Built from cobalt high speed steel with a coated finish, it delivers extended tool life in demanding production environments. The bit features a 130-degree drill point angle with X-thinned web and a tapered web configuration, which reduces thrust and improves chip evacuation. At 0.089 inches (wire size 43) in diameter and 2 inches in overall length, this compact stub-length bit is suited for close-clearance and machine-tool applications. It is installed by machinists, tool and die professionals, and maintenance technicians using standard drill chucks or CNC toolholders.\u003c\/p\u003e\u003cp\u003eThis bit is intended for drilling operations in steel and alloy steel workpieces, including production drilling on screw machines, turret lathes, CNC mills, and drill presses. The screw machine length (stub length) profile reduces deflection and improves hole accuracy in short-depth applications. The 3xD flute-to-diameter ratio and regular spiral flute geometry make it a practical choice for high-cycle production environments where tool rigidity and repeatability matter. It is sold individually and is appropriate for professional shop and field maintenance use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCobalt high speed steel construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle with X-thinned web reduces entry thrust on tough steel workpieces\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with regular spiral flute for standard chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eScrew machine (stub) length minimizes deflection in close-clearance and machine-tool setups\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0 to -0.014 mm for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use drill bit for screw machines, CNC machining centers, turret lathes, and drill presses accepting a straight-cylindrical shank at 0.089 inches diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or maintenance technicians using a standard keyed or keyless drill chuck or collet system rated for the shank diameter. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify chuck or collet runout is within acceptable limits to preserve diameter tolerance. Cutting speed and feed rate should be set according to the workpiece material and the cobalt HSS grade recommendations for the specific machine being used.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.089 inches (Wire Size 43 \/ 2.26 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.75 inches (19.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 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\u003eTool Material\u003c\/strong\u003e: Cobalt High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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, X-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0 to -0.014 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.005 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10089005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727504474418,"sku":"10089005","price":33.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ef55aff7a33c6052ef5ec8c162c32614.jpg?v=1788678636","url":"https:\/\/voomisupply.com\/products\/osg-10089005-screw-machine-drill-bit-0-089-in-cobalt-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
