Accupro 12181896 Corner Radius End Mill 1/8 in 3 Flute Carbide

Product Description

The ACCUPRO 12181896 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. It features a 1/8 inch diameter with a 0.02 inch corner radius, a 3-flute spiral geometry, and a TiCN coating that extends tool life in ferrous and non-ferrous materials. With a 1/2 inch length of cut and 1-1/2 inch overall length, this single-end, centercutting tool handles both plunge and peripheral milling. Micrograin carbide construction provides rigidity and edge retention at elevated cutting speeds. Installed and run by machinists and CNC operators in production and job-shop settings.

This end mill is suited for finish milling, contouring, and profiling operations where a small corner radius is required to reduce stress concentrations at part features. The TiCN coating makes it appropriate for use on alloy steels, stainless steels, cast iron, and similar hard materials. Its compact 1/8 inch shank and diameter make it well matched to small-part work, die and mold detail passes, and tight-tolerance slot or pocket operations on CNC machining centers and manual mills.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• TiCN coating extends tool life in ferrous and abrasive materials
• 0.02 inch corner radius reduces stress concentrations at milled features
• 3-flute spiral geometry balances chip evacuation with surface finish quality
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Right-hand flute direction and right-hand cutting for standard CNC spindle use

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for CNC machining centers and manual mills accepting a 1/8 inch straight shank tool holder or collet.

Installation Notes

Installation is performed by a machinist or CNC operator using a compatible collet or end mill holder sized for a 1/8 inch shank. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before securing the tool. Confirm runout with a dial indicator before beginning a production run, as the shank diameter tolerance range of -0.0001 to -0.0004 inches requires a properly sized collet for accurate seating. Follow machine tool manufacturer guidelines for feed, speed, and depth-of-cut parameters appropriate to the workpiece material.
