Import BDNA-20675 Tap Set 10-32 Unf Hss Gold Oxide 3 Pc

Product Description

The IMPORT BDNA-20675 is a three-piece tap set designed for cutting 10-32 UNF threads in metal workpieces. The set includes bottoming, plug, and taper chamfer taps, allowing machinists and trade professionals to start, advance, and finish a threaded hole in a single workflow. Each tap features four flutes for efficient chip evacuation and is ground from high-speed steel (HSS) for durability across a range of ferrous and non-ferrous materials. A gold oxide finish provides light lubricity and corrosion resistance during use. Overall length of each tap is 2.375 inches. Thread limit is H3, suitable for general-purpose tapping tolerances.

This tap set is suited for maintenance, repair, and fabrication work requiring 10-32 UNF threaded fastener holes. The 10-32 thread is common in electrical enclosures, HVAC equipment, small assemblies, and light mechanical fabrication. The three-chamfer combination makes the set appropriate for both through-holes and blind holes. It is typically used by machinists, electricians, HVAC technicians, and general maintenance mechanics working with small fastener sizes in sheet metal or solid stock.

Compatibility

Designed for cutting 10-32 UNF threads in through-holes and blind holes in ferrous and non-ferrous materials where fine-thread tapping is required.

Installation Notes

Tapping operations should be performed by a qualified machinist or tradesperson using appropriate tapping fluid or cutting oil to extend tool life and improve thread quality. Secure the workpiece firmly before tapping to prevent movement. Follow applicable shop safety practices including eye protection and secure workholding. Inspect tap condition before each use and discard any tap showing chipped flutes or measurable wear.
