The Beta 425/SP3 stepped drill set is used for drilling and enlarging holes in sheet materials such as steel, aluminium, brass and copper. Each bit has a conical shape with stepped diameters and a split-point tip, allowing for accurate, controlled cutting without changing drills.Here are the main features that support its use:High-Speed Steel (HSS) Construction: Made from HSS to maintain cutting edge sharpness, reduce heat build-up and provide consistent performance across mild steel and non-ferrous metals.Split Point Tip: Self-centring tip design reduces bit wandering on contact, improving precision and removing the need for centre-punching.Progressive Stepped Design: Evenly spaced cutting steps allow gradual enlargement of holes, preventing over-drilling and giving you more control.Laser-Marked Step Indicators: Size markings on each step help you identify the diameter quickly and drill to the exact size without extra measuring.Cylindrical Shank: Straight shank keeps a secure grip in drill chucks, reducing slippage and maintaining stability while drilling.Plastic Carry Case: Keeps the drills protected and organised, making it easier to carry and find the right size when needed.Three Drill Sizes Included: Covers 4 to 30 mm with multiple steps, offering a wide range of hole sizes from a single set.DrillHole RangeStep IncrementLength425/14 12 mm1 mm70 mm425/34 20 mm2 mm85 mm425/64 30 mm2 mm75 mmThis set helps you drill clean, precise holes in sheet materials without switching tools.
