Eagle Cutting Tool DT-5000-13-I 1/2-13 Nc Hss Combo Tap Drill

Product Description

The EAGLE CUTTING TOOL DT-5000-13-I is a combination tap and drill designed for 1/2-13 NC (National Coarse) thread cutting in a single operation. High-speed steel (HSS) construction allows it to handle ferrous and non-ferrous materials without sacrificing edge retention under sustained use. The tool drills the pilot hole and cuts the thread in one pass, reducing setup time and the need to swap between separate bits and taps. It is used primarily by machinists, maintenance mechanics, and fabricators working in metal fabrication, industrial maintenance, and general manufacturing environments.

This combination tap drill is suited for tapping 1/2-13 NC threaded holes in steel, aluminum, cast iron, and similar workpiece materials. The single-tool operation is particularly effective in hand-drill and drill-press applications where production speed matters. It is well matched to maintenance and repair operations (MRO) as well as light manufacturing where 1/2-13 NC fastener holes are commonly required.

Key Features

• Combines drilling and thread cutting into a single operation for 1/2-13 NC threads
• High-speed steel (HSS) construction for durability across ferrous and non-ferrous materials
• National Coarse (NC) thread form — widely used in structural and general fastener applications
• Reduces tooling changeover time compared to using separate drill bits and taps
• Minimum order quantity of 1 unit — available for single-unit purchase

Compatibility

Designed as a replacement or standard-stocking combination tap drill for any application requiring 1/2-13 NC threaded holes. Fits standard drill chucks capable of accepting the tool shank diameter.

Installation Notes

Installation is performed by machinists or qualified maintenance mechanics using a drill press, mill, or hand drill with adequate torque control. Secure the workpiece firmly before drilling to prevent movement during thread cutting. Apply appropriate cutting fluid to extend tool life and improve thread quality, especially in steel. Follow applicable shop safety practices including eye protection and secure chuck engagement before operation.
