Emuge CU519400.5013 Spiral Flute Tap 1/2-13 Unc Cobalt

Product Description

The EMUGE CU519400.5013 is a spiral flute tap designed for cutting internal threads in a range of metals commonly encountered in precision machining and fabrication. Built from cobalt high-speed steel with a TICN (titanium carbonitride) coating, this tap handles demanding materials while maintaining edge integrity over extended use. It carries a 1/2-13 UNC thread form, a 2B class of fit, and a 45-degree helix angle that helps evacuate chips efficiently from blind holes. The bottoming chamfer configuration allows threading close to the bottom of a hole. Licensed machinists and tool and die professionals are the primary installers and users of this tool.

This tap is suited for threading aluminum alloy, copper, copper alloy, stainless steel, and steel workpieces in both production shop and job-shop environments. The fast flute style and 45-degree helix angle make it particularly effective in CNC tapping operations where consistent chip flow is critical. It is part of the EMUGE Enorm series, a line engineered for high-performance tapping in demanding materials and tight-tolerance applications requiring a 2B class of fit.

Key Features

• Cobalt HSS construction for heat resistance and extended tool life in tough materials
• TICN coating reduces friction and improves wear resistance
• 45-degree helix angle promotes fast, efficient chip evacuation from blind holes
• Bottoming chamfer allows threading to the base of blind holes
• 2B class of fit for standard precision internal threading
• Right-hand thread and right-hand flute direction for conventional tapping setups

Compatibility

Designed for threading aluminum alloy, copper, copper alloy, stainless steel, and steel. Part of the EMUGE Enorm series. No coolant-through capability. Not an oversize tap.

Installation Notes

This tap is installed by machinists using CNC machining centers or manual tapping equipment. Ensure the workpiece is securely fixtured and the spindle is properly aligned before tapping to avoid tap breakage. Use an appropriate cutting fluid or lubricant matched to the workpiece material. Follow machine manufacturer guidelines for spindle speed and feed rate when programming CNC tapping cycles.
