Built from solid carbide, this bit delivers the rigidity and heat resistance required when drilling hardened steels, cast iron, stainless, and other tough materials. The 140-degree split point geometry reduces walking at entry and lowers thrust force needed to start a hole. At 118.00 millimeters overall length with a 71.00-millimeter flute length, this bit fits standard jobber-length applications. It carries a WD1 coating for added surface hardness and wear resistance. Machinists and tool-and-die professionals are the primary users of this bit in CNC drilling centers and manual drill presses.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for production and job-shop environments where dimensional accuracy and tool life are priorities. The 12.00-millimeter shank diameter seats securely in standard collets and drill chucks. The 5xD flute-to-diameter ratio provides adequate chip evacuation in moderate-depth holes. Diameter tolerance of plus 0.0070 to plus 0.0250 millimeters meets typical close-tolerance fit requirements in metal fabrication and precision machining. It does not include coolant-through capability, so external coolant or cutting fluid application is recommended when drilling heat-sensitive or gummy materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for maximum rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003e140-degree point angle reduces drill walking and entry thrust requirements\u003c\/li\u003e\n\u003cli\u003eWD1 coating improves surface hardness and extends tool life\u003c\/li\u003e\n\u003cli\u003eR-Thinned web for reduced cutting forces at the chisel edge\u003c\/li\u003e\n\u003cli\u003e5xD flute-to-diameter ratio supports chip evacuation in moderate hole depths\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of plus 0.0070 to plus 0.0250 mm for close-tolerance drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber-length solid carbide drill bit for use in CNC machining centers, drill presses, and other rotating tool holders accepting a 12.00-millimeter straight shank, within the 0.4000 to 0.5000 decimal inch diameter range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or tooling professional. Ensure the machine spindle is fully stopped and the tool holder is properly cleaned before seating the shank. Solid carbide bits are brittle compared to high-speed steel and should not be used in setups with excessive runout or lateral loading. External cutting fluid is recommended since this bit does not feature coolant-through passages.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.4646 inches (11.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 118.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 71.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12.00 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\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: WD1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\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: plus 0.0070 to plus 0.0250 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.4000 to 0.5000 decimal inch (10.00 to 12.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: HP245-4646\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51752279245106,"sku":"HP245-4646","price":283.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17fac3bcdd49fd228104c77863b3f6e3_fa732c27-56f0-4a67-a31b-5a631e1bf489.jpg?v=1788927125","url":"https:\/\/voomisupply.com\/products\/osg-hp245-4646-jobber-drill-bit-0-4646-in-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
