Description

The 1/4 UNC spiral flute tap and drill set is perfect for smaller-diameter threading applications commonly encountered in light fabrication, instrumentation work and general engineering. Producing a 5.1mm thread diameter with 17mm threading length, this compact combination tool handles quarter-inch UNC threads efficiently in a single operation, making it an essential addition to any toolkit for both trade professionals and home workshop enthusiasts. The steam-tempered high-speed steel construction provides excellent wear resistance whilst maintaining sharp cutting edges. The 6.3mm connection diameter suits standard power drill chucks, and the two-flute spiral configuration ensures reliable chip evacuation even in deeper holes. This tool eliminates the traditional workflow of switching between drill bits and taps, saving valuable time on repetitive threading tasks.
