Accupro 313826 Square End Mill 1/4 in 2 Flute Carbide Zrn

Product Description

The ACCUPRO 313826 is a solid carbide square end mill designed for precise milling operations in metalworking and machining applications. With a 1/4 inch cutting diameter and a 3/8 inch length of cut, this tool delivers clean, flat-bottomed cuts in ferrous and non-ferrous materials. The micrograin carbide substrate provides the hardness and edge retention required for high-speed milling. A ZrN (zirconium nitride) coating reduces friction and extends tool life in dry or semi-dry cutting conditions. The 45-degree helix angle promotes efficient chip evacuation and reduces cutting forces. Machinists and CNC operators working in job shops, toolrooms, or production environments will find this end mill suited to slotting, profiling, and light plunging operations.

This end mill fits standard 1/4 inch tool holders and collets used on CNC machining centers, knee mills, and manual milling machines. The spiral flute geometry and right-hand cut with right-hand flute configuration are compatible with conventional milling setups. The 4 inch overall length provides adequate reach for most standard workholding setups. It is centercutting, enabling direct plunge entry into the workpiece without a pre-drilled pilot hole.

Key Features

• Micrograin solid carbide construction for hardness and edge retention
• ZrN coating reduces friction and extends tool life in dry cutting conditions
• 45-degree helix angle promotes chip evacuation and reduces cutting forces
• Centercutting geometry allows direct plunge entry without a pilot hole
• Right-hand cut, right-hand flute configuration for standard spindle setups
• Mill diameter tolerance of +0.000/-0.002 inches ensures consistent fit and finish

Compatibility

Designed for use in standard 1/4 inch collets and tool holders on CNC machining centers, knee mills, and manual milling machines capable of accepting a 1/4 inch shank.

Installation Notes

This tool should be installed by a qualified machinist following shop safety protocols. Ensure the spindle is fully powered down and locked out before changing tooling. Verify collet condition and torque the tool holder to the machine manufacturer's specified value using the appropriate wrench. Confirm runout with a dial indicator before beginning a cut, and never exceed the tool's rated length of cut during slotting passes.
