It features a 6.60 mm (0.2598 inch) diameter, a 140-degree R-thinned point for self-centering entry, and a WD1 coating that improves wear resistance and heat dissipation. The two-flute spiral design with a regular helix promotes efficient chip evacuation in blind-hole and cross-hole applications. Overall length is 91.00 mm with a flute length of 53.00 mm and a 5xD flute-to-diameter ratio. The straight-cylindrical shank measures 8.00 mm in diameter. This drill is suited for machinists, tool-and-die shops, and production drilling operations requiring tight tolerances.\u003c\/p\u003e\u003cp\u003eThe HP245-2598 is designed for drilling steel, alloy steel, and cast iron in a range of application types including blind holes, cross holes, and through-hole drilling operations. Its R-thinned point reduces thrust force and promotes self-centering without a center punch in many setups. The 140-degree point geometry is well matched to harder ferrous workpieces where a steeper point angle reduces walking and improves entry accuracy. Typical environments include CNC machining centers and manual drill presses in industrial and job-shop settings.\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\u003eWD1 coating for improved tool life and reduced heat buildup\u003c\/li\u003e\n\u003cli\u003e140-degree R-thinned point with tapered web for self-centering and reduced thrust\u003c\/li\u003e\n\u003cli\u003eTwo-flute regular spiral design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e5xD flute-to-diameter ratio supporting deeper hole applications\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 8.00 mm shank for broad chuck compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in steel, alloy steel, and cast iron workpieces; primary workpiece material codes P and K.

Secure the shank fully within the chuck or collet and verify runout before cutting. Always operate within the machine spindle speed and feed rate recommendations for the workpiece material and drill diameter. Inspect the cutting edges before each use and replace the drill if chipping or excessive wear is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.60 mm (0.2598 inches)\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\u003eDrill Point 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\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\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: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: WD1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: +0.006 to +0.021 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\u003eTool Application\u003c\/strong\u003e: Blind Hole, Cross Hole, Drilling, Self-Centering\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\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: HP245-2598\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51734281388338,"sku":"HP245-2598","price":92.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17fac3bcdd49fd228104c77863b3f6e3_53bb4070-89b9-49da-8756-077afdc7ee1f.jpg?v=1788762274","url":"https:\/\/voomisupply.com\/products\/osg-hp245-2598-solid-carbide-jobber-drill-6-60-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
