Accupro 12181259 Corner Radius End Mill 1/8 in 2 Flute

Product Description

The ACCUPRO 12181259 is a solid carbide corner radius end mill designed for precision milling operations in metal and composite materials. With a 1/8 inch diameter and a 0.045 inch corner radius, this tool produces smooth, radiused edges that reduce stress concentration and improve part surface finish. The 2-flute, right-hand spiral design with centercutting capability allows for both plunging and peripheral cutting. At 1-1/2 inches overall length with a 1/2 inch length of cut, it is suited for tight-tolerance work in die-and-mold, toolroom, and general machining applications. Machinists and tool-and-die professionals are the typical users.

This end mill fits small-format milling applications where tight corner radii and fine finishes are required. The bright/uncoated finish and micrograin carbide substrate make it well suited for non-ferrous metals, aluminum, brass, and soft steels where coating buildup is a concern or where the operator prefers an uncoated tool for specific material compatibility. Single-end configuration makes it a standard drop-in for CNC machining centers and manual mills using 1/8 inch collets or chucks.

Key Features

• Solid micrograin carbide construction for rigidity and extended tool life in precision cuts
• 0.045 inch corner radius reduces edge chipping and stress concentration on workpiece corners
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand flute direction and right-hand cutting for standard spindle operation
• Bright/uncoated finish suitable for non-ferrous and soft ferrous materials
• Spiral flute type promotes efficient chip evacuation during cut

Compatibility

Designed as an OEM-style replacement or standard cutting tool for CNC machining centers and manual mills equipped with 1/8 inch collets, end mill holders, or precision chucks accepting a 1/8 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or tool-and-die technicians. Power down and lock out the spindle before changing tooling. Verify collet size matches the 1/8 inch shank diameter and confirm runout with a dial indicator before production cuts. Do not exceed the rated length of cut; extended overhangs beyond the specified reach can cause deflection and premature tool failure.
