Built on OSG's HP255 series platform, it features a 5.1 mm diameter, a 140-degree point angle with R-thinned web geometry, and a WD1 coating optimized for extended tool life in demanding applications. The straight-cylindrical shank measures 6 mm in diameter, and the overall length is 82 mm with a flute length of 44 mm. The two-flute, regular spiral design promotes efficient chip evacuation. This bit is suited for machinists, tool-and-die professionals, and production operators who require consistent, repeatable hole quality in hard materials.\u003c\/p\u003e\n\u003cp\u003eThe HP255-2008 is engineered for drilling steel, alloy steel, and cast iron in applications including blind hole drilling, cross hole drilling, through drilling, and self-centering operations. The coolant-through design supports internal coolant delivery, making it compatible with CNC machining centers and drilling stations equipped with coolant-through spindles. The 5xD flute-to-diameter ratio accommodates moderate depth drilling without excessive chip packing. This bit targets production environments where tool consistency and material compatibility with P and K workpiece material codes are priorities.\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\u003eWD1 coating for improved lubricity and extended tool life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e140-degree point angle with R-thinned web for reduced thrust and improved self-centering\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design compatible with internal coolant delivery systems\u003c\/li\u003e\n  \u003cli\u003eRegular spiral, two-flute geometry at 5xD ratio for efficient chip evacuation in moderate-depth holes\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 6 mm shank for standard collet and chuck compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and multi-spindle drilling equipment with standard collets or chucks accepting a 6 mm straight shank. Rated for primary workpiece materials classified under ISO material codes P (steel, alloy steel) and K (cast iron).\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and operation should be performed by qualified machinists or CNC operators familiar with carbide tooling. Secure the shank fully in the collet or chuck to the manufacturer-recommended engagement depth before operation. Carbide tooling is brittle — avoid side loading, interrupted cuts, or re-chucking a worn tool without inspection. When using the coolant-through feature, confirm coolant pressure and flow rate are appropriate for the spindle setup before running.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.1 mm (0.2008 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 82 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 44 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint 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 by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: WD1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.004 to +0.016 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HP255\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.051 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: HP255-2008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737873875250,"sku":"HP255-2008","price":97.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c431f9aac87ef5b829734ef0efd0e158.jpg?v=1788794708","url":"https:\/\/voomisupply.com\/products\/osg-hp255-2008-solid-carbide-jobber-drill-bit-5-1mm","provider":"Voomi Supply","version":"1.0","type":"link"}
