Eagle Cutting Tool HT-3750-24-P-I 3/8-24 Hss Hand Plug Tap

Product Description

The EAGLE CUTTING TOOL HT-3750-24-P-I is a 3/8-24 high-speed steel (HSS) hand plug tap designed for cutting internal threads in metal workpieces. The plug chamfer — typically 3 to 5 threads of taper — makes it the most common general-purpose tap for threading through holes and most blind-hole applications. At 0.31 pounds, it is a lightweight, hand-use tool suited for bench work and field repair. Machinists, pipefitters, and maintenance technicians reach for this tap when restoring or creating 3/8-24 UNF threads in steel, aluminum, and similar materials.

This tap is used in light industrial, maintenance, and repair settings where 3/8-24 unified fine thread profiles are required. The fine-thread pitch makes it common in automotive, hydraulic fitting, and precision mechanical assemblies where a finer thread engagement is needed over the coarser UNC equivalent. It is suitable for hand tapping with a standard tap wrench and cutting fluid, and fits into general shop, field service, and toolroom workflows.

Key Features

• 3/8-24 UNF thread form for fine-pitch internal threading applications
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous workpieces
• Plug chamfer style — approximately 3 to 5 thread lead — suitable for through holes and most blind holes
• Hand tap design for use with a standard tap wrench or T-handle
• Lightweight at 0.31 pounds for easy one-hand bench or field use

Compatibility

Designed as a standard hand plug tap for use in any application requiring 3/8-24 UNF internal threads in metal or compatible materials.

Installation Notes

This tap is installed by hand using a tap wrench — power driving is not recommended for hand taps, as it risks breakage. Secure the workpiece before threading, and use an appropriate cutting fluid to extend tap life and improve thread finish. Back the tap off periodically to break chips and prevent binding. Follow applicable shop safety practices and ensure the correct tap drill size is used before starting.
