The set covers 9 hole sizes ranging from 1\/4 inch to 3\/4 inch, giving technicians a single tool to handle a wide range of opening sizes without swapping bits. The 3\/8 inch shank fits standard drill chucks commonly found on corded and cordless drills used in HVAC, electrical, and plumbing rough-in work. Electricians and HVAC installers rely on step drill bits for punching knock-outs and conduit openings in electrical enclosures and sheet metal ductwork.\u003c\/p\u003e\u003cp\u003eThis step drill bit set is suited for light commercial and residential trade work where clean, burr-free holes are required in thin materials. Common applications include drilling wire and conduit pass-throughs in electrical panels and junction boxes, creating drain and supply line openings in sheet metal, and punching holes in HVAC equipment panels. The 9-step design allows a single bit to cover multiple diameters, reducing the number of tools needed on a service call or installation job.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e9-step design covers hole sizes from 1\/4 inch to 3\/4 inch in a single bit\u003c\/li\u003e\n\u003cli\u003e3\/8 inch shank fits standard drill chucks on corded and cordless drills\u003c\/li\u003e\n\u003cli\u003eStep geometry produces clean, accurate holes in sheet metal and plastic with minimal burring\u003c\/li\u003e\n\u003cli\u003eCompact set reduces toolbox clutter for field technicians\u003c\/li\u003e\n\u003cli\u003eSuitable for electrical, HVAC, and plumbing sheet metal applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 3\/8 inch or larger drill chucks on corded and cordless drills.

Always de-energize electrical panels and equipment before drilling near live components, following NFPA 70 (NEC) lockout\/tagout procedures. Use light, consistent pressure to allow the step geometry to self-center and prevent bit walking. Safety glasses and appropriate hand protection should be worn when drilling sheet metal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size Range\u003c\/strong\u003e: 1\/4 inch to 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Steps\u003c\/strong\u003e: 9\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.063 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 038548101033\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IRWIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10233\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51346233360690,"sku":"10233","price":239.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310499391.jpg?v=1782074731","url":"https:\/\/voomisupply.com\/products\/irwin-10233-unibit-step-drill-bit-set-9-steps","provider":"Voomi Supply","version":"1.0","type":"link"}
