One Set for Multiple Hole Sizes
Need to drill different-sized holes without constantly changing drill bits? This 3-piece Step Drill Bit Set makes metalworking and DIY projects more convenient. With three bits covering a range of 4mm to 32mm, you can choose the right size for everything from small cable openings to larger installation holes.
Three Bits, More Drilling Possibilities
Each bit features multiple cutting steps, allowing you to gradually enlarge holes to the required diameter. The set includes 4–12mm, 4–20mm and 4–32mm sizes, giving you greater flexibility for different drilling tasks without carrying a large collection of individual drill bits.
Titanium-Coated HSS for Reliable Cutting
Made from high-speed steel (HSS) with a titanium coating, these bits are designed for dependable cutting performance and improved wear resistance. The coating helps reduce friction and heat during drilling when used with appropriate speed and pressure.
Quick Hex Shank Connection
The 6.35mm (1/4-inch) hex shank allows convenient fitting into compatible drill chucks and quick-change holders. Switch between bits easily as your project requires different hole diameters.
Designed for Accurate, Versatile Drilling
The 118° split-point tip helps with initial positioning, while the double-flute cutting design supports smooth, controlled cutting. Suitable for electrical installations, sheet metal work, automotive repairs and general DIY projects.
