It carries a 31\/64-inch (0.4843 inch) diameter, a 140-degree R-thinned point for self-centering entry, and an overall length of 124 mm (approximately 4.88 inches). The WD1 coating provides enhanced wear resistance and surface finish when cutting through steel, alloy steel, and cast iron. With a 2-flute spiral configuration and a 5xD flute-to-diameter ratio, this bit maintains chip evacuation efficiency across blind hole and cross-hole applications. Licensed machinists, tool-and-die professionals, and general metalworking shops are the primary installers and users of this tooling.\u003c\/p\u003e\n\u003cp\u003eThe HP245-4843 is built for demanding production and maintenance drilling in steel, alloy steel, and cast iron workpieces. It suits blind hole, cross-hole, standard through-hole, and self-centering drilling operations. The straight-cylindrical shank with a 14 mm shank diameter fits standard drill chucks and collet holders used on CNC machining centers, drill presses, and manual lathes. The regular spiral geometry and tapered web configuration make it a reliable choice for repetitive production runs where consistent hole tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and heat resistance in ferrous machining\u003c\/li\u003e\n  \u003cli\u003eWD1 coating extends tool life when drilling steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e140-degree R-thinned point reduces thrust force and promotes self-centering entry\u003c\/li\u003e\n  \u003cli\u003e5xD flute length supports efficient chip evacuation in deeper blind holes\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral, 2-flute design for balanced cutting action\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in steel, alloy steel, and cast iron workpieces.

Ensure the machine spindle and chuck or collet are powered down and fully stopped before mounting or removing the bit. Carbide tooling is brittle and should not be subjected to lateral impact or used in unstable setups that cause vibration or chatter. Verify that spindle speed and feed rate settings match the material and diameter before engaging the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 31\/64 inches (0.4843 inches, 12.30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 124 mm (approximately 4.88 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 77 mm (approximately 3.03 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 14 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.007 to +0.025 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: 0.405 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: HP245-4843\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727390998834,"sku":"HP245-4843","price":352.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17fac3bcdd49fd228104c77863b3f6e3.jpg?v=1788677231","url":"https:\/\/voomisupply.com\/products\/osg-hp245-4843-solid-carbide-jobber-drill-bit-31-64-in","provider":"Voomi Supply","version":"1.0","type":"link"}
