2. Craft & Performance
All drill bits of the 5PC Serrated Twist Drill Bit Set adopt high-strength high-speed steel substrate with integral serrated spiral flute milling molding, and the surface is covered with wear-resistant titanium gold anti-corrosion coating. The special serrated tooth structure on the spiral groove of the 5PC Serrated Twist Drill Bit Set greatly accelerates chip removal during drilling, avoiding debris winding and bit jamming on wood, plastic and soft metal surfaces.
The sharp split point tip of the 5PC Serrated Twist Drill Bit Set realizes automatic centering at the drilling starting point, effectively preventing sliding and scratching workpiece surfaces without auxiliary positioning tools. The thickened drill body of the 5PC Serrated Twist Drill Bit Set resists bending and breaking under heavy pressure, maintaining stable rotation at high drill speeds. The uniform titanium coating of the 5PC Serrated Twist Drill Bit Set reduces friction heat during long-time continuous drilling, slowing down bit wear and extending service life. Whether drilling thin ceramic tiles, solid wood boards or aluminum alloy sheets, the 5PC Serrated Twist Drill Bit Set can deliver neat, burr-free round holes every time you operate the 5PC Serrated Twist Drill Bit Set.
