Accupro 12181262 Corner Radius End Mill 1/8 in 2 Flute

Product Description

The ACCUPRO 12181262 is a solid carbide corner radius end mill designed for precision milling in ferrous and non-ferrous materials. It features a 1/8 inch mill diameter, a 0.015 inch corner radius, and a TiCN (titanium carbonitride) coating that increases surface hardness and extends tool life in abrasive cutting conditions. With a 40-degree helix angle and two right-hand spiral flutes, this end mill promotes efficient chip evacuation and smooth cutting action. The micrograin carbide substrate supports tight tolerances and consistent edge geometry across production runs. Machinists and CNC operators in job shops, tool rooms, and production machining environments are the primary users of this tool.

This end mill is suited for slotting, profiling, and contouring operations on machining centers and CNC mills where a small-diameter, corner-radius tool is required. The 0.015 inch radius protects the cutting edge from chipping at the corner while producing a controlled radius on workpiece edges and pockets. The centercutting design allows plunge entry directly into the workpiece. It is commonly used in precision aerospace, mold and die, and general metalworking applications where tight tolerances and fine surface finishes are required.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance in demanding cuts
• TiCN coating increases surface hardness and reduces tool wear in abrasive materials
• 0.015 inch corner radius reduces edge chipping and produces controlled radii on part features
• 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Centercutting geometry allows direct plunge milling without a pre-drilled entry point
• Right-hand cutting and flute direction compatible with standard CNC spindle rotation

Compatibility

Designed as an OEM-style solid carbide corner radius end mill for use in standard 1/8 inch collets and tool holders on CNC machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the 1/8 inch shank fully and evenly in a clean, undamaged collet to maintain runout tolerances. Verify tool projection and cutting parameters against the machine and material specifications before initiating a cut.
