It measures 8.50 mm (0.3346 inch) in diameter with an overall length of 103.00 mm and a flute length of 61.00 mm. The 140-degree split point with R-thinned web geometry promotes self-centering and reduces the thrust force needed to start a hole. A WD1 multi-layer finish improves wear resistance and tool life in demanding ferrous materials. The straight-cylindrical shank measures 10.00 mm in diameter and seats securely in standard drill chucks and tool holders. This bit is sold individually and is suited for use by machinists, tool-and-die technicians, and production drilling operators.\u003c\/p\u003e\n\u003cp\u003eThe HP245-3346 is built for applications in steel and cast iron where hole accuracy and tool life are the primary concerns. Its 5xD flute-to-diameter ratio provides chip clearance in deeper blind-hole and cross-hole scenarios without requiring through-coolant capability. Typical applications include blind hole drilling, cross-hole intersections, and general production drilling in P and K material groups as classified under ISO workpiece material codes. The regular spiral flute geometry and right-hand cutting direction make it compatible with conventional CNC machining centers and manual drill presses running standard spindle rotation.\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\u003e140-degree point angle with R-thinned web for self-centering and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eWD1 multi-layer coating extends tool life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e5xD flute length supports chip evacuation in blind and cross-hole drilling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 10.00 mm shank fits standard chucks and shrink-fit holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute for conventional spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling steel, alloy steel, and cast iron workpieces in ISO material groups P and K.

Secure the shank fully in the tool holder or chuck before operation and verify runout is within acceptable limits, as carbide is brittle and sensitive to side-loading. Do not use damaged or improperly seated tooling. Follow machine-specific speed and feed guidelines for solid carbide drills in the applicable workpiece material; consult the OSG HP245 series cutting data recommendations for starting 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: 8.50 mm (0.3346 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 103.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 61.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10.00 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\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: WD1 Multi-Layer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\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\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\u003eSeries\u003c\/strong\u003e: HP245\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\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: HP245-3346\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51729013539122,"sku":"HP245-3346","price":120.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17fac3bcdd49fd228104c77863b3f6e3_328f59fc-56aa-423f-8214-80e8e9b033ef.jpg?v=1788698833","url":"https:\/\/voomisupply.com\/products\/osg-hp245-3346-solid-carbide-jobber-drill-bit-8-50mm","provider":"Voomi Supply","version":"1.0","type":"link"}
