Accupro 12179318 Corner Rounding End Mill 3/16 in Carbide Tin

Product Description

The ACCUPRO 12179318 is a double-end corner rounding end mill designed to produce consistent, radius-edged profiles on ferrous and non-ferrous workpieces. Built from solid carbide with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction in production and job-shop environments. The cutting geometry features a 0.046 inch radius, a 0.1875 inch mill diameter, and a 0.095 inch tip diameter. With 2 right-hand flutes and right-hand cutting direction, the tool is suited for conventional CNC milling operations. The 2 inch overall length keeps the tool compact and rigid during edge-break and radius-forming passes.

This end mill is used in machining applications where a controlled corner radius is required on part edges, slots, or shoulders. It is typically run on CNC machining centers or manual mills by machinists and tool-and-die professionals working with steel, stainless, aluminum, and similar materials. The double-end configuration provides two usable cutting ends, extending the service life per tool and reducing per-part tooling cost in repeat production runs.

Key Features

• Solid carbide construction provides rigidity and wear resistance in demanding cuts
• TiN coating reduces friction and extends tool life compared to uncoated carbide
• Double-end design yields two cutting ends per tool for greater value per piece
• 0.046 inch corner radius generates consistent, repeatable edge profiles
• Right-hand flute and cut direction compatible with standard CNC spindle rotation
• 3/16 inch shank diameter fits standard collets and tool holders without adapters

Compatibility

Designed as a standard corner rounding end mill for use in CNC machining centers and manual milling machines equipped with a 3/16 inch collet or tool holder capable of accepting a 0.1875 inch shank.

Installation Notes

Installation should be performed by a qualified machinist. Secure the shank fully into a clean, properly sized collet or end mill holder and torque the drawbar or collet nut per the spindle manufacturer's specification. Inspect the cutting edges before use and discard any tool showing chipping or coating breakdown. Always verify spindle RPM and feed rate are appropriate for the workpiece material before beginning a cut.
