Accupro 313483 Square End Mill 3/4 in 2 Flute Carbide Zrn

Product Description

The ACCUPRO 313483 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. Built from micrograin carbide, it delivers wear resistance and edge retention in demanding cutting conditions. The 3/4 inch diameter tool features a 45-degree helix angle and a ZrN (zirconium nitride) coating that reduces friction and extends tool life. With a 3-1/4 inch length of cut and 6 inch overall length, it handles deep-reach slotting, profiling, and side milling. Two right-hand spiral flutes provide efficient chip evacuation. Licensed machinists and CNC mill operators are the primary users of this tool.

This end mill is suited for milling ferrous and non-ferrous metals in both manual and CNC machining environments. The centercutting geometry allows for direct plunge entry into the workpiece, enabling greater flexibility in toolpath programming. The extended 3-1/4 inch length of cut range supports operations requiring reach into deep pockets or along tall workpiece walls. It is appropriate for finishing and semi-finishing passes where dimensional accuracy and surface finish are critical.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• ZrN coating reduces friction and extends cutting tool life
• 45-degree helix angle promotes smooth cutting action and chip flow
• Centercutting design allows direct plunge milling
• Right-hand cut, right-hand flute configuration for standard spindle use
• Tight mill diameter tolerance of +0.000 / -0.002 inches ensures dimensional accuracy

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill compatible with standard 3/4 inch collet or end mill holders on CNC machining centers and manual knee mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Secure the shank fully into the tool holder to the recommended engagement depth before tightening to prevent runout or pullout during cutting. Verify spindle direction is set to right-hand rotation before operation. Inspect the cutting edges and coating condition before each use and remove from service if chipping or coating breakdown is observed.
