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

Product Description

The EAGLE CUTTING TOOL HT-8750-14-P-I is a 7/8-14 high-speed steel (HSS) hand plug tap designed for cutting internal threads in metal workpieces. The plug chamfer — typically 3 to 5 threads of lead — makes it the standard choice for through-hole tapping and for starting threads in blind holes where a bottoming tap will finish the job. At 0.31 pounds, it is a lightweight, hand-driven tool suited for bench work and field repair across machining, mechanical, and maintenance trades.

This tap is used wherever a 7/8-14 UNF (Unified Fine) internal thread is required. Common applications include threading steel, cast iron, aluminum, and other machinable metals in repair shops, manufacturing floors, and field service environments. Machinists, millwrights, and maintenance mechanics reach for plug taps as the go-to starting tap for most general threading operations. The 14 threads-per-inch pitch is standard for fine-thread fastener applications in automotive, hydraulic, and mechanical assembly work.

Key Features

• 7/8-14 UNF thread form for fine-pitch internal threading
• High-speed steel (HSS) construction for durability across a range of workpiece materials
• Plug chamfer lead for versatile use in both through-holes and blind-hole starting applications
• Lightweight at 0.31 pounds for comfortable hand-tap use
• Minimum order quantity of 1 — available as a single-piece purchase

Compatibility

Designed as a standard hand plug tap for any application requiring a 7/8-14 UNF internal thread in machinable metal workpieces.

Installation Notes

Hand plug taps are installed using a tap wrench; secure the workpiece in a vise before beginning. Always use appropriate cutting fluid for the workpiece material to extend tap life and reduce the risk of breakage. Back the tap off periodically to break chips, especially in blind holes. Follow shop safety practices and wear eye protection when tapping by hand.
