Accupro 316113 Square End Mill 3/4 in 5 Flute Solid Carbide

Product Description

The ACCUPRO 316113 is a solid carbide square end mill designed for precision material removal in ferrous and non-ferrous machining applications. Built with five spiral flutes and a 37-degree helix angle, it delivers efficient chip evacuation and smooth cutting action at moderate to high feed rates. The ZrN (zirconium nitride) coating reduces friction and extends tool life in abrasive materials. With a 0.75-inch mill diameter, a 2.25-inch length of cut, and a 5-inch overall length, this end mill suits deep-reach profiling and slotting operations where rigidity and edge retention are critical. Micrograin carbide substrate supports tight tolerance work across a range of workpiece materials.

This end mill is suited for milling operations in job shop, production, and tool-and-die environments. The centercutting geometry allows plunge entry directly into the workpiece, making it effective for pocketing and ramping applications. Right-hand cut and right-hand flute direction are standard for conventional CNC machining center setups. The 0.75-inch shank diameter fits standard CAT, BT, HSK, and collet-style toolholders used on vertical and horizontal machining centers.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• ZrN coating reduces friction and extends tool life in abrasive cuts
• 5-flute spiral design improves surface finish and feed-rate capacity
• 37-degree helix angle promotes efficient chip evacuation
• Centercutting geometry enables direct plunge and ramping entry
• Right-hand cut and right-hand flute for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct-fit tooling option for CNC machining centers and manual mills accepting a 0.75-inch shank diameter in standard collet, CAT, BT, or HSK toolholding systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify shank-to-holder runout with a dial indicator after seating to stay within application tolerance requirements. Follow machine manufacturer torque specifications for drawbar and collet nut tightening.
