Accupro 12179312 Corner Rounding End Mill 0.010 in Radius

Product Description

The ACCUPRO 12179312 is a double-end, solid carbide corner rounding end mill designed to produce precise, consistent edge radii on machined workpieces. It features a 0.010-inch radius, a 1/8-inch mill diameter, and a 1/8-inch shank diameter, making it suited for fine detail work on harder materials. The TiN (titanium nitride) coating improves surface hardness and wear resistance, extending tool life in production environments. With 2 right-hand flutes and right-hand cutting direction, it delivers efficient chip evacuation in typical milling operations. This tool is installed and operated by machinists and CNC tooling technicians.

This end mill is used in machining centers and manual mills for generating small corner radii on metal components where a sharp edge must be broken or a uniform radius profile is required. The double-end configuration provides two usable cutting ends, reducing tooling cost per edge. It is commonly applied in die and mold work, precision part finishing, and general metalworking where small-radius edge profiling is specified on engineering drawings.

Key Features

• 0.010-inch corner radius for fine edge-breaking and small-profile rounding
• Solid carbide construction for rigidity and wear resistance in hard materials
• TiN coating increases surface hardness and extends tool life
• Double-end design provides two cutting ends per tool
• Right-hand cut and right-hand flute direction for standard milling spindle compatibility
• 1/8-inch shank fits standard collets and toolholders in that size range

Compatibility

Designed as an OEM-style corner rounding end mill compatible with standard 1/8-inch collets and toolholders used in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a qualified machinist or CNC technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank firmly in a properly sized collet or toolholder to the torque specified by the toolholder manufacturer. Inspect the cutting edges for chipping before each use, as carbide tools are brittle and can fracture if subjected to excessive side load or interrupted cuts beyond their designed parameters.
