It features a 9.50 mm diameter, a 140-degree R-thinned point for improved self-centering and reduced thrust, and a WD1 coating that extends tool life in demanding applications. The straight-cylindrical shank measures 10.00 mm in diameter, and the overall length is 103.00 mm with a 61.00 mm flute length. A regular spiral with two flutes provides efficient chip evacuation. Coolant-through capability supports deep-hole and interrupted-cut work. This drill is suited for machinists, toolroom technicians, and CNC operators running production or maintenance work on steel and cast iron components.\u003c\/p\u003e\n\u003cp\u003eThe HP255-3740 is engineered for use in steel, alloy steel, and cast iron workpieces, covering ISO material codes P and K. Application coverage includes blind holes, cross holes, standard drilling, and self-centering entry without a spot drill in many setups. The 5xD flute-to-diameter ratio supports moderate-depth bores in a single pass. It fits standard drill chucks and collet holders that accept a 10.00 mm straight shank, making it compatible with CNC machining centers, drill presses, and manual lathes commonly found in job shops and manufacturing facilities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard ferrous materials\u003c\/li\u003e\n  \u003cli\u003eWD1 coating reduces friction and extends edge life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e140-degree R-thinned point promotes self-centering and lowers axial cutting force\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip flushing in blind and cross-hole applications\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration with R-thinning maintains core strength while reducing walk\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.006 to +0.021 mm delivers consistent hole sizing\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 (ISO material codes P and K).

Power down and lock out the spindle before changing tooling. When running coolant-through, verify that the machine tool's coolant supply pressure is within the range recommended for the holder and spindle in use. Solid carbide drills are brittle — avoid interrupted side loads and do not use them to ream or enlarge existing holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 9.50 mm (0.3740 inches)\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\u003eOverall Length (OAL)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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: HP255\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.21 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: HP255-3740\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730184798514,"sku":"HP255-3740","price":174.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/572ef8849892055a6801dc3158bc150f_8defbd20-6c84-48ca-a5cd-cf55a1a23630.jpg?v=1788713080","url":"https:\/\/voomisupply.com\/products\/osg-hp255-3740-solid-carbide-jobber-drill-9-50-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
