Each step bit is made from high speed steel 4241, chosen for its suitability with materials up to 25 degrees hardness such as carbon steel, iron plate, and steel plate. The yellow and black surface treatment provides a clear visual reference while cutting. The set is supplied in a robust aluminium box that keeps the bits organised and protected between uses. Ideal for bench drill use, this set delivers straightforward, reliable performance in workshop environments.\u003c\/p\u003e\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"5-piece high speed steel ladder drill set in aluminium box with step bits from 3\/16 to 1\/2 inch\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US11\/4533\/2025-10-25\/original-image\/3915648913680.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe drill set is built around high speed steel 4241, a material suited to common metalworking tasks. Each bit features a stepped design that allows one tool to create several hole sizes without swapping attachments.\u003c\/p\u003e\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\u003cp\u003eHigh speed steel 4241 is used for all five bits, selected for its ability to cut through carbon steel, iron plate, and steel plate below 25 degrees. The yellow and black surface treatment adds visibility but no specific performance claims are made about wear or longevity. The bits are designed for bench drill use, not hand drilling.\u003c\/p\u003e\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\u003cp\u003eThe set covers a practical range of hole sizes from 3\/16 to 1\/2 inch, with step increments including 1\/8, 5\/32, 7\/32, 1\/4, 9\/32, 5\/16, 7\/32, 3\/8, 13\/32, 7\/16, 15\/32, and 1\/2 inch. This range suits most light to medium metal drilling jobs.
