Titan Usa TC66508 Corner Radius End Mill 1/8 in 3 Flute

Product Description

The TITAN USA TC66508 is a solid carbide corner radius end mill designed for precision material removal in non-ferrous metals including aluminum, brass, and bronze. The cutter measures 0.1250 inches in diameter with a 0.0100 inch corner radius and runs three right-hand spiral flutes at a 45-degree helix angle. A ZrN (zirconium nitride) PVD coating reduces friction and extends tool life in high-speed non-ferrous applications. The centercutting geometry allows both plunge and peripheral milling operations. This tool is installed and operated by machinists and CNC operators working with toolholders in standard machining centers or milling machines.

The TC66508 is suited for finish and roughing passes on non-ferrous workpiece materials such as aluminum, brass, and bronze. With a long-length configuration, a 0.7500 inch reach length, and a 0.7500 inch length of cut, it handles slots, pockets, and contours that require extended reach beyond standard-length tooling. The straight cylindrical shank at 0.1250 inches diameter seats directly into compatible toolholders. The coarse pitch and high helix style promote chip evacuation, making it effective in high-feed aluminum machining environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in non-ferrous cutting
• ZrN PVD coating reduces built-up edge and improves tool life on aluminum and brass
• 0.0100 inch corner radius protects cutting edges and improves surface finish at part corners
• 45-degree high helix angle promotes aggressive chip evacuation
• Centercutting design allows direct plunge entry into workpiece material
• Single-end, right-hand cut with coarse pitch for efficient roughing and finishing passes

Compatibility

Designed for use with standard toolholders accepting a 0.1250 inch straight cylindrical shank. Primary workpiece materials are non-ferrous metals including aluminum, brass, and bronze. UNSPSC code 27112803.

Installation Notes

This end mill is installed by machinists in CNC machining centers or manual milling machines using a compatible toolholder. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify shank engagement depth and runout with a dial indicator before cutting. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.
