This 6pcs step drill bit set delivers precise, multi-diameter holes in sheet metal, plastic, and wood with a single tool. The titanium nitride coating provides exceptional heat resistance and extends bit life up to 6x over standard HSS bits, while the hexagonal shank prevents slipping in drill chucks for safer, more efficient operation. Features and Benefits
- Titanium Nitride (TiN) Coating - Provides superior hardness and heat resistance for dramatically longer tool life and faster cutting speeds in tough materials.
- Hexagonal Shank Design - Ensures a secure, non-slip grip in drill chucks and impact drivers, maximizing torque transfer and enhancing user safety.
- Precision Ground Flutes - Create clean, burr-free holes with minimal chatter and reduced material tearing for a professional finish.
- 6-Piece Size Range (4-32mm) - Covers a comprehensive selection of common hole diameters, eliminating the need for multiple standard drill bits.
- Straight Groove Pagoda Design - Efficiently clears chips from the cutting area to prevent clogging and maintain consistent drilling performance. Applications
- Electrical and Plumbing Installations - Quickly create clean holes for conduit, pipes, and cables in electrical boxes and sheet metal.
- Automotive and Metal Fabrication - Perfect for enlarging existing holes or drilling precise diameters in body panels, brackets, and thin-gauge metals.
- HVAC Ductwork and Sheet Metal Work - Ideal for producing smooth, accurate holes in ducting, flashing, and aluminum without expensive hole saws.
- General DIY and Woodworking - Versatile for projects requiring stepped holes in plastic, plywood, or for creating pilot holes for hardware.
