Eagle Cutting Tool HT-8750-14-P-D 7/8-14 Hss Hand Plug Tap

Product Description

The EAGLE CUTTING TOOL HT-8750-14-P-D is a 7/8-14 high-speed steel (HSS) hand plug tap manufactured in the USA. Plug taps feature a chamfer of approximately 3-5 threads, making them suited for starting threads in through holes or continuing threads in blind holes after a taper tap has been used. This tool is ground from HSS for durability and edge retention under the demands of threading operations in a machine shop or field repair environment. Machinists, pipefitters, and maintenance technicians use plug taps as a standard part of hand threading workflows.

This tap is sized at 7/8 inch diameter with 14 threads per inch (7/8-14 UNF), placing it in the unified fine thread series. Fine-thread taps are commonly used where greater thread engagement strength or finer adjustment is needed in ferrous and non-ferrous metals. Typical applications include repair threading in automotive, industrial equipment, and mechanical assembly work where a fine-pitch thread form is specified.

Key Features

• 7/8-14 UNF thread form for fine-pitch threading applications
• High-speed steel (HSS) construction for wear resistance and long cutting life
• Plug chamfer profile suitable for through holes and continuation threading in blind holes
• Designed for hand tapping operations with a standard tap wrench
• Made in the USA

Compatibility

Designed as an OEM-style replacement or standard hand plug tap for use wherever a 7/8-14 UNF thread form is required in hand threading applications.

Installation Notes

This tap is installed by machinists or maintenance technicians using a standard tap wrench. Secure the workpiece before beginning and apply cutting fluid appropriate for the material being threaded to prolong tap life and reduce the risk of breakage. Back the tap out periodically to clear chips, especially in blind hole applications. Never force a tap against resistance, as HSS tools are brittle and susceptible to breakage under lateral stress.
