What this tool solves Replace multiple twist bits with one step drill that covers a wide range of hole sizes, reducing bit changes and saving time. Cuts cleaner holes with less vibration than ordinary twist drills, so work is faster and more precise without the need for center punching. Key features and benefits Twelve hole sizes in a single bit: 6mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm — covers most common hole sizes for metal, plastic and wood work. Titanium-coated 4241 high speed steel for improved wear resistance and longer life than uncoated bits. Quick impact tip designed to drill up to twice as fast as the average step drill, improving drilling speed and reducing heat build-up. Smooth operation with reduced shaking; designed to open holes without center punching in many materials. Materials and performance Constructed from 4241 high speed steel with a titanium coating for durability and consistent cutting performance. Effective on acrylic, PVC, wood, aluminium and iron sheets — suitable for a broad range of projects. Practical uses (real-world scenarios) Electrical installation: punch accurate holes in metal junction boxes and panels for conduit or cable glands. HVAC and sheet metal work: create ventilation or access holes in aluminium and iron panels quickly and cleanly. DIY and cabinetry: make clean, progressive holes in acrylic, PVC and wood for fittings, bushings and pass-throughs. How to use (tips) Mount the bit securely in a drill with appropriate speed and steady pressure; the quick impact tip improves entry and cutting. Use moderate RPM for metals and higher RPM for plastics and wood; back off to clear chips regularly for best results. No center punch is usually required; however, on very hard or thin material, a light center mark can aid initial positioning. Specifications Sizes: 6mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm, 60mm Material: 4241 high speed steel Coating: Titanium Suitable for: Acrylic, PVC, wood, aluminium and iron sheets Reliable, durable and versatile — a single step drill designed to simplify hole-making across a range of materials and projects.
