It measures 3.50 mm in diameter with an overall length of 66.00 mm and a flute length of 28.00 mm, giving a 5xD flute-to-diameter ratio suited for moderate-depth holes. The 140-degree point angle with R-thinned web geometry reduces thrust and promotes self-centering at entry. A WD1 coating provides wear resistance and thermal protection during aggressive feed rates. The straight-cylindrical shank measures 6.00 mm in diameter for secure chuck retention. This drill is intended for use by machinists, toolroom technicians, and maintenance professionals working on ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThe HP245-1378 is built for applications including blind hole drilling, cross hole drilling, general drilling, and self-centering operations on steel and cast iron workpieces. Its regular spiral flute geometry and right-hand cutting direction make it compatible with conventional CNC machining centers, drill presses, and handheld power tools with appropriate chuck capacity. The tapered web configuration and R-thinned point are particularly well suited for precision entry on flat or curved ferrous surfaces without a center punch. This is a single-piece packaged drill from the OSG HP245 series, targeting production and maintenance environments where consistent hole quality in ferrous materials is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and extended tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eWD1 coating for improved wear resistance and heat management\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle with R-thinned web for reduced thrust and self-centering entry\u003c\/li\u003e\n  \u003cli\u003e5xD flute-to-diameter ratio supports blind hole and cross hole applications\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 6.00 mm shank fits standard drill chucks and tool holders\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral flute geometry compatible with conventional spindle rotation\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. Primary workpiece material codes P and K apply. Suitable for use in CNC machining centers, drill presses, and similar equipment accepting a 6.00 mm straight-cylindrical shank. Part of the OSG HP245 series covering the 3.00 mm to 4.00 mm diameter range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSolid carbide drill bits should be installed and removed by qualified machinists or toolroom technicians using a properly sized chuck or collet rated for the 6.00 mm shank diameter. Ensure the spindle and workpiece are fully secured before starting the cut. Carbide is brittle — avoid lateral loading, interrupted cuts without appropriate feed rate adjustments, or re-chucking with worn or damaged tool holders. Inspect the cutting edge and coating condition before each use; carbide tooling does not tolerate the same regrind cycles as high-speed steel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3.50 mm (0.1378 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\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\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 by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.004 to +0.016 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\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: 0.065 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: HP245-1378\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739147239730,"sku":"HP245-1378","price":75.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17fac3bcdd49fd228104c77863b3f6e3_1a7f2887-5fdc-418b-8813-a1d5d03c6b26.jpg?v=1788810313","url":"https:\/\/voomisupply.com\/products\/osg-hp245-1378-solid-carbide-jobber-drill-3-50-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
