Accupro 12183590 Corner Radius End Mill 5/8 in 4 Flute

Product Description

The ACCUPRO 12183590 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. It features a 5/8 inch mill diameter, a 2 inch length of cut, and a 0.09 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding applications. With 4 flutes and a 40-degree helix angle, it delivers efficient chip evacuation and smooth surface finishes. The bright/uncoated finish suits a wide range of ferrous and non-ferrous materials. This is a single-end, centercutting tool, meaning it can plunge directly into the workpiece. It is installed and operated by machinists and CNC tooling professionals.

This end mill is suited for use in vertical machining centers, CNC milling machines, and manual knee mills where a long-reach, high-flute-count corner radius tool is required. The 6 inch overall length and 5/8 inch shank diameter make it appropriate for setups requiring extended reach into deep pockets or tall workpiece features. The right-hand cutting direction and right-hand flute spiral are standard for conventional and climb milling on CNC equipment. It is applicable in job shops, aerospace component machining, die and mold work, and general precision machining.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance in high-speed applications
• 0.09 inch corner radius reduces edge chipping and improves part surface finish at floor-to-wall transitions
• 40-degree helix angle promotes efficient chip evacuation and reduces heat buildup during cut
• Centercutting design allows direct plunge entry without pre-drilling
• Single-end, right-hand cut with right-hand spiral flutes for standard CNC milling setups
• Bright/uncoated finish compatible with a broad range of workpiece materials

Compatibility

Designed as a direct-fit tooling option for CNC machining centers and manual milling machines accepting a 5/8 inch shank diameter collet, end mill holder, or equivalent toolholder.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholder torque and runout procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Verify shank engagement depth meets the toolholder manufacturer minimum before securing. Confirm spindle direction is set to right-hand rotation before beginning any cut.
