It carries a TiAlN (titanium aluminum nitride) coating that extends cutting edge life by reducing heat buildup and resisting wear at elevated temperatures. The bit is wire size 45, which corresponds to a decimal diameter of 0.0820 inches, and features a 135-degree split point for fast penetration and reduced walking on entry. With an overall length of 2.125 inches and a flute length of 1.125 inches, it fits standard drill chucks and is sized for precision work in tight clearances. This is a right-hand cutting tool intended for professional trade and industrial use.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for holemaking in stainless steel, hardened materials, and other ferrous alloys that generate high cutting temperatures. The heavy-duty grade cobalt steel construction handles the heat and stress that would degrade standard high-speed steel bits. Typical applications include mechanical, HVAC, and plumbing fabrication work where accurate small-diameter holes are required in tough base materials. The split point geometry allows drilling without a center punch on most surfaces, which speeds up workflow on the job site or in the shop.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt steel construction rated for stainless steel and hardened materials\u003c\/li\u003e\n\u003cli\u003eTiAlN coating reduces heat and extends tool life in high-temperature cutting\u003c\/li\u003e\n\u003cli\u003e135-degree split point minimizes walking and reduces entry force\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, jobber-length series for standard drill press and hand drill use\u003c\/li\u003e\n\u003cli\u003eWire size 45 decimal diameter of 0.0820 inches for precision small-diameter holes\u003c\/li\u003e\n\u003cli\u003eHeavy-duty grade classification for demanding production and field applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style jobber drill bit compatible with standard 3-jaw drill chucks accepting a 0.0820-inch round shank, suitable for drill presses, hand drills, and CNC drilling applications requiring wire size 45 tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall and remove drill bits only when the drill or drill press is fully powered down and the chuck is stationary. Secure the shank fully in the chuck jaws and verify concentricity before operation. Use appropriate cutting fluid or coolant when drilling stainless steel or hardened materials to prolong tool life, even though this bit does not have through-coolant capability. Eye protection and proper workpiece clamping are required per standard shop safety practices.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 45\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0820 inches\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 Point\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: Heavy Duty\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0820 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Jobber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDouble Margin\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Hardened Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 4140372\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732417806642,"sku":"4140372","price":70.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/19e838feb5527e811c8356c884c10dc5.jpg?v=1788742573","url":"https:\/\/voomisupply.com\/products\/hertel-4140372-cobalt-jobber-drill-bit-wire-45-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
