For professionals and DIY enthusiasts working with metal, wood, or plastic, this 5-piece drill bit set from RUKO offers reliable performance and convenience. The bits feature a titanium nitride (TiN) coating that reduces friction and improves heat resistance, extending tool life. Each bit has a 135° split point for accurate starting without walking, and the 1/4" quick-lock hex shank allows fast bit changes in quick-lock chucks, standard drill chucks, and impact drivers.
