Eagle Cutting Tool HT-1224-T-D 12-24 Hss Hand Taper Tap

Product Description

The EAGLE CUTTING TOOL HT-1224-T-D is a 12-24 thread high-speed steel (HSS) hand taper tap manufactured in the USA. Taper taps are ground with a gradual lead — typically 7 to 10 threads of taper — that distributes cutting load across multiple teeth, making thread starting easier in both through-holes and blind holes. This tap is sized for the 12-24 unified coarse thread form, a common fastener standard found throughout HVAC equipment, electrical enclosures, and light-duty mechanical assemblies. It is installed by hand with a tap wrench and is appropriate for threading ferrous and non-ferrous materials.

The HT-1224-T-D is suited for maintenance, repair, and fabrication work where 12-24 threaded holes are required or need to be re-chased. Typical applications include tapping sheet metal brackets, control panel enclosures, and small-diameter bosses in HVAC and electrical equipment. Its taper geometry makes it the preferred starting tap when beginning a new thread in a drilled hole, particularly when working by hand in the field or on a bench.

Key Features

• 12-24 unified coarse thread form for broad fastener compatibility
• High-speed steel (HSS) construction provides hardness and heat resistance during cutting
• Taper grind distributes cutting load for easier thread starting
• Manufactured in the USA
• Minimum order quantity of 1 — available as a single unit

Compatibility

Designed for hand tapping 12-24 unified coarse threaded holes in ferrous and non-ferrous materials; compatible with standard tap wrenches accepting the appropriate square drive shank.

Installation Notes

A licensed machinist, HVAC technician, or electrician performing field fabrication or repair work typically installs this tap using a hand tap wrench. Before tapping, drill the correct tap drill size for 12-24 thread engagement and deburr the hole entry. Apply cutting fluid appropriate to the workpiece material to extend tap life and reduce the risk of breakage. Never force a tap — back off a quarter turn periodically to break the chip and clear the flutes.
