Accupro G8C2602406 Corner Radius End Mill 3/8 in 4 Flute

Product Description

The ACCUPRO G8C2602406 is a single-end corner radius end mill designed for precision milling operations in metal fabrication and machining environments. Constructed from nanograin solid carbide, it delivers high wear resistance and edge retention on ferrous and non-ferrous workpiece materials. The tool features a 3/8-inch mill diameter, a 3/32-inch (0.0938-inch) corner radius, and 4 straight flutes with right-hand cutting direction. A 1.0-inch length of cut and 0-degree helix angle make this tool well suited to slotting and contouring applications where tool rigidity and controlled chip flow are priorities. Installation and use require a compatible collet chuck or end mill holder sized to the 3/8-inch shank diameter.

This end mill is intended for use in CNC machining centers, knee mills, and manual milling machines by machinists and tooling professionals working in job shops, production facilities, and maintenance machining environments. The extended reach configuration, with a 3/4-inch reach length and a 0.330-inch neck diameter, allows access to features with moderate depth requirements without sacrificing rigidity. The centercutting design permits plunge entry directly into the workpiece, expanding its range of practical applications. The nanograin carbide substrate supports use at higher surface speeds compared to standard carbide grades.

Key Features

• Nanograin solid carbide construction for superior hardness and edge retention
• 3/32-inch (0.0938-inch) corner radius reduces stress concentration at corners and extends workpiece life
• 4 straight flutes with right-hand cutting and right-hand flute direction
• Centercutting design enables direct plunge milling
• Extended reach with 3/4-inch reach length and 0.330-inch neck diameter for deeper feature access
• Mill diameter tolerance of +0.000000 to -0.000800 inches ensures close fitment in precision applications

Compatibility

Designed as an OEM-style replacement or direct tooling selection for standard 3/8-inch collet chucks and end mill holders used in CNC and manual milling setups requiring a corner radius end mill with a straight flute profile.

Installation Notes

This tool should be installed by a qualified machinist or tooling technician using a properly sized collet or end mill holder torqued to the machine manufacturer's specification. Always ensure the spindle is fully stopped and the machine is powered down before changing tooling. Verify runout with a dial indicator after installation, as excessive runout will accelerate wear and compromise corner radius accuracy. Follow the machine manufacturer's feed, speed, and depth-of-cut guidelines for solid carbide end mills at the selected material and diameter.
