Built from solid carbide with an EgiAs coating incorporating a TiAlN drill tip finish, it delivers extended tool life and thermal resistance in demanding production environments. The bit measures 2.60 mm in diameter (0.1024 decimal inch) with a 140-degree point angle and a 50 mm (1.97 inches) overall length. The R-thinned point geometry reduces thrust and improves centering at entry. Machinists and toolroom professionals working with CNC machining centers, drill presses, and screw machines will find this bit suited to precision hole-making in ferrous materials.\u003c\/p\u003e\u003cp\u003eThe HP243-1024 is part of OSG Series HP243, a high-performance carbide drill line designed for short-length, high-accuracy applications. The screw machine length format provides increased rigidity compared to jobber-length equivalents, making it well suited for close-tolerance work in production machining, job shop environments, and automated equipment. Primary target materials include steel, alloy steel, and cast iron. The 3xD flute-to-diameter ratio and straight-cylindrical shank allow straightforward toolholder compatibility across common collet and chuck systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003eEgiAs coating with TiAlN drill tip finish for thermal protection and extended tool life\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with R-thinned web for reduced entry thrust and improved self-centering\u003c\/li\u003e\n\u003cli\u003eScrew machine length (3xD flute ratio) provides superior rigidity over jobber-length drills\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank at 3.00 mm (0.1181 decimal inch) fits standard collets and chucks\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting, regular spiral, spiral flute geometry for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in steel, alloy steel, and cast iron workpiece materials.

Verify machine spindle and toolholder clearance before use.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine powered down and spindle fully stopped. Secure the shank firmly in the toolholder to the full depth of the collet or chuck to prevent runout and pullout during cutting. Solid carbide drills are brittle and should not be used in machines with excessive spindle runout or play. Consult machine tool documentation and applicable shop safety standards before commencing drilling operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 2.60 mm (0.1024 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 50 mm (1.97 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 15.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3.00 mm (0.1181 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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: EgiAs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Tip Coating\u003c\/strong\u003e: TiAlN\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003ePoint Type\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine (3xD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HP243\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2 inches (L) x 0.5 inches (W) x 0.45 inches (H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241635\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: HP243-1024\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727185576242,"sku":"HP243-1024","price":41.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64c07727321d589a8ab5036dba32ce97.jpg?v=1788674464","url":"https:\/\/voomisupply.com\/products\/osg-hp243-1024-screw-machine-drill-bit-2-60mm-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
