Eagle Cutting Tool HT-10000-8-P-I 1-8 Hss Hand Plug Tap

Product Description

The EAGLE CUTTING TOOL HT-10000-8-P-I is a 1 inch - 8 TPI high-speed steel (HSS) hand plug tap designed for cutting internal threads in through holes and blind holes. The plug chamfer — typically 3 to 5 threads — makes it a versatile starting point for most hand-tapping operations, suitable for use after a taper tap or as a standalone tap in through-hole applications. At 0.63 pounds, it is a solid, manageable tool for bench work and field threading tasks. Machinists, pipefitters, and maintenance technicians use this tap when creating or restoring 1 inch coarse-thread (8 TPI) internal threads in metal workpieces.

This tap is suited for hand-tapping operations in ferrous and non-ferrous metals using a standard tap wrench or T-handle. The 1 inch - 8 UNC thread form is a heavy coarse-thread standard commonly found in structural fastening, pipe flanges, heavy machinery, and general industrial fabrication. It is appropriate for shop and field use where a durable HSS cutting tool is required for low- to moderate-volume threading work.

Key Features

• 1 inch - 8 TPI coarse thread form for heavy industrial fastening applications
• High-speed steel (HSS) construction provides hardness and wear resistance for threading metal
• Plug chamfer style suits both through-hole and blind-hole threading
• Designed for hand-tapping use with standard tap wrenches
• Lightweight at 0.63 pounds for easy handling at the bench or in the field

Compatibility

Designed as a standard hand plug tap for use in any application requiring 1 inch - 8 UNC internal threads. Compatible with standard tap wrenches sized for large-shank taps.

Installation Notes

This tool is installed by a machinist, maintenance technician, or pipefitter using a tap wrench. Secure the workpiece firmly before tapping and apply cutting fluid appropriate for the base material to extend tool life and improve thread quality. Start the tap straight and square to the hole to avoid cross-threading or tap breakage. Follow applicable shop safety practices when using cutting tools on powered or manual equipment.
