Each bit is machined from high speed steel (HSS) with a titanium nitride (TiN) coating that reduces friction and extends cutting life. The split-point tip reduces walking at hole entry, allowing for faster starts without a center punch. The 118-degree drill point angle is a standard geometry suited to general-purpose metalworking. This set is built to DIN specification and measured in the inch system, making it a straightforward fit for shops already working in imperial dimensions. Electricians, HVAC technicians, plumbers, and fabricators all reach for step bits when punching knockouts or enlarging existing holes in enclosures and panels.\u003c\/p\u003e\u003cp\u003eStep drill bits in this set cover hole sizing in sheet-metal and light structural applications. With a maximum drill bit size of 30 inches as listed in the supplier data, tradespeople working on electrical enclosures, junction boxes, conduit entry points, duct panels, and similar thin-material substrates will find this set practical for everyday field and shop use. The 3-piece count provides a range of step profiles so one set handles multiple hole-size requirements without a full bit change.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh speed steel construction with TiN coating for extended tool life and reduced heat buildup\u003c\/li\u003e\n\u003cli\u003eSplit-point tip minimizes walking and allows drilling without a center punch\u003c\/li\u003e\n\u003cli\u003e118-degree drill point angle suits general-purpose metalworking applications\u003c\/li\u003e\n\u003cli\u003eBuilt to DIN specification in the inch measurement system\u003c\/li\u003e\n\u003cli\u003e3-piece set provides multiple step profiles for a range of hole sizes\u003c\/li\u003e\n\u003cli\u003eMaximum drill bit size of 30 inches as rated by manufacturer\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose step drill bit set for use in hand-held drills and drill presses capable of accepting step-style bit shanks, suitable for sheet metal, plastic, and light-gauge materials in electrical, HVAC, plumbing, and fabrication 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 knockout and hole-enlarging work in sheet metal enclosures and panels. Always power down and de-energize any electrical enclosure before drilling. Secure the workpiece before beginning to prevent spinning or shifting during the cut. Use appropriate cutting fluid on steel to preserve TiN coating life and maintain cut quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet Type\u003c\/strong\u003e: Step Drill Bits\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drill Bit Size\u003c\/strong\u003e: 30 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 5.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 1.65 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 3.93 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.63 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: SDD43275049\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51731572097330,"sku":"SDD43275049","price":293.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d5355108050c34ebc5bbdc943eab06cd.jpg?v=1788732640","url":"https:\/\/voomisupply.com\/products\/hertel-sdd43275049-step-drill-bit-set-3-pc-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
