Accupro 12183484 Corner Radius End Mill 1/4 in 4 Flute Ticn

Product Description

The ACCUPRO 12183484 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. It features a 1/4 inch mill diameter, a 1 inch length of cut, and a 0.045 inch corner radius that reduces stress concentration at the cutting edge and extends tool life on profiling passes. The TiCN coating adds hardness and wear resistance, making the tool well-suited for ferrous and non-ferrous materials. With 4 flutes and a right-hand spiral flute design, it delivers efficient chip evacuation and a smooth surface finish. This is a single-end, centercutting tool, so it can be plunged directly into the workpiece.

This end mill fits standard CNC machining centers, vertical mills, and manual knee mills equipped with a 1/4 inch collet or end mill holder. It is used in job shops, tool and die operations, and production machining environments where corner radius profiles are required on pockets, slots, or contoured surfaces. The long flute length and 4 inch overall length make it capable of reaching deeper cavities without requiring an extended-reach setup. Machinists and CNC operators working in aerospace, mold making, and general precision machining will find this tool applicable to a wide range of profiling and finishing operations.

Key Features

• 0.045 inch corner radius reduces edge chipping and improves tool life on profiling cuts
• TiCN coating provides enhanced wear resistance and hardness for extended tool life in ferrous materials
• Solid micrograin carbide construction for rigidity and dimensional stability
• 4-flute right-hand spiral design for efficient chip removal and improved surface finish
• Centercutting geometry allows direct plunge entry without pre-drilling
• Single-end design with a 1/4 inch shank for compatibility with standard collets and tool holders

Compatibility

Designed for use in CNC machining centers and manual mills equipped with a 1/4 inch collet or end mill holder accepting a standard straight shank.

Installation Notes

This tool should be installed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet or end mill holder and torque the retention mechanism per the machine tool manufacturer specifications. Verify runout with a dial indicator before commencing cuts, as excessive runout will accelerate wear and compromise corner radius tolerance.
