Eagle Cutting Tool DT-1228-I 12-28 Nf Hss Combo Tap Drill

Product Description

The EAGLE CUTTING TOOL DT-1228-I is a combination tap and drill tool designed to perform two operations in a single pass: drilling a pilot hole and cutting threads simultaneously. Made from high-speed steel (HSS), this tool is sized for the 12-28 NF (National Fine) thread specification, making it well suited for applications that require fine-thread fastening in metal workpieces. The combination design reduces setup time and eliminates the need to change tools between drilling and tapping steps. It is a practical choice for machinists, maintenance technicians, and trade professionals working in fabrication, mechanical assembly, or field repair applications.

This combination tap drill is used in applications where 12-28 NF threaded holes are needed in ferrous metals, aluminum, and similar machinable materials. It is commonly used in mechanical and electrical trades for panel work, equipment enclosures, and structural fastening where fine-thread engagement is required. The import designation indicates this is a cost-effective sourced version of the standard combination tap drill format, suitable for general-purpose professional use.

Installation Notes

This tool is typically used by machinists and mechanical technicians in shop or field environments. Secure the workpiece firmly before operation and use appropriate cutting fluid to extend tool life and improve thread quality. Operate at recommended HSS cutting speeds for the material being tapped. Inspect the tool for wear or damage before each use to avoid broken taps in the workpiece.
