Accupro 314636 Square End Mill 9/32 in 3 Flute Carbide

Product Description

The ACCUPRO 314636 is a solid carbide square end mill designed for precision milling operations in metal and hard material applications. Built from micrograin carbide and coated with zirconium nitride (ZrN), it delivers extended tool life and reduced heat buildup at the cutting edge. The 9/32 inch (0.2813 inch) cutting diameter and 37-degree helix angle improve chip evacuation and surface finish quality. With a 3-flute, right-hand spiral configuration and center-cutting capability, it handles plunging, slotting, and peripheral milling. Machinists and tool-and-die professionals install this end mill in CNC machining centers and manual mills.

This end mill is suited for finish and semi-finish milling in ferrous and non-ferrous metals, including stainless steel and hardened materials where ZrN coating provides a performance advantage over uncoated tooling. The 13/16 inch length of cut (0.8125 inch) handles moderate-depth passes, and the 5/16 inch shank fits standard collets and end mill holders common in light-duty CNC setups. It is a single-end tool with no chipbreaker and no variable helix, keeping it straightforward for standard milling tasks.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• ZrN (zirconium nitride) coating reduces friction and extends tool life in ferrous materials
• 37-degree helix angle promotes efficient chip evacuation and improved surface finish
• Center-cutting design allows direct plunge entry into workpiece material
• Right-hand cut and right-hand flute spiral for use in standard spindle rotation setups
• Mill diameter tolerance of +0.000 / -0.005 inches for consistent fit and finish results

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for CNC machining centers and manual milling machines accepting a 5/16 inch shank diameter via collet or end mill holder.

Installation Notes

Installation is performed by machinists and toolroom technicians. Power down and lock out the spindle before loading or removing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth before tightening, and verify runout with a dial indicator before the first cut. Always inspect the cutting edges for chips or wear before use.
