It features a 6.70 mm (0.2638 inch) cutting diameter, a 140-degree point angle with R-thinned web geometry, and a WD1 coating that improves wear resistance and tool life in demanding applications. The two-flute, right-hand spiral design promotes efficient chip evacuation in both through-hole and blind-hole operations. At 91.00 mm overall length with a 53.00 mm flute length, this drill fits standard toolholders and CNC machining centers used by machinists and tool-and-die professionals in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe HP245-2638 is engineered for drilling in steel, alloy steel, and cast iron. It is suited for blind hole, cross hole, standard drilling, and self-centering applications. The 5xD flute-to-diameter ratio supports deeper penetration while maintaining rigidity. The straight-cylindrical shank measures 8.00 mm in diameter, fitting ER collet chucks and hydraulic toolholders commonly used on CNC machining centers and drill presses in production environments where tight tolerances and repeatable results are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and heat resistance in ferrous workpiece materials\u003c\/li\u003e\n  \u003cli\u003eWD1 coating extends tool life and reduces built-up edge when drilling steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle with R-thinned web reduces entry thrust and improves self-centering\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral fluting promotes consistent chip evacuation in blind and cross-hole applications\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration and regular spiral type maintain cutting stability throughout the flute length\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of plus 0.006 to plus 0.021 mm delivers consistent hole quality within the 6.00 to 7.00 mm size range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThe HP245-2638 belongs to the OSG HP245 series and is compatible with workpiece materials coded P and K, corresponding to steel, alloy steel, and cast iron.

Secure the 8.00 mm straight-cylindrical shank in a properly sized, clean collet chuck or hydraulic holder to the manufacturer-recommended clamping depth before use. Ensure the spindle and coolant supply are off before tool changes. Coolant-through is not supported on this drill; external coolant or mist lubrication should be applied at the cutting zone when drilling steel or cast iron to manage chip evacuation and heat.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.70 mm (0.2638 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: WD1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 91.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0.006 to plus 0.021 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Alloy Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Blind Hole, Cross Hole, Drilling, Self-Centering\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: HP245\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.125 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: HP245-2638\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728589127986,"sku":"HP245-2638","price":92.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17fac3bcdd49fd228104c77863b3f6e3_0a939c7c-e36b-4cba-b400-106c03f88792.jpg?v=1788693699","url":"https:\/\/voomisupply.com\/products\/osg-hp245-2638-solid-carbide-jobber-drill-6-70-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
