Accupro 12181267 Corner Radius End Mill 1/8 in 2 Flute

Product Description

The ACCUPRO 12181267 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. With a 1/8 inch cutting diameter and a 0.01 inch corner radius, this tool produces consistent, lightly radiused edges that reduce stress concentrations in finished workpieces. The AlTiN coating provides high heat resistance and extended tool life in ferrous and hard materials. It features a single-end, centercutting design with a right-hand spiral flute pattern and 40-degree helix angle, making it suitable for plunge, slot, and profile milling. Machinists and tool-and-die professionals use this end mill in CNC machining centers and manual mills.

This end mill is suited for use in light-duty to medium-duty milling applications on steel, stainless steel, cast iron, and similar ferrous alloys. The micrograin carbide substrate supports high-speed cutting with tight dimensional tolerances. The 1/2 inch length of cut accommodates shallow-to-moderate depth passes, while the 1/8 inch shank diameter fits standard collet chucks on CNC machining centers and manual knee mills. It is a single-quantity tool commonly stocked by job shops, mold makers, and precision machine shops.

Key Features

• 0.01 inch corner radius reduces edge chipping and stress risers in finish passes
• AlTiN coating improves heat resistance and extends tool life in ferrous materials
• Solid micrograin carbide substrate supports tight tolerances and rigidity
• Centercutting design allows direct plunge entry into the workpiece
• 40-degree helix angle promotes efficient chip evacuation
• Right-hand flute direction and cutting direction for standard spindle rotation

Compatibility

Designed as an OEM-style replacement or standard tooling selection for 1/8 inch collet chucks and tool holders used on CNC machining centers and conventional milling machines requiring a 1/8 inch shank end mill.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The tool must be seated fully and evenly in a properly sized collet or end mill holder before tightening to prevent runout. Verify spindle speed and feed rate parameters against the tool manufacturer's recommendations for the specific workpiece material before cutting. Inspect the collet and holder for wear or contamination prior to installation to maintain shank diameter tolerance specifications.
