Ideal Size: Precise drilling for holes from 5 to 35 mm in diameter; one drill bit is suitable for multiple diameters. Premium Material: The titanium alloy coating is made of high-speed steel (HSS), ensuring exceptional durability and reducing friction and heat. Titanium alloy drill bits are particularly suitable for machining thin workpieces made of copper, aluminum, iron, wood, plastic, and other thin sheet materials. Easy Drilling: Markings and a double flute facilitate faster, smoother, and more accurate drilling. Laser Engraving: Dimensions are laser-engraved onto the metal, ensuring wear resistance even after repeated use.
