Built from solid carbide with a TiAlN coating, it handles demanding production environments where tool life and hole quality matter. The 0.1102 inch (2.80 mm) diameter and compact screw machine length make it well-suited for close-tolerance work on CNC machining centers and automated drilling equipment. The 140-degree split point and R-thinned web reduce thrust and improve centering at entry, while the regular spiral flute geometry supports efficient chip evacuation at production feed rates.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for use in steel, alloy steel, and cast iron. The screw machine length format — shorter than jobber length — increases rigidity and reduces deflection in short-hole applications. It is a common choice in production shops, job shops, and tool rooms running batch work on mill-turn machines, CNC lathes, and vertical machining centers. The straight-cylindrical shank seats directly into standard drill chucks, collet chucks, and hydraulic toolholders without adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN coating extends tool life at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle with R-thinned web reduces entry thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with 3xD flute-to-diameter ratio supports chip clearance in short-hole drilling\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration adds core strength behind the cutting edges\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, straight-cylindrical shank fits standard CNC and manual toolholding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement screw machine length drill bit for production drilling applications in steel, alloy steel, and cast iron workpieces using standard straight-shank drill toolholding systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists and toolroom technicians. Secure the shank fully in a collet, drill chuck, or hydraulic holder and verify runout before committing to production. Ensure the machine spindle is stopped and the tool is locked before any chuck or collet adjustment. Follow the machine manufacturer and OSG series recommendations for feeds and speeds appropriate to the workpiece material — do not extrapolate values from jobber-length tooling, as screw machine geometry alters optimal parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1102 inches (2.80 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 17.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 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\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.002 to +0.012 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\u003eSeries\u003c\/strong\u003e: HP243\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.013 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2 inches L x 0.55 inches W x 0.45 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HP243-1102\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51754456809778,"sku":"HP243-1102","price":48.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0be17eee2f3b604c6f27ff337663449c.jpg?v=1788945572","url":"https:\/\/voomisupply.com\/products\/osg-hp243-1102-screw-machine-drill-bit-0-1102in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
