Eagle Cutting Tool HT-6250-18-P-D 5/8-18 Hss Hand Plug Tap

Product Description

The EAGLE CUTTING TOOL HT-6250-18-P-D is a 5/8-18 high-speed steel (HSS) hand plug tap manufactured in the USA. It is designed to cut internal threads by hand in metal workpieces where a 5/8-18 UNF thread form is required. The plug chamfer — typically 3 to 5 threads of taper — allows the tap to start easily in a drilled hole and is the most common choice for through-holes and general-purpose tapping work. Machinists, pipefitters, and maintenance technicians reach for this tap when creating or restoring fine-thread fastener holes in ferrous and non-ferrous materials.

This tap is suited for shop and field use wherever 5/8-18 UNF internal threads are needed. Common applications include threading holes in steel brackets, flanges, and machine components where a fine thread pitch is preferred for its stronger thread engagement and better resistance to vibration-induced loosening compared to coarse-pitch alternatives. It is used in both production shops and maintenance-repair-operations (MRO) environments.

Key Features

• 5/8-18 UNF thread form for fine-pitch internal threading
• High-speed steel (HSS) construction for durability across a range of metals
• Plug chamfer style for versatile through-hole and general-purpose use
• Hand tap design intended for use with a standard tap wrench
• USA manufactured

Compatibility

Designed as a general-purpose hand plug tap for use in any application requiring 5/8-18 UNF internal threads in ferrous and non-ferrous workpieces.

Installation Notes

This tap is installed by a machinist or maintenance technician using a standard tap wrench. Ensure the workpiece is secured before tapping, and use an appropriate cutting fluid to extend tool life and improve thread finish. Back off the tap periodically to break chips and prevent tap breakage. Follow applicable shop safety practices when handling cutting tools.
