Accupro 12182313 Square End Mill 0.5 in 3 Flute Carbide

Product Description

The ACCUPRO 12182313 is a solid carbide square end mill designed for precision milling operations in metal cutting and machining environments. Built from micrograin solid carbide, it delivers consistent edge retention and dimensional accuracy across a wide range of materials. The 0.5 inch cutting diameter pairs with a 1.5 inch length of cut and a 6 inch overall length, making it well suited for deep-reach applications where a standard-length tool cannot access the workpiece. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. This tool is installed and operated by machinists, tool-and-die makers, and CNC programmers working in production or job-shop environments.

This end mill is used in vertical and horizontal milling operations on CNC machining centers and manual knee mills. The extra-long overall length of 6 inches supports applications requiring extended reach into deep pockets, slots, and contoured features. The centercutting geometry allows plunge milling directly into the workpiece without a pre-drilled pilot hole. Right-hand cut with right-hand spiral flutes makes it compatible with standard spindle rotation on conventional milling equipment. Typical applications include slotting, profiling, and pocket milling in ferrous and non-ferrous metals.

Key Features

• Solid micrograin carbide construction for superior hardness and wear resistance
• 40-degree helix angle for aggressive chip evacuation and reduced heat buildup
• Centercutting design allows direct plunge entry without a pilot hole
• 3 flutes provide a balance between chip clearance and cutting edge strength
• Extra-long 6 inch OAL for deep-reach milling applications
• Uncoated finish suitable for use with cutting fluids across a range of workpiece materials

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard 0.5 inch collet or end mill holder systems on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank in a properly sized collet, end mill holder, or shrink-fit toolholder rated for the 0.5 inch shank diameter before engaging the spindle. Verify runout with a dial indicator before commencing cutting operations. Always confirm spindle direction matches the right-hand cut orientation of this tool before starting the machine.
