Eagle Cutting Tool HT-6250-18-T-I 5/8-18 Hss Taper Tap

Product Description

The EAGLE CUTTING TOOL HT-6250-18-T-I is a 5/8-18 high-speed steel (HSS) hand taper tap designed for cutting internal threads in metal workpieces. The taper tap features a gradual thread lead that distributes cutting force across multiple teeth, making it well-suited for starting threads in through-holes or blind holes. At 0.31 pounds, it is a lightweight, hand-driven tool used with a standard tap wrench or T-handle. Machinists, pipefitters, and maintenance technicians reach for this tap when threading ferrous and non-ferrous materials to a 5/8-18 UNF specification.

This tap is used in general metalworking, maintenance, and repair applications where a 5/8-18 unified fine thread is required. The taper profile makes it a first-choice tap when starting a thread from scratch in through-hole applications, particularly in steel, cast iron, aluminum, and similar materials. It is well-suited for job-shop, field service, and production environments where hand tapping is the preferred method.

Key Features

• 5/8-18 UNF thread specification for unified fine thread applications
• High-speed steel (HSS) construction provides hardness and wear resistance for threading metal
• Taper lead distributes cutting load gradually, reducing tap breakage risk when starting threads
• Hand-tap design compatible with standard tap wrenches and T-handle drivers
• Lightweight at 0.31 pounds for easy handling in field or shop use

Compatibility

Designed as a standard hand taper tap for use in any application requiring a 5/8-18 UNF internal thread; compatible with standard tap wrenches sized for this thread range.

Installation Notes

A licensed machinist or qualified maintenance technician should perform thread-cutting operations. Before tapping, ensure the workpiece is securely clamped and the pilot hole is drilled to the correct tap-drill diameter for a 5/8-18 thread. Apply cutting oil throughout the tapping process to extend tap life and improve thread quality. Back the tap off periodically to break chips and prevent binding, especially in deeper holes.
