KSTE Hex Shank Drill Bits, 6pcs Metric Thread M3 M10 Titanium Coated HSS and Tap Bits 1/4"

Dual-Function Efficiency---These Drill and Tap Bits combine drilling and threading in one operation, saving of your machining time. The spiral flute design clears chips automatically while creating perfect threads from M3 to M10 in aluminum, copper, and plastics - no tool changes needed Professional-Grade---Made from nitrided high-speed steel with titanium coating, our Thread Tap Tools offer superior hardness (HRC62-65) and rust resistance. They last longer than standard taps while maintaining sharp cutting edges through heavy use in lathes and CNC machines Precision Machine Tapping---The 1/4" hex shank ensures secure machine mounting for vibration-free operation. Unlike hand taps, these Screw Taps Tool Set must be kept vertical during operation and the speed must be adjusted to the slowest, otherwise the tap will break (the thickness of the workpiece is less than 5mm) Complete Metric Threading Kit---This 6-piece Tap Drill Bit Set covers all common metric sizes (M3-M10) with matching pitches. The included M3(0.5mm) to M10(1.5mm) taps handle everything from fine electronics to heavy-duty fasteners - the only threading kit you'll need Optimized Chip Evacuation---Advanced spiral flute geometry in these Drill Tap Combination bits prevents clogging and breakage. The design pushes chips forward during operation, enabling continuous threading in deep holes without backing out
