Accupro 125959 Roughing End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 125959 is a solid carbide roughing end mill designed for aggressive material removal in milling applications. Built with three flutes and a variable pitch configuration, it incorporates a chipbreaker geometry along the cutting edges to break chips into smaller segments, reduce cutting forces, and manage heat buildup during heavy cuts. The 0.09 inch corner radius adds edge strength and helps extend tool life in demanding operations. Manufactured from submicron-grade solid carbide, this tool delivers the rigidity and wear resistance required for high-feed roughing passes on ferrous and non-ferrous workpiece materials.

This end mill is suited for use in CNC machining centers and manual knee mills where roughing passes precede finishing operations. The 1/2 inch mill diameter and 5/16 inch straight cylindrical shank make it appropriate for standard collet and end mill holders. With a 1.25 inch length of cut and 3 inch overall length, it handles moderate-depth pocketing, slotting, and peripheral roughing in shop environments ranging from job shops to production machining. Center-cutting capability allows it to be plunged directly into the workpiece.

Key Features

• Submicron-grade solid carbide construction for superior hardness and wear resistance
• Chipbreaker geometry reduces cutting forces and improves chip evacuation
• Variable pitch flutes minimize harmonic vibration during heavy roughing
• 0.09 inch corner radius strengthens cutting edge and extends tool life
• Center-cutting design enables direct plunge entry into workpiece
• Right-hand cut and right-hand spiral flute configuration for standard spindle operation

Compatibility

Designed as an OEM-style solid carbide roughing end mill compatible with standard collet chucks and end mill holders accepting a 5/16 inch straight cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist with the spindle fully powered down and locked out before tool changes. Secure the shank to the full recommended grip length in the holder to minimize runout and overhang deflection. Verify holder bore tolerances against the h6 shank diameter tolerance before mounting. Follow machine tool manufacturer guidelines and shop-specific feeds and speeds for solid carbide tooling.
