Accupro 12179315 Corner Rounding End Mill 1/8 in 2 Flute

Product Description

The ACCUPRO 12179315 is a double-end corner rounding end mill designed to produce smooth, radiused edges on machined workpieces. Built from solid carbide and coated with TiN (Titanium Nitride) for improved hardness and heat resistance, this tool delivers consistent edge-breaking performance in production and maintenance machining environments. It features a 0.031 inch corner radius, a 0.125 inch (1/8 inch) mill diameter, and a 0.063 inch tip diameter. The right-hand cutting and right-hand flute direction suit conventional milling setups on CNC machining centers and manual mills alike. Machinists and toolroom professionals are the primary users.

This end mill is suited for edge rounding and corner blending operations on ferrous and non-ferrous metals in both job shop and production floor settings. The double-end configuration extends usable tool life by providing two cutting ends per shank. The 1/8 inch shank diameter makes it compatible with standard collet chucks and small-bore tool holders common on vertical mills, CNC routers, and precision machining centers handling tight-tolerance work. Applications include deburring, profile blending, and finish passes where a controlled radius is required.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• TiN coating improves surface hardness and reduces friction at the cutting edge
• Double-end design provides two usable cutting ends, extending tool life per unit
• 0.031 inch corner radius produces a precise, repeatable radiused edge
• Right-hand cut and right-hand helix for use in standard milling spindle configurations
• 2-flute geometry balances chip evacuation with edge strength on small-diameter tooling

Compatibility

Designed as a standard corner rounding end mill for use in collet chucks and tool holders accepting a 1/8 inch shank diameter on CNC machining centers, vertical knee mills, and similar milling equipment.

Installation Notes

Installation is performed by a machinist or toolroom technician. Secure the 1/8 inch shank in a properly sized collet or end mill holder and torque to the tool holder specification before operation. Inspect the cutting edges for chips or coating damage before each use. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and tool diameter.
