Accupro 12179341 Corner Radius End Mill 5/8 in 3 Flute Carbide

Product Description

The ACCUPRO 12179341 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 5/8 inch diameter, a 0.025 inch corner radius, and a 1-1/4 inch length of cut, making it well suited for profiling, slotting, and finishing passes where edge protection and surface quality matter. Manufactured from micrograin solid carbide, it delivers consistent performance in hardened and abrasive workpiece materials. The bright/uncoated finish suits a wide range of general-purpose applications. This tool is installed and operated by machinists and CNC programmers working in job shops, tool rooms, and production environments.

This end mill is appropriate for use on CNC machining centers and manual mills handling ferrous and non-ferrous materials. The single-end, centercutting design allows for both peripheral and plunge cuts. The 40-degree helix angle promotes efficient chip evacuation and smooth surface finishes in profiling and finishing applications. With a 5/8 inch shank diameter matching the cutter diameter, it seats directly in standard collet chucks and end mill holders of the same bore size.

Key Features

• 5/8 inch cutter diameter with matching 5/8 inch shank diameter for direct collet seating
• 0.025 inch corner radius reduces stress concentration and edge chipping at workpiece corners
• 3-flute geometry balances chip load capacity with chip clearance
• Micrograin solid carbide substrate for hardness and wear resistance
• 40-degree right-hand helix promotes efficient chip evacuation and smooth finishes
• Centercutting design allows plunge entry without pre-drilling
• Bright/uncoated finish compatible with a broad range of workpiece materials

Compatibility

Designed as an OEM-style solid carbide corner radius end mill compatible with standard 5/8 inch bore collet chucks and end mill holders used on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling guidelines. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth and torque the retention mechanism per the holder manufacturer's specification. Verify runout with a dial indicator before commencing cuts.
