Eagle Cutting Tool HT-13750-6-P-I Hss Hand Plug Tap 1-3/8 6 Tpi

Product Description

The EAGLE CUTTING TOOL HT-13750-6-P-I is a high-speed steel (HSS) hand plug tap designed for cutting internal threads in a 1-3/8 inch diameter at 6 threads per inch (TPI). The plug chamfer style features a gradual lead-in of several threads, making it well suited for threading through holes as well as moderately deep blind holes. At 0.31 pounds, this is a solid, hand-use tap intended for machinists, pipefitters, maintenance technicians, and fabricators who need a reliable threading tool for large-diameter, coarse-pitch applications.

This tap is used in metalworking and industrial maintenance applications where large-diameter internal threads are required. Common scenarios include fabricating or repairing threaded connections in structural components, heavy equipment, and industrial machinery. The coarse 6 TPI pitch is typical for large fastener and structural threading work. This is an import-grade tool appropriate for general-purpose shop use where volume or cost constraints make domestic tooling impractical.

Key Features

• 1-3/8 inch diameter, 6 TPI coarse thread specification for large-diameter internal threading
• High-speed steel (HSS) construction provides hardness and wear resistance across a range of workpiece materials
• Plug chamfer lead-in suits both through-hole and moderately deep blind-hole applications
• Hand tap design for use with a tap wrench or tap handle
• Import-grade tooling offering cost-effective performance for general shop use

Compatibility

Designed as a general-purpose hand plug tap for use in standard 1-3/8 inch-6 UNC threaded applications in metalworking and industrial maintenance environments.

Installation Notes

This tap is installed by a machinist or skilled tradesperson using a properly sized tap wrench. The workpiece should be secured firmly before tapping begins, and appropriate cutting fluid should be applied to extend tool life and improve thread quality. Back the tap off periodically to break chips and prevent binding, particularly in deeper holes. Follow standard shop safety practices and wear eye protection during all tapping operations.
