Accupro 12183112 Corner Radius End Mill 5/8 in 4 Flute

Product Description

The ACCUPRO 12183112 is a solid carbide corner radius end mill designed for precision milling operations in metal and hard-material applications. With a 5/8 inch diameter and a 0.06 inch corner radius, it produces smooth, radiused inside corners while reducing stress concentration in machined parts. The 4-flute, right-hand spiral configuration supports efficient chip evacuation and a stable cut. At 4-5/8 inches overall length with a 2.0 inch length of cut, this is a long-reach tool suited to deeper cavity work. The bright, uncoated finish makes it a versatile choice for a range of workpiece materials without coating-specific limitations.

This end mill is used in CNC machining centers and manual knee mills for profiling, slotting, and contouring where a radiused corner is required on the finished part. The centercutting design allows plunge entry, adding flexibility in toolpath programming. It is typically installed by machinists and CNC operators in job shops, tool rooms, and production machining environments. The long flute length makes it particularly applicable when workpiece geometry or fixturing requires extended reach into pockets or slots.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance in demanding cuts
• 0.06 inch corner radius reduces stress risers and improves surface finish at inside corners
• 4 right-hand spiral flutes with right-hand cutting direction for standard CNC spindle compatibility
• Centercutting design permits direct plunge entry without a pre-drilled pilot hole
• Long flute type at 2.0 inches length of cut supports deep pocket and cavity milling
• Bright, uncoated finish for broad material compatibility without coating interaction concerns

Compatibility

Designed as a direct-mount solid carbide end mill for standard 5/8 inch collets, end mill holders, and shrink-fit toolholders used in CNC machining centers and conventional mills requiring a corner radius end mill.

Installation Notes

Install in a clean, properly sized collet or end mill holder and torque to holder manufacturer specifications to prevent tool pullout. Verify runout after installation using a dial indicator before cutting. Always set spindle speed and feed rate per material cutting data for solid carbide tooling. Inspect the cutting edges for chipping before each use and do not exceed the stated length of cut depth during profiling passes.
