Accupro 12176647 Corner Radius End Mill 0.2188 in 3 Flute

Product Description

The ACCUPRO 12176647 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. With a 0.2188-inch cutting diameter and a 0.02-inch corner radius, it produces smooth, radiused edges on finished workpiece profiles while reducing stress concentrations at inside corners. The 3-flute geometry balances chip evacuation and surface finish, and the TiCN coating increases surface hardness and lubricity for extended tool life in ferrous and non-ferrous materials. This end mill is installed and used by machinists and CNC operators working in job shops, manufacturing facilities, and production environments.

This tool is suited for side milling, slotting, and profiling cuts in steel, stainless steel, aluminum, and similar materials where a radiused corner is required on the finished part. With a 0.75-inch length of cut, a 2.5-inch overall length, and a 0.25-inch shank diameter, it fits standard end mill holders and collet chucks commonly found on vertical machining centers and manual knee mills. The single-end, centercutting design allows plunge entry in addition to peripheral cuts.

Key Features

• 0.02-inch corner radius reduces stress risers and produces radiused inside corners in a single pass
• 3-flute spiral design balances material removal rate with chip clearance
• TiCN coating improves wear resistance and reduces built-up edge in ferrous materials
• Micrograin solid carbide substrate provides rigidity and dimensional stability
• Right-hand cut and right-hand flute direction suit standard CNC and manual spindle rotation
• Centercutting capability allows direct plunge entry without a pre-drilled hole

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool for standard 0.25-inch collet chucks and end mill holders on vertical machining centers, CNC mills, and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully in the collet or holder to the recommended gauge line depth and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut, as excessive runout accelerates corner radius wear and reduces dimensional accuracy.
