with edge strength for slotting and profiling
• Centercutting capability allows plunge entry into the workpiece
• Bright/uncoated finish compatible with a broad range of workpiece materials
• Right-hand cut and right-hand spiral for standard spindle direction

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard 5/16-inch bore collet chucks and end mill holders on vertical milling machines and CNC machining centers.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Power down and lock out the spindle before changing tooling. Seat the 5/16-inch shank fully into the collet or end mill holder and torque the retention hardware to the machine or toolholder manufacturer specification. Inspect the cutting edges for chips or damage before each use; carbide is brittle and should not be used if the edge is compromised.
