The set covers 12 hole sizes ranging from 3\/16 inches to 7\/8 inches in a single stepped bit, eliminating the need to change bits between sizes. The 1\/8 inch shank is compatible with standard drill chucks. This type of tool is commonly used by HVAC technicians, electricians, and plumbers when punching knock-outs or port holes in panels, junction boxes, sheet metal ductwork, and enclosures.\u003c\/p\u003e\n\u003cp\u003eStep drill bits in this size range are well suited for light-gauge sheet metal work in residential and light commercial applications. Typical install scenarios include drilling conduit knock-outs in electrical panels, punching holes for low-voltage wiring, sizing port openings in HVAC sheet metal, and creating clean-edged holes in plastic enclosures. The progressive step design allows a single bit to replace multiple standard twist bits for thin-material drilling tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e12 hole sizes in one bit, ranging from 3\/16 inches to 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch shank fits standard 3\/8 inch and larger drill chucks\u003c\/li\u003e\n  \u003cli\u003eStep design eliminates bit changes when drilling multiple hole sizes\u003c\/li\u003e\n  \u003cli\u003eProduces clean edges in sheet metal, aluminum, and thin plastics\u003c\/li\u003e\n  \u003cli\u003eCompact set format reduces tool bag clutter on service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard drill chucks accepting a 1\/8 inch shank, suitable for drilling thin-gauge sheet metal, aluminum, and plastic panels common in HVAC, electrical, and plumbing service work.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eStep drill bits are typically used by HVAC technicians, electricians, and plumbers during rough-in and panel work. Always de-energize electrical panels and shut off relevant systems before drilling in or near live components. Use appropriate PPE including eye protection when drilling metal. Apply light, consistent pressure and allow the bit to step through material gradually to avoid walking or overheating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size Range\u003c\/strong\u003e: 3\/16 inches to 7\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Hole Sizes\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Size\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.313 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 038548101040\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 10234\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51343279522098,"sku":"10234","price":282.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310499392.jpg?v=1782019770","url":"https:\/\/voomisupply.com\/products\/irwin-10234-unibit-step-drill-bit-set-12-hole","provider":"Voomi Supply","version":"1.0","type":"link"}
