Built from cobalt steel with an oxide and gold coating, this bit delivers improved heat resistance and extended tool life compared to standard high-speed steel options. The 135-degree split point reduces walking on contact and requires less feed pressure at startup. At 7.125 inches overall length with a 5.1875-inch flute length, it suits standard jobber-length applications across a wide range of power drills and drill presses.\u003c\/p\u003e\u003cp\u003eThis bit is suited for professional tradespeople drilling through ferrous metals, stainless fastener plates, structural steel, and similar hard substrates on job sites and in fabrication settings. The straight cylindrical shank fits standard three-jaw chucks without adapters. The 5\/8-inch diameter size is commonly used for anchor bolt clearance holes, conduit knockouts, and mechanical fastener bores in both residential and light commercial construction work. Two spiral flutes with a regular spiral type provide efficient chip evacuation during drilling operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt construction with oxide and gold coating for heat resistance and extended bit life in hard metals\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces drill walk and lowers required feed pressure at entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction with regular spiral flute for standard power drill and drill press use\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard three-jaw chucks without adapters\u003c\/li\u003e\n\u003cli\u003eTwo-flute design promotes efficient chip clearance during deep drilling\u003c\/li\u003e\n\u003cli\u003e5xD flute-to-diameter ratio provides adequate flute length for most jobber-length drilling tasks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length replacement drill bit suitable for use in standard power drills, drill presses, and magnetic base drills accepting a straight cylindrical shank in the 0.5000 to 0.6500 decimal inch drill bit size range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this drill bit should be performed by qualified tradespeople familiar with rotary cutting tools and machine safety. Secure the shank firmly in a properly sized three-jaw chuck and verify runout before beginning a cut. Always wear appropriate eye protection and ensure the workpiece is clamped or fixed before drilling. Do not exceed the drill press or tool manufacturer recommended speeds for the material being drilled.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating and Finish\u003c\/strong\u003e: Oxide and Gold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 135 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Split\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 5-3\/16 inches (5.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7-1\/8 inches (7.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 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: 42054\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735171989810,"sku":"42054","price":46.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5ba92ef7d79fd7fe9e426007c8327530.jpg?v=1788770036","url":"https:\/\/voomisupply.com\/products\/hertel-42054-cobalt-jobber-drill-bit-5-8-inch-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
