Eagle Cutting Tool HT-7500-10-B-D 3/4-10 Hss Bottom Tap

Product Description

The EAGLE CUTTING TOOL HT-7500-10-B-D is a 3/4-10 UNC high-speed steel (HSS) hand bottom tap manufactured in the USA. This tool cuts full threads to the bottom of a blind hole, making it the correct choice when thread depth requirements leave no room for a plug or taper tap to finish the job. At 0.32 pounds, it is a lightweight, handheld tool suited for bench work and on-site threading tasks. Machinists, pipefitters, maintenance mechanics, and general tradespeople reach for bottom taps when threading holes in steel, iron, aluminum, and similar materials where clearance at the base of the bore is limited.

This tap is used wherever a 3/4-10 UNC thread must be cut to the full depth of a blind hole. Common applications include fabricating threaded mounting points in structural steel, threading replacement holes in machinery housings, and field repair work on equipment fastener bores. The 3/4-10 thread designation indicates a 3/4-inch nominal diameter with 10 threads per inch, conforming to Unified National Coarse (UNC) standards widely used in industrial and mechanical assemblies across North American trades.

Key Features

• Bottom tap geometry allows threading to the full depth of blind holes
• High-speed steel (HSS) construction provides hardness and wear resistance for threading steel and cast iron
• 3/4-10 UNC thread form meets Unified National Coarse standards
• USA manufactured
• Lightweight at 0.32 pounds for easy handling during hand-tapping operations

Compatibility

Designed as an OEM-style replacement or direct-use hand tap for applications requiring a 3/4-10 UNC bottom tap in standard tap handles and tapping fixtures that accept the corresponding square shank drive.

Installation Notes

This tap is installed by hand using a suitable tap wrench or T-handle; secure the workpiece firmly in a vise before beginning. Apply cutting oil or tapping fluid to extend tool life and produce cleaner threads. Reverse the tap slightly every quarter to half turn to break chips and prevent binding. Inspect the tapped hole with a thread gauge after completion to verify thread form and depth before assembling fasteners.
