Accupro 125630 Roughing End Mill 3/4 in 3 Flute Solid Carbide

Product Description

The ACCUPRO 125630 is a single-end roughing end mill designed for aggressive material removal in milling operations. Built from submicron-grade solid carbide, it delivers the rigidity and wear resistance required for high-feed roughing passes on ferrous and non-ferrous materials. The chipbreaker geometry along its three spiral flutes breaks chips into shorter segments, reducing recutting and heat buildup during heavy cuts. With a 3/4-inch cutting diameter and 2-1/2-inch length of cut, this tool suits deep-pocket and profile roughing where chip evacuation is critical. It is installed by machinists and CNC operators in job shop and production environments.

This end mill is suited for roughing applications in vertical machining centers, horizontal mills, and manual knee mills where the spindle accepts a 3/4-inch straight shank with h6 tolerance. The right-hand cutting direction and right-hand spiral flute configuration match standard CNC and manual milling setups. The high helix style promotes efficient chip flow out of the cut zone, making it well-suited for slotting, pocketing, and peripheral roughing in both light and medium-duty production runs.

Key Features

• Submicron solid carbide construction for high rigidity and extended tool life
• Chipbreaker geometry on 3 flutes reduces chip length and recutting in deep passes
• High helix, right-hand spiral flute for efficient chip evacuation
• Center-cutting capable — supports plunge entry without a pre-drilled hole
• Bright/uncoated finish suitable for a broad range of workpiece materials
• 3/4-inch shank diameter with h6 tolerance for precise collet and chuck fit

Compatibility

Designed as an OEM-style replacement or direct tooling option for standard 3/4-inch straight-shank tool holders, collet chucks, and end mill adapters used in CNC and manual milling applications.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully powered down and locked out before installing or removing the end mill from its holder. Seat the shank fully into the collet or holder to the recommended engagement depth before tightening. Verify runout with a dial indicator after clamping and before initiating a cut, as excessive runout accelerates wear on solid carbide tooling.
