Eagle Cutting Tool HT-8750-14-B-I Hss Hand Bottom Tap 7/8

Product Description

The EAGLE CUTTING TOOL HT-8750-14-B-I is a 7/8-14 UNF hand bottom tap ground from high-speed steel (HSS). Bottom taps are designed to cut threads to the very end of a blind hole, making them the right choice when thread depth is critical and a plug or taper tap cannot complete the job. This tap is turned by hand using a standard tap wrench and is suited for threading operations in steel, aluminum, cast iron, and similar materials. It is an import-grade tool offering reliable performance for general shop and field use.

This tap is used in machining, fabrication, and maintenance applications wherever 7/8-14 UNF internal threads are required in blind holes. Machinists, tool-and-die workers, maintenance mechanics, and trade professionals reaching the bottom of a threaded bore will reach for a bottom tap to finish the thread form after starting with a taper or plug tap. It fits standard tap wrench collets sized for 7/8-inch taps.

Key Features

• 7/8-14 UNF thread form cuts fine-pitch internal threads with controlled tolerance
• Bottom tap geometry allows threading to the floor of blind holes
• HSS construction provides good wear resistance and toughness across common work materials
• Hand tap design compatible with standard tap wrenches and T-handles
• Import-grade tool suited for general production and maintenance use

Compatibility

Designed as an OEM-style replacement or direct-use hand tap for any application requiring 7/8-14 UNF internal threads in blind or through holes.

Installation Notes

Secure the workpiece before tapping and use a proper tap wrench to maintain straight alignment with the drilled hole. Apply cutting fluid or tapping compound appropriate for the work material to extend tool life and produce cleaner threads. Back the tap off a half turn for every full turn of advance to break chips and prevent binding. Discard the tap if it shows signs of chipping, cracking, or excessive wear to avoid thread damage or tool breakage in the bore.
