The bit measures 0.1660 inches in diameter with a 3.25-inch overall length and a 2.125-inch flute length. It features a 135-degree split point for self-centering entry with reduced walking, and a TiAlN coating that improves heat resistance and extends tool life in demanding cutting applications. The straight-cylindrical shank fits standard drill chucks without adapters. This bit is suited for machinists, pipefitters, and general trade professionals who drill through tough base metals regularly.\u003c\/p\u003e\n\u003cp\u003eThis jobber drill is designed for production and maintenance holemaking in metal fabrication, mechanical contracting, and industrial service environments. The regular spiral flute and web-thinned, tapered web geometry promote efficient chip evacuation and reduce thrust load during drilling. Right-hand cutting direction is standard for conventional drill press and handheld drilling operations. It is appropriate for use in drill presses, CNC machining centers, and hand-held power drills with a compatible chuck.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNo. 19 wire gauge size, 0.1660 inch diameter for precise hole sizing\u003c\/li\u003e\n  \u003cli\u003eCobalt construction rated heavy duty for drilling hardened and abrasion-resistant metals\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating extends cutting life and improves performance at elevated temperatures\u003c\/li\u003e\n  \u003cli\u003e135-degree split point reduces walking and lowers required feed force\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web geometry aids chip evacuation and reduces drill thrust\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard three-jaw drill chucks directly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard jobber-length drill bit for use in any drill press, CNC machine, or handheld power drill accepting a straight-cylindrical shank of 0.1660 inch diameter.

Use appropriate cutting fluid or coolant for the material being drilled to reduce heat buildup, even though this bit does not support through-coolant. Verify drill speed settings match the workpiece material and bit diameter per standard machining reference charts. Inspect the cutting edges before each use and replace or resharpen when the point shows signs of wear to avoid work hardening the base material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: No. 19\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.1660 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1660 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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: TiAlN\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: 0.19 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 4140133\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749384618290,"sku":"4140133","price":15.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69fe5cccd20f53a68ff72454215c23b9.jpg?v=1788905390","url":"https:\/\/voomisupply.com\/products\/hertel-4140133-cobalt-jobber-drill-bit-no-19","provider":"Voomi Supply","version":"1.0","type":"link"}
