This Worfa step drill bit steps up from 4mm to 32mm across multiple sizes, so a single bit in the chuck covers small pilot holes and large openings alike. You drill down to the step you need and stop, which removes the repeated bit changes that break up a job and makes it easier to keep the hole positioned exactly where you marked it.\u003c\/p\u003e\u003cp\u003eIt is made from High-Speed Steel 4241 with a titanium coating for extra durability and heat resistance, and it is rated for cutting through thin iron plates, aluminium, PVC and wood. The stepped shape also protects the material: each step removes a little at a time rather than forcing a full-diameter cut at once, which lowers the stress on thin sheet and helps avoid the cracks and splits that leave a rough finish.\u003c\/p\u003e\u003cp\u003eThe 6.35mm hex shank fits most standard drills, so the bit moves between tools without a compatibility check. Bit edges are sharp, so keep it away from children, handle it by the shank, and let the drill do the cutting rather than pushing hard by hand. Wear eye protection when drilling metal, clamp the workpiece, and let the bit cool before you touch it after a long cut.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProduct Details\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e High-Speed Steel 4241\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating:\u003c\/strong\u003e Titanium coated for durability and heat resistance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBit Sizes:\u003c\/strong\u003e 4mm to 32mm, multiple step sizes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type:\u003c\/strong\u003e 6.35mm hex shank, compatible with standard drills\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications:\u003c\/strong\u003e Thin iron plates, aluminium, PVC, wood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety:\u003c\/strong\u003e Sharp cutting edges; keep away from children and wear eye protection\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Worfa","offers":[{"title":"Default Title","offer_id":51238083199012,"sku":"CJJJCFCF00358-1+2+3style","price":53.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0786\/1269\/3028\/files\/hf_20260810_133834_b767fde3-dc9a-43bf-bc06-56659fd270d3.png?v=1786369729","url":"https:\/\/worfa.com\/products\/step-drill-bit-set-with-multiple-sizes-durable-high-speed-steel-for-precise-drilling","provider":"Worfa","version":"1.0","type":"link"}
