Built to heavy-duty grade standards, it features a 135-degree split point that reduces walking on contact and lowers the thrust required to start a hole. The oxide and TiN coating improves surface hardness and extends tool life in demanding drilling applications. At 2.5 inches overall length with a 1.4375-inch flute, this bit fits standard drill chucks via its straight-cylindrical shank. The 0.1065-inch diameter corresponds to No. 36 wire gauge sizing. Licensed trades and industrial machinists use this bit for repetitive production drilling where standard HSS tools wear prematurely.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for metalworking applications in HVAC fabrication, electrical panel work, plumbing rough-in, and general mechanical assembly where tight-tolerance holes in steel, stainless, or hard alloy are required. The regular spiral flute evacuates chips efficiently in through-hole and blind-hole operations. The web-thinned, tapered web construction reduces cutting resistance at the center of the bit, making it well suited for hand-held and drill-press use on harder base metals where a standard jobber bit would overheat or dull quickly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 36 wire size, 0.1065-inch diameter for precise small-hole work\u003c\/li\u003e\n\u003cli\u003e135-degree split point with web thinning reduces thrust and prevents walking\u003c\/li\u003e\n\u003cli\u003eCobalt construction with oxide and TiN coating for extended life in hard metals\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with tapered web for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, heavy-duty grade jobber series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard jobber-series drill bit for use in any drill press, CNC drill, or hand-held power drill equipped with a chuck sized for a 0.1065-inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists, millwrights, and licensed trades requiring precision small-diameter holes. Secure the straight shank firmly in the chuck before operation and verify chuck key is removed before powering the tool. Use appropriate cutting fluid or cooling when drilling stainless or hard alloy to prevent overheating and premature coating breakdown. Do not exceed the recommended feed rate for the base material, and allow the split point to fully engage before applying full feed pressure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 36\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1065 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\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\u003eCoating\/Finish\u003c\/strong\u003e: Oxide and TiN\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\u003eFlute Length\u003c\/strong\u003e: 1.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1065 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Jobber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: 04138830\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734370091314,"sku":"04138830","price":40.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4fffe4234a78152a5cdf4a85a1d6ed5b.jpg?v=1788762718","url":"https:\/\/voomisupply.com\/products\/hertel-04138830-cobalt-jobber-drill-no-36-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
