Accupro 125962 Roughing End Mill 3 Flute Solid Carbide

Product Description

The ACCUPRO 125962 is a solid carbide roughing end mill designed for aggressive material removal in milling operations. Built with three flutes and a variable-pitch chipbreaker geometry, it breaks up chips to reduce harmonics and lower cutting forces during heavy roughing passes. The 0.045-inch corner radius adds edge strength and helps resist chipping on demanding cuts. With a 5/8-inch mill diameter, a 1.625-inch length of cut, and a 3.5-inch overall length, this tool is sized for standard roughing work on vertical and horizontal machining centers. It is installed by machinists and CNC operators working in job shops, production facilities, and tool rooms.

This end mill suits roughing applications in ferrous and non-ferrous materials where chip control is critical. The submicron carbide grade provides wear resistance and edge retention across extended run times. The bright, uncoated finish makes it a practical choice when coatings are unnecessary or when the workpiece material performs better against bare carbide. It fits straight-cylindrical tool holders with a 5/8-inch bore and is well suited for vertical machining centers running moderate to high spindle speeds.

Key Features

• Chipbreaker geometry reduces chip load and cutting forces during roughing passes
• Variable pitch reduces harmonic vibration and chatter
• Submicron solid carbide construction for edge retention and wear resistance
• 0.045-inch corner radius strengthens the cutting edge and reduces chipping
• Center-cutting capability allows plunge entry into workpieces
• Right-hand cut and right-hand spiral flute direction for standard milling setups
• High helix style promotes chip evacuation and improved surface finish during roughing

Compatibility

Designed as a direct-fit replacement for standard 5/8-inch straight-cylindrical tool holders used in CNC milling applications requiring a single-end roughing end mill with chipbreaker geometry.

Installation Notes

This tool is installed by machinists and CNC operators. Confirm the tool holder bore matches the 5/8-inch shank diameter and meets the h6 shank tolerance spec before installation. Torque the set screw or collet nut to the tool holder manufacturer's specification. Verify spindle runout before beginning roughing passes to protect the cutting edge.
