Eagle Cutting Tool HT-6250-11-B-I 5/8-11 Hss Bottom Tap

Product Description

The EAGLE CUTTING TOOL HT-6250-11-B-I is a 5/8-11 high-speed steel (HSS) hand bottom tap designed for threading operations that require cutting threads as close to the bottom of a blind hole as possible. Bottom taps carry minimal taper on the lead threads, allowing full thread engagement nearly to the base of the hole. This tap is driven by hand using a tap wrench and is suited for use by machinists, pipefitters, maintenance technicians, and general trade professionals working in metal fabrication or repair applications where precise internal threading is required.

The HT-6250-11-B-I is intended for hand tapping 5/8-11 UNC (Unified National Coarse) threads in ferrous and non-ferrous metals. It is a common choice in maintenance, repair, and operations (MRO) environments where blind holes must be threaded to full depth. Typical applications include threading bolt holes in structural steel, machinery components, and fabricated assemblies. The import designation reflects the country of origin and is standard for this grade of tooling.

Key Features

• 5/8-11 UNC thread form for coarse-pitch internal threading
• Bottom tap geometry allows threading to near the base of blind holes
• High-speed steel (HSS) construction provides hardness and wear resistance for threading steel and other metals
• Hand-drive design compatible with standard tap wrenches
• Lightweight at 0.31 pounds for easy handling

Compatibility

Designed as an OEM-style replacement or standard hand tap for use in any application requiring 5/8-11 UNC internal threads in blind or through holes.

Installation Notes

This tap is intended for hand operation using a properly sized tap wrench. Always secure the workpiece before tapping and use cutting fluid appropriate for the material being threaded to reduce heat and extend tool life. Apply steady, even torque and back off periodically to break chips and prevent tap breakage. Follow applicable shop safety practices and OSHA general machine shop guidelines when operating cutting tools.
