Eagle Cutting Tool HT-540-T-I 5-40 Hss Hand Taper Tap

Product Description

The EAGLE CUTTING TOOL HT-540-T-I is a 5-40 high-speed steel (HSS) hand taper tap designed for manually threading 5-40 UNC holes in metal workpieces. The taper tap features a gradual lead that distributes cutting forces across several flutes, making thread starting easier and more accurate in through-holes and blind holes with sufficient depth. At 0.31 pounds, it is a lightweight, hand-held tool suited for bench work and field use. Machinists, maintenance technicians, and trade professionals who require clean, accurate 5-40 threads in steel, aluminum, and similar materials will find this tap a reliable option for production and repair applications.

This tap is suited for hand tapping operations where a tap wrench or T-handle driver is used to drive the tool by hand. The 5-40 thread designation indicates a No. 5 screw diameter with 40 threads per inch, a thread size common in instrument assemblies, light mechanical fastening, and precision metalwork. It is appropriate for use in both shop and field environments where a power tapping setup is not available or practical.

Key Features

• 5-40 UNC thread form for compatibility with No. 5 screw fasteners at 40 threads per inch
• High-speed steel (HSS) construction for durability and resistance to heat during cutting
• Taper lead design distributes cutting load across multiple threads for easier starting
• Lightweight at 0.31 pounds for comfortable hand tapping use
• Minimum order quantity of 1, suitable for single-unit purchase

Compatibility

Designed as a hand taper tap for creating 5-40 UNC threads in metallic workpieces; intended for use with standard tap wrenches and T-handle drivers compatible with the appropriate shank size for this thread class.

Installation Notes

This tap is a cutting tool installed by machinists or maintenance technicians using a tap wrench or suitable hand driver. Always secure the workpiece firmly before tapping and apply a cutting fluid appropriate for the base material to extend tap life and improve thread quality. Back off the tap periodically to break chips and prevent binding, especially in blind holes. Inspect the tap for chipping or wear before each use, and do not force a worn or damaged tap.
