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. Features and benefits: combined drilling and tapping reduces operation time significantly steam-tempered coating retains lubricant for smoother cutting compact size ideal for smaller-diameter threading work two-flute design provides efficient swarf removal direct power tool compatibility eliminates need for tap wrenches right-hand thread cutting for standard applications specifications: diameter: 1 4 unc type: sprial flute shank: cylindrical shank with square connection diameter
