Eagle Cutting Tool DT-3125-24-I 5/16-24 Nf Hss Combo Tap Drill

Product Description

The EAGLE CUTTING TOOL DT-3125-24-I is a combination tap and drill tool ground from high-speed steel (HSS) for 5/16-24 NF (National Fine) threaded hole applications. This import-grade combo tool performs the drilling and tapping operation in a single pass, reducing setup time and tool changes on the job. It is suited for use in metalworking, maintenance, and repair applications where a clean, accurately threaded hole is required. The 5/16-24 NF thread specification makes it appropriate for fine-thread fastener installations in ferrous and non-ferrous materials.

This combination tap drill is used wherever a technician or machinist needs to drill and tap a 5/16-24 NF threaded hole without switching between separate drill and tap tools. Typical applications include mechanical assembly, equipment repair, and field service work on metal components. It is well suited for trade professionals and shop technicians working with fine-thread fasteners in steel, aluminum, and similar materials.
