Eagle Cutting Tool HT-1224-B-D 12-24 Hss Bottom Tap

Product Description

The EAGLE CUTTING TOOL HT-1224-B-D is a 12-24 thread, high-speed steel (HSS) bottom tap manufactured in the USA. Bottom taps are designed to cut threads to the full depth of a blind hole, with a near-flat chamfer that allows threading right to the bottom of the bore. This tap is suited for threading steel, aluminum, and similar metals in production and repair applications. Machinists, maintenance technicians, and trade professionals use bottom taps as the final step in a three-tap sequence or whenever full-depth threading in a blind hole is required.

The HT-1224-B-D is sized for 12-24 unified coarse (UNC) thread, a fastener size common in HVAC equipment panels, electrical enclosures, and light structural assemblies. It is appropriate for use in both shop and field repair settings where hardware must be re-threaded or new threads must be cut into metal components. The USA-made construction reflects consistent dimensional tolerances that production and service environments require.

Key Features

• Bottom chamfer profile threads blind holes to near-full depth
• High-speed steel (HSS) construction provides durability across steel and aluminum workpieces
• 12-24 UNC thread size suits common fastener applications in HVAC, electrical, and mechanical assemblies
• USA manufactured for consistent dimensional accuracy
• Lightweight at 0.08 pounds, suitable for hand tap handle or machine use

Compatibility

Designed as a standard 12-24 UNC bottom tap for use wherever 12-24 unified coarse threads must be cut to the base of a blind hole in metal or compatible materials.

Installation Notes

Bottom taps are typically the final tap used after a taper and plug tap have established the thread in a blind hole. Always secure the workpiece and use appropriate cutting fluid to extend tap life and improve thread quality. Back the tap out periodically to clear chips when threading blind holes. Follow applicable shop safety practices and wear eye protection during all tapping operations.
