Accupro 313356 Square End Mill 1/2 Inch 2 Flute Solid Carbide

Product Description

The ACCUPRO 313356 is a solid carbide square end mill designed for precision milling operations across a wide range of materials. It features a 1/2 inch cutting diameter, a 4 inch length of cut, and an 8 inch overall length, making it well suited for deep-pocket and long-reach applications. The 2-flute geometry combined with a 45-degree helix angle promotes efficient chip evacuation and smooth cutting action. A ZrN (zirconium nitride) coating improves surface hardness and heat resistance, extending tool life in demanding cutting environments. This end mill is used by machinists and toolroom professionals working on CNC machining centers and manual mills.

This end mill is intended for general-purpose and production milling in metalworking and fabrication shops. The centercutting capability allows plunge cutting as well as peripheral and slot milling. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC vertical machining center setups. Its micrograin carbide substrate supports higher feed rates and improved surface finish compared to standard-grain carbide tooling. The 1/2 inch shank diameter fits standard ER and side-lock toolholders commonly used in job shops and production environments.

Key Features

• Solid micrograin carbide construction for improved wear resistance and edge retention
• ZrN coating increases surface hardness and reduces heat buildup at the cutting edge
• 45-degree helix angle promotes efficient chip evacuation during deep cuts
• Centercutting design allows direct plunge entry without pre-drilling
• 2-flute configuration provides clearance for chip removal in slotting and profiling
• Right-hand cut, right-hand spiral flute for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct-use tooling for CNC vertical machining centers and manual mills accepting a 1/2 inch shank end mill with standard ER collet or side-lock toolholders.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank to the specified clamping torque for the toolholder type in use per the toolholder manufacturer guidelines. Verify runout with a dial indicator after seating to maintain tolerances within the mill diameter tolerance of +0.000 / -0.002 inches.
