Drilling multiple hole sizes through sheet materials typically requires frequent bit changes and risks ragged edges — a step drill bit resolves both problems with a single, progressive-cutting tool. The Draper 53871 Step Drill Bit covers a range of 4 to 30mm in precise 2mm increments, with each step clearly marked at graduations of 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, and 30mm, allowing the operator to stop at the exact diameter required without measuring. Manufactured from high-speed steel and correctly hardened for extended service life, the bit is suitable for drilling into steel, brass, copper, aluminium, wood, and plastics. The hardening process ensures the cutting edges retain their geometry through repeated use across this variety of materials. The Draper 53871 is supplied display packed, making it straightforward to store or present on a retail peg. It is well suited to workshops, electricians, and sheet-metal fabricators who regularly require clean, accurately sized holes across a broad diameter range from a single tool.
