Import BDNA-20670 Tap Set 6-32 Unc 3 Flute Hss

Product Description

The IMPORT BDNA-20670 is a 3-piece tap set designed for cutting 6-32 UNC internal threads in metal workpieces. The set includes three tap styles — bottoming, plug, and taper — allowing machinists and technicians to start, advance, and finish threads in a single workflow without switching between separate toolsets. Taps are manufactured from High Speed Steel (HSS) with a Gold Oxide finish that provides lubricity and mild corrosion resistance during cutting operations. Overall length is 2 inches. The H3 thread limit designation indicates a standard tolerance class suited to general-purpose fastener thread production.

This tap set is used across metalworking, maintenance, and repair applications where 6-32 UNC threaded holes are required. The 6-32 thread size is common in light-duty machine assemblies, electrical enclosures, HVAC controls, and panel hardware. The three-chamfer configuration — taper for starting, plug for through-holes, and bottoming for blind holes — makes this set appropriate for both production and field repair scenarios. Machinists, maintenance technicians, and trade professionals working with thin-gauge steel, aluminum, and similar materials will find this a practical everyday toolset.

Key Features

• Three-piece set includes bottoming, plug, and taper chamfer taps for complete thread-cutting workflow
• 6-32 UNC thread standard for light-duty machine and panel hardware applications
• High Speed Steel construction for durability across repeated cuts in ferrous and non-ferrous metals
• Gold Oxide finish reduces friction and provides mild surface protection during use
• H3 thread limit for standard general-purpose thread tolerance
• 3 flutes for efficient chip evacuation during tapping

Compatibility

Designed for cutting 6-32 UNC internal threads in standard tapping applications across light metals and similar materials. Compatible with any standard tap wrench or machine holder sized for the shank of a 6-32 tap.

Installation Notes

Use of cutting fluid or tapping lubricant is standard practice when threading ferrous metals to extend tap life and improve thread quality. Begin with the taper tap to start the thread, follow with the plug tap, and finish with the bottoming tap when threading blind holes. Secure the workpiece firmly before tapping to prevent movement. When used in machine tapping setups, verify spindle speed and feed rate are appropriate for the material being threaded.
