Built from M2 HSS with a black oxide finish, it cuts through sheet metal, thin plate, and similar materials in a single operation. The hex shank with one flat provides positive grip in quick-change chuck systems. Steps increment in 1\/16-inch intervals from 3\/16 inch up to 7\/8 inch, covering 12 discrete hole sizes. The concave flute geometry helps clear chips and reduce heat buildup during drilling. Overall length is 2-5\/8 inches. This bit is a standard tool for electricians, HVAC technicians, plumbers, and sheet metal workers who need precise, clean holes in thin material.\u003c\/p\u003e\u003cp\u003eThis step drill bit is suited for general-purpose multipurpose applications including electrical box knockouts, sheet metal fabrication, conduit entry points, and HVAC equipment panels. The 1\/8-inch step length and 1\/16-inch increment spacing allow controlled, incremental sizing without repositioning the workpiece. The 3\/8-inch hex shank is compatible with standard quick-change drill systems and most 3\/8-inch or larger cordless and corded drills. Weight is 0.17 pounds, making it easy to carry on the job.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12 hole sizes in a single bit: 3\/16, 1\/4, 5\/16, 3\/8, 7\/16, 1\/2, 9\/16, 5\/8, 11\/16, 3\/4, 13\/16, and 7\/8 inch\u003c\/li\u003e\n\u003cli\u003eM2 high-speed steel construction for durability in general-purpose drilling\u003c\/li\u003e\n\u003cli\u003eBlack oxide coating reduces friction and provides basic corrosion resistance\u003c\/li\u003e\n\u003cli\u003eConcave flute design aids chip evacuation during use\u003c\/li\u003e\n\u003cli\u003eHex shank with one flat for secure seating in quick-change systems\u003c\/li\u003e\n\u003cli\u003e1\/16-inch step increments allow precise hole sizing without tool changes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with quick-change chuck systems accepting a 3\/8-inch hex shank.

Use cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat. Center-punch the target location before starting to prevent walking on smooth surfaces. This bit is not rated for thick stock or hardened materials — use it within its intended application range for safe results.\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: 12\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: 7\/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\u003eOverall Length\u003c\/strong\u003e: 2-5\/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: 3\/8 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: Concave\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\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: SD6560650\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51739145503026,"sku":"SD6560650","price":100.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_dc85e200-5352-4237-8193-a48685d031c9.jpg?v=1788810249","url":"https:\/\/voomisupply.com\/products\/hertel-sd6560650-step-drill-bit-12-step-hss-hex-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
