It covers 9 hole sizes ranging from 1\/4 inch to 3\/4 inch in diameter, with each step measuring 1\/8 inch in length. The 3\/8 inch round shank features three flats to reduce slippage in standard drill chucks. The bright, uncoated finish is suitable for general-purpose use in sheet metal, electrical panels, and conduit work. Licensed electricians, HVAC technicians, and plumbers rely on step bits like this one when punching clean, sized holes through thin-gauge steel and aluminum without needing multiple drill sizes.\u003c\/p\u003e\n\u003cp\u003eThis step drill bit is well suited for trade work that requires precise hole sizing in thin materials such as electrical enclosures, junction boxes, HVAC sheet metal, and plumbing panels. The 9-step progression allows a single bit to cover a wide range of hole diameters commonly needed in residential and light commercial service work. The 1\/8 inch step increments provide consistent sizing control without the need to change bits between passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-speed steel construction for durability in metal drilling applications\u003c\/li\u003e\n  \u003cli\u003e9 hole sizes from 1\/4 inch to 3\/4 inch in 1\/8 inch increments\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch round shank with 3 flats resists chuck slippage\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish for general-purpose use\u003c\/li\u003e\n  \u003cli\u003eSingle bit replaces multiple standard drill sizes for sheet metal work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 3\/8 inch or larger keyed or keyless drill chucks.

Use at moderate drill speeds with consistent feed pressure to maintain clean step edges. Secure the workpiece firmly before drilling to prevent material from spinning. Inspect the bit for wear regularly, as dull steps can cause oversized or ragged holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Hole Sizes\u003c\/strong\u003e: 9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Hole Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Hole Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStep Length\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Round with Flats\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1325 pounds\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SDD43274752\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732932624690,"sku":"SDD43274752","price":86.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e137689f91bb583a41011dd2d0bc5d2a.jpg?v=1788748940","url":"https:\/\/voomisupply.com\/products\/hertel-sdd43274752-step-drill-bit-9-sizes-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
