It covers 13 hole sizes ranging from 1\/8 inch to 1\/2 inch in 1\/32 inch increments, eliminating the need to swap bits between each hole size. Step drill bits like this one are used in sheet metal, conduit knockout work, and thin-material drilling applications where clean, burr-free holes are required. Electricians, HVAC technicians, and plumbers commonly keep a step bit in their service kit for field drilling of panels, enclosures, and ductwork.\u003c\/p\u003e\u003cp\u003eThis bit is suited for use in residential and light commercial trade work. Typical applications include drilling pilot and clearance holes in sheet metal panels, junction boxes, electrical enclosures, and thin-gauge steel or aluminum. The 1\/32 inch step increment progression allows the technician to achieve a precise hole diameter by stepping up gradually rather than committing to a fixed bit size. Sold individually as a single unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e13 hole sizes in a single bit, from 1\/8 inch to 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e1\/32 inch increments allow precise diameter control\u003c\/li\u003e\n\u003cli\u003eEliminates bit changes when drilling multiple hole sizes\u003c\/li\u003e\n\u003cli\u003eSuited for sheet metal, enclosures, and thin-material applications\u003c\/li\u003e\n\u003cli\u003eSold as a single unit (each)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard step drill bit for use in sheet metal, electrical enclosures, and thin-gauge material drilling across residential and light commercial trade applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eStep drill bits are typically used by electricians, HVAC technicians, and plumbers for field drilling tasks. Use with a variable-speed drill at an appropriate speed for the material being drilled. Secure the workpiece before drilling to prevent movement. Avoid applying excessive pressure, which can cause the bit to grab or the material to deform.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size Range\u003c\/strong\u003e: 1\/8 inch to 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncrements\u003c\/strong\u003e: 1\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Hole Sizes\u003c\/strong\u003e: 13\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: 1T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 038548151014\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\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: IR15101ZR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":51343133147442,"sku":"IR15101ZR","price":41.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310499329.jpg?v=1782017652","url":"https:\/\/voomisupply.com\/products\/irwin-ir15101zr-step-drill-bit-1-8-to-1-2-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
