It features a 6.50 mm (0.2559 inch) cutting diameter, a 140-degree R-thinned point for self-centering entry, and a WD1 coating for improved wear resistance and heat management. The two-flute spiral configuration with a regular helix and tapered web promotes efficient chip evacuation in a right-hand cutting direction. Overall length is 91.00 mm with a 53.00 mm flute length, and the straight-cylindrical shank measures 8.00 mm in diameter. This drill is suited for production and maintenance environments where precision hole quality and tool life matter.\u003c\/p\u003e\u003cp\u003eThe HP245-2559 is designed for drilling in steel, alloy steel, and cast iron. It performs well in blind hole, cross hole, and through-hole applications, and its R-thinned point geometry reduces thrust force during entry, making it effective for self-centering starts without a center drill in many setups. The 5xD flute-to-diameter ratio supports moderate drilling depths typical of jobber-length work. It is used by machinists, tool-and-die shops, maintenance technicians, and metalworking professionals in both manual and CNC drilling operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eWD1 coating reduces friction and improves wear resistance at the cutting edge\u003c\/li\u003e\n\u003cli\u003e140-degree R-thinned point provides self-centering capability and lower entry thrust\u003c\/li\u003e\n\u003cli\u003eTwo-flute spiral configuration with tapered web for effective chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.006 to +0.021 mm for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling steel, alloy steel, and cast iron workpieces.

Secure the shank fully in a drill chuck or collet to the depth recommended by the toolholder manufacturer before operation. Carbide is brittle compared to high-speed steel — avoid side loading, interrupted cuts without appropriate feed rate adjustments, and impact that can cause chipping. Verify spindle speed and feed rate against the material being drilled before running the tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.50 mm (0.2559 inch)\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\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\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular Helix\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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: +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\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\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: HP245-2559\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51753013838130,"sku":"HP245-2559","price":87.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17fac3bcdd49fd228104c77863b3f6e3_1e243eb2-f6b9-4d86-b6f5-a41ef358cffb.jpg?v=1788932143","url":"https:\/\/voomisupply.com\/products\/osg-hp245-2559-solid-carbide-jobber-drill-6-50-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
