Sized at wire gauge 43 (0.0890 inches decimal), it is ground from high speed steel with a bright, uncoated finish. The standard 118-degree split point and web-thinned tip promote accurate entry and reduce walking on flat surfaces. Overall length is 2.25 inches with a 1.25-inch spiral flute. The straight cylindrical shank seats directly in standard drill chucks without an adapter. This bit is used by machinists, maintenance technicians, pipefitters, and HVAC sheet metal mechanics for production and maintenance drilling operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling steel, cast iron, non-ferrous metals, superalloys, and titanium in both production and maintenance settings. Its jobber-length geometry balances rigidity with reach, making it appropriate for handheld drill motors, drill presses, and CNC drilling operations where a wire-gauge size is specified. The regular spiral flute promotes chip evacuation in through-hole and blind-hole applications. Maximum drilling depth is 1.25 inches per the flute length.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire size 43, 0.0890 inches decimal diameter for precise gauge-size holes\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned tip for clean entry\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction rated for steel, cast iron, non-ferrous metals, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating buildup to alter diameter tolerance\u003c\/li\u003e\n\u003cli\u003eRegular spiral, 2-flute design with tapered web for consistent chip clearance\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank compatible with standard drill chucks\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI standards, Series R10H-R18H\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a general-purpose jobber-length drill bit for use in standard drill chucks accepting a 0.0890-inch straight cylindrical shank.

Secure the workpiece fully before drilling and ensure the chuck is tightened on the shank before operation. Disconnect or de-energize the drill motor before changing bits. Do not exceed the rated maximum drilling depth of 1.25 inches in a single pass without backing out to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 43\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0890 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.0890 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright, Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Drilling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R10H-R18H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 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: PRECISION TWIST DRILL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5997991\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRECISION TWIST DRILL","offers":[{"title":"Default Title","offer_id":51701083373874,"sku":"5997991","price":47.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4691d72f892b92915254364cb4aea851_f8078c9c-d1d6-4c4b-bc40-87887ee6b32d.jpg?v=1788398006","url":"https:\/\/voomisupply.com\/products\/precision-twist-drill-5997991-jobber-drill-bit-43","provider":"Voomi Supply","version":"1.0","type":"link"}
