Accupro 313543 Square End Mill 1 in 2 Flute Solid Carbide Zrn

Product Description

The ACCUPRO 313543 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining environments. It features a 1-inch cutting diameter, a 3.5-inch length of cut, and a 6-inch overall length, making it well suited for deep-reach profiling and slotting applications. The micrograin carbide construction provides hardness and edge retention at elevated cutting speeds. A ZrN (zirconium nitride) coating reduces friction and extends tool life in ferrous and non-ferrous materials. This tool is installed and operated by machinists and CNC tooling professionals.

This end mill is intended for use in vertical machining centers, CNC mills, and manual knee mills requiring a 1-inch shank. The 45-degree helix angle promotes efficient chip evacuation and smooth cutting action during peripheral and slot milling. The centercutting geometry allows plunge entry directly into the workpiece. With a right-hand cut and right-hand spiral flute configuration, it is compatible with standard spindle rotation on most milling equipment.

Key Features

• 1-inch cutting diameter with a mill diameter tolerance of +0.000 / -0.002 inches
• 3.5-inch length of cut for extended reach profiling and deep slot milling
• Micrograin solid carbide construction for hardness and wear resistance
• ZrN coating reduces friction and improves tool life across a range of workpiece materials
• 45-degree spiral helix angle promotes chip evacuation and reduces cutting forces
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut, right-hand flute — compatible with standard CNC and manual mill spindle rotation

Compatibility

Designed as a standard 1-inch shank square end mill for use in milling machines and machining centers that accept 1-inch toolholders, collet chucks, or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully into the toolholder to the recommended gauge-line depth and verify runout before cutting. Power down and lock out the spindle before changing tooling. Follow the machine manufacturer and toolholder specifications for clamping torque and stick-out limits.
