About this item

• 【50-in-1 Ultimate Set: Steps, Countersinks & Punch】This professional kit includes 5 step drill bits, 5 countersink bits, and 1 center punch, covering over 50 sizes from 1/8” to 1-3/8”. It’s the complete step drill bit set for metal, wood, and plastic
• 【4241 HSS with Titanium Coating】Each bit is crafted from durable high-speed steel and enhanced with a titanium nitride coating. This combination provides superior heat and abrasion resistance, ensuring lasting sharpness and cleaner cuts through a wide range of materials
• Precision Design】The included 5-piece countersink bit set is designed for creating 90° seats for screws in wood and soft metal. Meanwhile, the step drills feature a 118° split point tip and double-flute design, which increases cutting speed with self-centering to prevent walking, and clears chips faster for a smoother operation
• 【Tri-Flat Shank & Straight Flute Design】The three-flat (tri-flat) shank offers maximum anti-slip grip in drill chucks, even under high torque. Paired with a robust two-flute straight groove design, it provides stable chip removal and consistent performance in thin-gauge metal, aluminum, and plastic
