Eagle Cutting Tool HT-4375-14-T-D Hand Taper Tap 7/16-14

Product Description

The EAGLE CUTTING TOOL HT-4375-14-T-D is a 7/16-14 high-speed steel (HSS) hand taper tap designed for cutting internal threads in metal workpieces. The taper tap style features a gradual thread lead that distributes cutting forces across multiple flutes, making thread starting easier and more consistent. This tool is suited for use in hand tapping operations where a tap wrench or T-handle driver is used to thread through-holes or blind holes in steel, cast iron, aluminum, and similar materials. At 0.32 pounds, it is a lightweight, single-piece cutting tool built to standard UNC thread specifications.

This tap is used in maintenance, repair, and fabrication environments where 7/16-14 UNC threads need to be cut by hand. Typical applications include threading bolt holes in structural components, equipment frames, and machined parts. It is a standard tool in the inventory of machinists, pipefitters, millwrights, and mechanical contractors. The taper style is the preferred starting tap when threading new holes, as it allows the technician to align the tap squarely before full thread engagement begins.

Key Features

• 7/16-14 UNC thread form for standard unified coarse thread applications
• High-speed steel (HSS) construction provides wear resistance across a range of workpiece materials
• Taper tap geometry distributes cutting load for easier thread starting and straighter alignment
• Hand tap design compatible with standard tap wrenches and T-handle drivers
• Lightweight at 0.32 pounds for single-hand operation

Compatibility

Designed as an OEM-style replacement or standard-stock hand tap for use in any application requiring 7/16-14 UNC internal threads cut by hand tapping methods.

Installation Notes

Thread cutting should be performed by a qualified machinist or trade technician familiar with proper tapping procedures. Always use a suitable cutting fluid or tapping oil to reduce heat and extend tap life. Back the tap out periodically to clear chips, especially in blind holes, to prevent tap breakage. Inspect the tap for chipped or worn flutes before each use and replace if damage is present.
