Eagle Cutting Tool HT-5000-20-P-I 1/2-20 Hss Hand Plug Tap

Product Description

The EAGLE CUTTING TOOL HT-5000-20-P-I is a 1/2-20 high-speed steel (HSS) hand plug tap designed for cutting internal threads by hand. The plug chamfer — typically 3 to 5 threads of taper — makes it suitable for threading through-holes and most standard blind-hole applications where a starter tap is not required. At 0.31 pounds, it is a lightweight tool suited for bench work and field use. Machinists, pipefitters, maintenance technicians, and general tradespeople use plug taps when threading ferrous and non-ferrous materials to a 1/2-20 UNF specification.

This tap is intended for hand tapping operations using a standard tap wrench or T-handle. The 1/2-20 UNF thread designation indicates a 1/2-inch nominal diameter with 20 threads per inch — a fine-thread series commonly found in automotive, mechanical, and light structural fastening applications. It is appropriate for job-site repairs, shop fabrication, and maintenance work where threading new holes or chasing damaged threads to the 1/2-20 UNF standard is required.

Key Features

• 1/2-20 UNF thread form — fine-thread series for precise fastener engagement
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous materials
• Plug chamfer profile suitable for through-holes and standard blind-hole threading
• Lightweight at 0.31 pounds for easy handling during hand tapping operations
• Minimum order quantity of 1 — available as a single unit

Compatibility

Designed for hand tapping applications requiring a 1/2-20 UNF internal thread. Compatible with standard tap wrenches and T-handle drivers sized for 1/2-inch tap shanks.

Installation Notes

Use with a properly sized tap wrench to maintain alignment and control torque during hand tapping. Apply cutting fluid appropriate to the workpiece material to extend tap life and improve thread finish. Back the tap off periodically to break chips, especially in blind-hole applications. Inspect the tap for chipping or wear before each use — a damaged tap can seize in the workpiece.
