Accupro 12181466 Corner Radius End Mill 0.5in 2 Flute

Product Description

The ACCUPRO 12181466 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. It features a 0.5 inch diameter, a 0.03 inch corner radius, and a 1 inch length of cut, making it well suited for profiling, slotting, and peripheral milling where a controlled corner radius is required to reduce stress concentrations and extend part life. The micrograin carbide construction provides high hardness and wear resistance across a range of workpiece materials. Machinists and CNC operators install this tool in standard end mill holders or collet chucks. The bright uncoated finish is ready to run as delivered.

This end mill is used in job shops, tool rooms, and production machining environments handling ferrous and non-ferrous materials. It is a single-end, centercutting tool, meaning it can be plunged directly into the workpiece as well as used for conventional peripheral and slot milling passes. The right-hand spiral flute geometry and right-hand cutting direction are standard for the majority of CNC vertical machining centers and manual mills. With a 0.5 inch shank diameter matching the cutter diameter, it seats directly in standard ER or straight-bore collet systems without an adapter.

Key Features

• 0.03 inch corner radius reduces stress concentration at milled edges and extends part fatigue life
• Micrograin solid carbide construction for superior hardness and edge retention
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• Right-hand spiral flutes with right-hand cutting direction for standard CNC spindle use
• Bright uncoated finish suitable for aluminum, brass, and general-purpose steel applications
• Spiral flute geometry promotes chip evacuation during slotting and profiling cuts

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC vertical machining centers and manual knee mills accepting a 0.5 inch shank end mill.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before loading or removing the tool. Seat the shank fully into the collet or holder to the recommended engagement depth before torquing the retention nut. Verify runout with a dial indicator after clamping and before initiating a cutting program.
