Eagle Cutting Tool HT-6250-11-T-D Hand Taper Tap 5/8-11 Hss

Product Description

The EAGLE CUTTING TOOL HT-6250-11-T-D is a 5/8-11 high-speed steel (HSS) hand taper tap designed for cutting internal threads in a wide range of materials. Built with 4 flutes and an H3 tolerance class, it produces consistent, clean threads suited for production and maintenance work. The taper lead gradually engages the workpiece, reducing starting torque and making it well suited for hand tapping operations. At 0.32 pounds, it is a compact, single-piece tool manufactured in the USA to standard inch-thread specifications.

This tap is used in general metalworking, manufacturing, and maintenance environments where 5/8-11 UNC internal threads are required. Typical applications include threading steel, cast iron, aluminum, and similar materials in structural, mechanical, and industrial assemblies. Machinists, tool-and-die workers, maintenance mechanics, and pipefitters will encounter this size regularly when working with standard fastener and bolt patterns. The 4-flute design provides good chip clearance and cutting stability in through-hole and open-application tapping scenarios.

Key Features

• 5/8-11 UNC thread size for common standard fastener applications
• High-speed steel (HSS) construction provides hardness and wear resistance across a range of materials
• H3 tolerance class ensures consistent thread fit within standard limits
• 4-flute geometry promotes chip clearance and stable cutting action
• Taper lead style eases thread entry and reduces starting torque during hand tapping
• USA manufactured to inch-thread standards

Compatibility

Designed as a standard 5/8-11 UNC hand taper tap suitable for use with matching tap wrenches and holders that accept the corresponding square shank drive.

Installation Notes

This tap is installed by machinists or maintenance mechanics using a tap wrench sized for the shank. Always secure the workpiece and use appropriate cutting fluid to extend tool life and improve thread quality. Apply steady, even pressure and back off periodically to break chips, particularly in blind-hole applications. Follow applicable shop safety practices and ensure the correct drill size is used for the 5/8-11 thread prior to tapping.
