Eagle Cutting Tool HT-1228-P-D 12-28 Hss Hand Plug Tap

Product Description

The EAGLE CUTTING TOOL HT-1228-P-D is a 12-28 high-speed steel hand plug tap manufactured in the USA. It is designed to cut internal threads in metallic and non-metallic workpieces by hand or with standard tapping equipment. The plug chamfer style features a moderate lead-in of several threads, making it suitable for through-holes and most general-purpose tapping applications. Machinists, maintenance technicians, and fabricators reach for this tap when threading holes to a 12-28 unified fine thread specification.

This tap is used in general metalworking, maintenance and repair operations, and light fabrication environments. The 12-28 thread size is common in instrument panels, electronic enclosures, and light mechanical assemblies where a fine thread pitch is required for secure fastening. It is appropriate for use in steel, aluminum, brass, and similar materials under normal hand tapping conditions.

Key Features

• 12-28 unified fine thread form for precision internal thread cutting
• Plug chamfer style provides a moderate lead-in suited to through-holes and most general tapping jobs
• High-speed steel construction offers durability and resistance to heat generated during cutting
• USA manufactured for consistent dimensional accuracy and thread quality
• Lightweight at 0.08 pounds, easy to handle in confined workspaces

Compatibility

Designed as an OEM-style replacement or direct-use hand plug tap for applications requiring a 12-28 unified fine internal thread.

Installation Notes

This tap is installed by machinists or maintenance technicians using a standard tap wrench or tapping handle. Before tapping, ensure the workpiece is securely clamped and the pilot hole is drilled to the correct tap drill size for a 12-28 thread. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Back the tap off periodically to break chips and prevent binding or breakage.
