Eagle Cutting Tool HT-10000-12-P-D Hss Hand Plug Tap

Product Description

The EAGLE CUTTING TOOL HT-10000-12-P-D is a high-speed steel (HSS) hand plug tap ground to cut 1 inch diameter threads at 12 threads per inch (TPI). Plug taps feature a tapered lead of 3 to 5 threads, allowing them to start easily in through-holes or sufficiently deep blind holes while producing clean, accurate machine-screw or bolt threads. This tap is manufactured in the USA and is suited for use in hand tapping operations across a range of materials including mild steel, aluminum, brass, and similar machinable metals. Machinists, pipefitters, and maintenance technicians reach for plug taps as the general-purpose choice when threading new holes or chasing damaged threads.

This tap is designed for 1 inch 12 TPI unified coarse-adjacent thread applications where a plug chamfer starting geometry is required. It is appropriate for manual hand tapping with a tap wrench in production, maintenance, and repair operations across industrial, mechanical, and trade settings. Typical applications include threading bolt holes in equipment housings, fixtures, structural components, and fabricated assemblies where a 1 inch fastener will be used.

Key Features

• High-speed steel construction for durability and heat resistance during cutting
• Plug chamfer (3 to 5 thread lead) for easy starting in through-holes and deep blind holes
• 1 inch diameter, 12 TPI thread specification
• USA manufactured for consistent dimensional accuracy and thread quality
• Compatible with standard tap wrenches and hand tapping operations

Compatibility

Designed as an OEM-style hand tap for use in standard 1 inch 12 TPI tapping applications with any compatible tap wrench or holder accepting the appropriate square-drive shank size.

Installation Notes

This tap is intended for use by machinists, maintenance technicians, and trade professionals performing hand tapping operations. Always drill the correct tap drill size before tapping to avoid tool breakage and ensure proper thread engagement. Use cutting fluid appropriate for the workpiece material to extend tap life and improve thread finish. Back the tap off periodically during hand tapping to break chips and reduce the risk of tap breakage in blind holes.
