Built to a No. 44 wire gauge size, it measures 0.0860 inches in diameter with a 2.125-inch overall length and a 1.125-inch flute length. The 135-degree split point reduces walking on entry and lowers thrust requirements compared to a conventional 118-degree point. The oxide and TiN coating provides surface hardness and heat resistance for extended tool life in high-cycle production environments. A tapered web with web thinning keeps cutting forces manageable. This bit is sold individually and is intended for use by machinists, maintenance technicians, and trade professionals performing precision drilling tasks.\u003c\/p\u003e\u003cp\u003eThis bit suits applications requiring accurate small-diameter holes in steel, stainless, cast iron, and other difficult-to-machine materials. The straight cylindrical shank seats directly in standard drill chucks, collets, and quick-change tooling systems. The regular spiral flute geometry promotes chip evacuation in through-hole and blind-hole operations. It is appropriate for use in bench drill presses, CNC machining centers, hand-held drill motors, and turret setups where a jobber-length reach is sufficient. The heavy-duty grade cobalt substrate handles elevated cutting temperatures better than standard high-speed steel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 44 wire size, 0.0860-inch diameter for precision small-bore work\u003c\/li\u003e\n\u003cli\u003e135-degree split point reduces thrust and prevents bit walking on entry\u003c\/li\u003e\n\u003cli\u003eCobalt construction handles heat buildup in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eOxide and TiN coating adds surface hardness and extends service life\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web lowers cutting resistance and improves chip flow\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank fits standard chucks and collet systems without modification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-series replacement or direct-use drill bit for any standard drill chuck or collet accepting a 0.0860-inch straight cylindrical shank across benchtop, floor, and CNC drill applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or qualified technician should secure the shank fully in the chuck or collet before operation, verifying runout is within acceptable limits for the application. Power down and de-energize or lock out the machine before changing bits. Coolant-through is not supported on this bit; apply external cutting fluid as needed when drilling hard materials. Follow applicable shop safety codes and machine manufacturer guidelines for spindle speed and feed rate selection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: No. 44\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0860 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, 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: 1.125 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: 0.0860 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Oxide and TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Heavy Duty\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: 0.04 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: 04138913\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51733170979122,"sku":"04138913","price":39.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc3c3be80e77683eb34597754243bf47.jpg?v=1788752208","url":"https:\/\/voomisupply.com\/products\/hertel-04138913-cobalt-jobber-drill-bit-no-44-135-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
