Eagle Cutting Tool HT-18750-8-T-I Hss Hand Taper Tap

Product Description

The EAGLE CUTTING TOOL HT-18750-8-T-I is a high-speed steel (HSS) hand taper tap sized at 1-7/8 inch diameter with 8 threads per inch (TPI). Taper taps feature a gradual thread lead that allows progressive cutting engagement, making thread starting easier in through holes and blind holes with sufficient depth. This tap is designed for manual hand tapping operations using a tap wrench or comparable hand tool. At 4.2 pounds, it is a substantial tool suited for large-diameter threading work in metal fabrication, maintenance, and repair environments. HSS construction provides good wear resistance across a range of workpiece materials.

This tap is used in applications requiring large-diameter unified coarse thread profiles, specifically 1-7/8 inch-8 UNC. Typical use cases include threading large fastener holes in structural steel components, heavy equipment repair, industrial machinery maintenance, and fabrication shops. The taper lead style is appropriate when threading through holes or when starting a thread before following with a plug or bottoming tap. It is intended for manual operation by machinists, millwrights, pipefitters, and maintenance mechanics working on large threaded connections.

Key Features

• 1-7/8 inch diameter, 8 TPI unified coarse thread form
• High-speed steel (HSS) construction for durability across common workpiece materials
• Taper lead design for progressive thread engagement and easier starting
• Suited for manual hand tapping with a tap wrench
• Import grade offering a cost-effective option for general maintenance and repair use

Compatibility

Designed for hand tapping 1-7/8 inch-8 UNC threads in through holes or deep blind holes where taper lead engagement is appropriate.

Installation Notes

This tap is intended for use by machinists, millwrights, or qualified maintenance mechanics. Ensure the workpiece is securely fixtured before beginning hand tapping. Apply appropriate cutting fluid for the workpiece material to reduce friction and extend tap life. Never force the tap; back off periodically to break chips and prevent tap breakage, especially in deeper holes.
