Accupro 120656 Roughing End Mill 5/16 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 120656 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 wear resistance required for high-demand cutting operations. The chipbreaker geometry along its three spiral flutes breaks chips into shorter segments, reducing heat buildup and improving chip evacuation during deep cuts. The bright, uncoated finish is suited for a wide range of ferrous and non-ferrous materials. With a 5/16-inch diameter and a 3/4-inch length of cut, this tool fits standard milling setups in both manual and CNC machining environments. Machinists and tool-and-die professionals select this end mill for roughing passes where material removal rate matters.

This end mill is intended for roughing operations in vertical and horizontal milling machines as well as CNC machining centers. The right-hand cutting direction and right-hand spiral flute configuration make it compatible with standard spindle rotation. The high-helix style promotes efficient chip flow and helps maintain cooler cutting temperatures during prolonged cuts. The 5/16-inch shank diameter matches the cutting diameter, allowing direct installation in standard collets or end mill holders without a reducer. It is a practical choice for job shops, tool rooms, and production environments where roughing passes precede finish operations.

Key Features

• Submicron-grade solid carbide construction for superior hardness and wear resistance
• Chipbreaker geometry breaks chips to reduce heat and improve evacuation
• Three spiral flutes with high-helix style for efficient chip flow
• Right-hand cutting and right-hand flute direction for standard spindle use
• Centercutting capable, allowing plunge entry into workpieces
• Bright, uncoated finish suitable for dry cutting and a broad range of materials

Compatibility

Designed as an OEM-style roughing end mill for use in standard collets and end mill holders accepting a 5/16-inch shank diameter in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is powered off before inserting or removing any end mill. Seat the shank fully into the collet or holder to the recommended engagement depth before torquing the retention hardware. Confirm runout with a dial indicator before beginning a cut, as excessive runout will accelerate tool wear and reduce surface quality.
