Accupro 120662 Roughing End Mill 1/2 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 120662 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from submicron-grade solid carbide, it delivers the rigidity and edge retention needed for high-demand cutting operations. The 1/2 inch diameter tool features three flutes with an integrated chipbreaker geometry that breaks chips into manageable segments, reducing heat buildup and improving chip evacuation. With a 1-1/4 inch length of cut and a 3 inch overall length, it is suited for moderate-depth slotting, pocketing, and profile roughing. Right-hand cutting and spiral flute direction are standard. The bright, uncoated finish works well in a range of ferrous and non-ferrous materials.

This end mill is used in vertical machining centers, CNC milling machines, and manual knee mills where rapid stock removal is the priority before a finish pass. The high helix style promotes efficient chip flow, and the centercutting capability allows plunge entry into workpieces. It is a common choice for tool and die shops, production machining environments, and maintenance machining operations running steel, aluminum, and similar materials at standard cutting parameters.

Key Features

• Submicron solid carbide construction for superior hardness and wear resistance
• Chipbreaker geometry reduces chip load and improves evacuation during heavy cuts
• Centercutting design allows direct plunge entry
• High helix spiral flute promotes efficient chip flow and reduces cutting forces
• 1/2 inch shank with h6 tolerance for consistent tool holder fit
• Bright uncoated finish suitable for a broad range of workpiece materials

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide roughing end mill for standard 1/2 inch tool holders and collet chucks used in CNC and manual milling applications.

Installation Notes

Installation is performed by machinists using a compatible collet chuck, end mill holder, or shrink-fit tool holder rated for 1/2 inch shank tooling. Verify tool holder runout before use, as excessive runout will accelerate edge wear and reduce cutting performance. Ensure the machine spindle is fully stopped and the tool holder is properly torqued before beginning any cut. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth of cut.
