Accupro 12179324 Corner Rounding End Mill 1/4 in Solid Carbide

Product Description

The ACCUPRO 12179324 is a double-end corner rounding end mill designed to produce consistent radius profiles on workpiece edges in machining operations. Built from solid carbide, it delivers the rigidity and wear resistance required for high-speed cutting in ferrous and non-ferrous materials. The 0.085-inch corner radius generates a smooth, repeatable fillet, while the titanium nitride (TiN) coating reduces friction and extends tool life. With a 1/4-inch mill diameter and 1/4-inch shank diameter, this tool mounts directly in standard collet chucks and end mill holders. The two-flute, right-hand cutting geometry suits general milling applications where chip clearance and surface finish are priorities.

This end mill is suited for use on CNC machining centers and manual mills in job shops, tool rooms, and production environments. It is commonly applied to edge-breaking, radius profiling, and deburring operations on aluminum, mild steel, stainless, and plastics. The double-end configuration provides two usable cutting ends, extending the value of each tool. Machinists and CNC operators working on precision components, fixtures, or mold work will find this tool applicable wherever a controlled 0.085-inch radius is specified on a print.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cutting applications
• Titanium nitride (TiN) coating reduces friction and improves tool longevity
• 0.085-inch corner radius for precise, repeatable edge profiling
• Double-end design provides two cutting ends per tool
• Right-hand cut and right-hand flute direction for standard spindle operation
• 1/4-inch shank diameter compatible with standard collet and end mill holder systems

Compatibility

Designed for use in CNC machining centers and manual milling machines accepting a 1/4-inch shank diameter end mill holder or collet chuck.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the 1/4-inch shank fully into the collet or end mill holder and torque the retention nut to the tool holder manufacturer's specification. Verify runout with a dial indicator before beginning production cuts to protect both the tool and the workpiece.
