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

Product Description

The EAGLE CUTTING TOOL HT-1224-T-I is a 12-24 UNC high-speed steel hand taper tap used to cut internal threads in metal, plastic, and composite materials. The taper lead — typically 8 to 10 threads of gradual thread engagement — makes thread starting easier and distributes cutting forces across multiple teeth, reducing the chance of tap breakage. At 0.02 pounds, it is a lightweight hand tool suited for bench work and field repairs. Machinists, millwrights, pipefitters, plumbers, and HVAC technicians reach for this size when threading small fastener holes in equipment, brackets, and panels.

The 12-24 thread designation means a No. 12 major diameter with 24 threads per inch, a common size in light-duty fastening applications across HVAC equipment, electrical enclosures, and plumbing fixtures. This tap is intended for hand tapping operations using a standard tap wrench and cutting fluid. It is appropriate for through-holes and can be followed by a plug or bottoming tap when blind holes require threads closer to the bottom.

Key Features

• 12-24 UNC thread form for a widely used light-duty fastener size
• High-speed steel construction resists heat generated during cutting
• Taper lead eases thread starting and reduces tap breakage risk
• Lightweight at 0.02 pounds for easy single-hand control
• Compatible with standard tap wrenches — no specialty tooling required

Compatibility

Designed as a standard hand taper tap for use in any application requiring 12-24 UNC internal threads in metal, plastic, or composite workpieces.

Installation Notes

Always secure the workpiece before tapping and use an appropriate cutting fluid to extend tap life and improve thread finish. Apply steady, even downward pressure while rotating the tap wrench, backing off a quarter turn periodically to break chips and prevent binding. Inspect the tap for wear or chipping before each use — a damaged tap can seize in the hole and break. This is a hand tapping operation; do not drive this tap with a power tool unless it is specifically rated for machine use.
