Eagle Cutting Tool HT-15000-8-T-I Hss Hand Taper Tap

Product Description

The EAGLE CUTTING TOOL HT-15000-8-T-I is a high-speed steel (HSS) hand taper tap sized 1-1/2 inch diameter with an 8 threads-per-inch (TPI) thread pitch. Taper taps feature a gradual lead-in chamfer across the first several threads, allowing the tool to start easily and cut progressively as it advances into the workpiece. This tap is intended for hand threading operations in metal fabrication, pipe fitting, and general mechanical work where large-diameter internal threads are required. At 1.8 pounds, the tool is sized for heavy-duty threading tasks typical in plumbing, structural, and industrial maintenance applications.

This tap is suited for cutting 1-1/2 inch-8 UNC internal threads in ferrous and non-ferrous materials. Typical applications include threading flanged connections, heavy structural fittings, large mechanical assemblies, and repair threading in equipment housings. The taper chamfer makes it well-suited for through-hole applications where starting a tap by hand is required. It is commonly used by plumbers, pipefitters, millwrights, and maintenance machinists working on large-diameter fastener and fitting installations.

Key Features

• HSS construction provides hardness and wear resistance for threading steel, cast iron, and similar materials
• 1-1/2 inch diameter with 8 TPI UNC thread form for heavy-duty internal threading
• Taper chamfer lead-in for easy thread starting in through-hole and blind-hole entry applications
• Designed for hand tapping operations using a tap wrench or appropriate handle
• Import-grade tooling suitable for production and general maintenance use

Compatibility

Designed as a standard hand taper tap for cutting 1-1/2 inch-8 UNC internal threads. Compatible with any standard tap wrench or handle sized to accept large-diameter taps.

Installation Notes

This tap is installed by a machinist, pipefitter, or maintenance technician using a tap wrench sized for large-diameter taps. Secure the workpiece firmly before beginning the threading operation, and use a cutting fluid appropriate for the material being tapped to reduce heat and extend tool life. Back the tap out periodically to clear chips and prevent binding. Always verify that the correct tap drill size has been used prior to tapping to avoid breakage.
