Titanium-coated for long life and smoother drilling Durable titanium coating reduces wear and lowers friction so bits last longer and cut more smoothly through tougher materials like wood and sheet metal. Coating helps maintain sharpness and consistent performance during prolonged use. Versatile set of six step drill bits Six stepped diameters in one bit allow quick drilling of multiple hole sizes without changing tools. Covers a useful range of hole sizes for general woodworking, sheet metal, and light metalwork applications. Serrated edges for clean, accurate holes Serrated cutting edges reduce slipping and produce cleaner holes with less splintering or jagged edges. Ideal for drilling precise openings in panels and thin materials where a neat finish matters. Easy to use and widely compatible Designed to fit most electric drills; simply mount the bit and begin drilling. Works well for both professional tradespeople and DIY projects. Practical uses Installing hardware and fixtures: drill clean holes in door panels, cabinet faces, and trim without chipping. Metal and sheet metal work: create or enlarge holes in HVAC panels, metal enclosures, and automotive sheet components. Electrical and plumbing projects: punch neat access holes for wiring, conduit, or piping through thin wood or metal panels. What you get A set of six titanium-coated step drill bits with serrated cutting edges that fit most electric drills, offering durability, versatile sizing, and precise cutting for a wide range of projects and materials.
