Accupro 12176815 Corner Radius End Mill 1/2 in 3 Flute Carbide

Product Description

The ACCUPRO 12176815 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining applications. With a 1/2 inch cutting diameter and a 0.06 inch corner radius, this tool produces smooth, radiused edges while reducing stress concentrations at inside corners. The 3-flute geometry balances chip evacuation and surface finish, making it well-suited for finishing passes and light to moderate material removal. At 2-1/2 inches overall length with a 5/8 inch length of cut, the stub-length profile provides added rigidity during cutting. A bright, uncoated finish is standard on this tool.

This end mill is used in CNC machining centers and manual mills for cutting ferrous and non-ferrous metals, plastics, and composites. The right-hand cut and right-hand flute direction suit standard spindle configurations. The centercutting design allows for plunge operations, increasing its versatility in general shop use. Coarse pitch flute spacing helps clear chips efficiently in typical milling scenarios. This tool is a standard choice for machinists performing contour milling, profiling, and slotting where a corner radius is required.

Key Features

• 0.06 inch corner radius reduces stress concentrations and improves edge quality
• Solid carbide construction provides rigidity and wear resistance over high-speed steel alternatives
• 3-flute, coarse pitch design balances chip clearance and surface finish
• Centercutting capability allows direct plunge entry into workpiece
• Bright/uncoated finish suitable for a broad range of general-purpose materials
• Stub length profile minimizes deflection for improved dimensional accuracy

Compatibility

Designed as a standard 1/2 inch shank corner radius end mill compatible with CNC machining centers and manual milling machines equipped with 1/2 inch collets or end mill holders using right-hand spindle rotation.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Ensure the spindle is fully powered down and locked out before changing tooling. Seat the 1/2 inch shank fully and evenly in the collet or tool holder and torque the retention mechanism per the holder manufacturer's specifications. Verify runout with a dial indicator before beginning production cuts.
