Built from M2 HSS with a black oxide finish, it covers 10 step sizes ranging from 3\/16 inch up to 1-3\/8 inches in 1\/16-inch increments. The straight flute geometry and quick-change hex shank make it compatible with standard hex-drive chucks and quick-change driver systems. At 2-27\/32 inches overall length and 0.44 pounds, it is sized for hands-on work in sheet metal, electrical panels, junction boxes, and light structural steel. HVAC techs, electricians, and plumbers reach for this bit when punching clean, step-sized holes through thin-gauge material.\u003c\/p\u003e\u003cp\u003eThis step drill bit is suited for general-purpose and multipurpose trade applications. Electricians use it to open knockout holes in enclosures and panel boxes. HVAC technicians use it when field-fabricating sheet metal connections or drilling through ductwork flanges. Plumbers use it to size holes in framing and light gauge materials. The 1\/8-inch step length keeps each diameter transition controlled and reduces burr formation, cutting down on secondary finishing work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM2 high-speed steel construction handles repeated use in sheet metal and thin steel\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating reduces friction and provides light corrosion resistance\u003c\/li\u003e\n\u003cli\u003e10 step sizes from 3\/16 to 1-3\/8 inches in 1\/16-inch increments\u003c\/li\u003e\n\u003cli\u003eQuick-change hex shank with one flat for secure chuck engagement\u003c\/li\u003e\n\u003cli\u003eStraight flute design with 1\/8-inch step length for controlled, clean cuts\u003c\/li\u003e\n\u003cli\u003eSingle tool replaces multiple standard twist bits for common trade hole sizes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard hex-drive chucks and quick-change driver systems that accept a 7\/16-inch hex shank.

Always disconnect power and de-energize any electrical panel or enclosure before drilling into it. Secure the workpiece before drilling to prevent rotation and use appropriate eye protection. Avoid forcing the bit through material thicker than the step length to prevent heat buildup and premature wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel (M2)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Hole Sizes\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Hole Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Hole Diameter\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStep Increments\u003c\/strong\u003e: 1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStep Length\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Hex Quick Change\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flats\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-27\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.44 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HSTH-OX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Multipurpose General Purpose\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: SD6560858\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51730414993714,"sku":"SD6560858","price":218.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_4a414774-d9ea-4f0f-bc6c-39416c87d5e7.jpg?v=1788717068","url":"https:\/\/voomisupply.com\/products\/hertel-sd6560858-step-drill-bit-10-step-hss-hex-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
