It carries a 6.8 mm (0.2677 inch) diameter, a 140-degree point angle with R-thinned web geometry, and a WD1 coating for extended tool life under demanding cutting conditions. The spiral flute configuration promotes efficient chip evacuation, and the coolant-through design supports high-feed applications in production environments. This bit is sold individually and suited for use by machinists, toolroom technicians, and CNC operators working in job shop or manufacturing settings.\u003c\/p\u003e\u003cp\u003eThe HP255-2677 is built for drilling steel, alloy steel, and cast iron in applications that include blind hole drilling, cross hole drilling, general drilling, and self-centering operations. The 5xD flute-to-diameter ratio supports deeper penetration without sacrificing chip control. The straight-cylindrical shank with an 8.00 mm shank diameter seats securely in standard drill chucks and collet holders. This bit is a strong fit for CNC machining centers and production drilling fixtures where consistent hole quality and tight diameter tolerance are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003eWD1 coating reduces friction and extends cutting life in steel and cast iron\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with R-thinned web for reduced thrust and accurate self-centering\u003c\/li\u003e\n\u003cli\u003eCoolant-through design compatible with through-spindle coolant systems\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute with tapered web for consistent chip flow in blind and cross holes\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.006 to +0.021 mm for controlled fit applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct application drill bit for use in standard drill chucks, collet holders, and CNC spindles accepting an 8.00 mm straight-cylindrical shank.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit. Confirm the shank is fully seated and the chuck or collet is torqued to the toolholder manufacturer specification before starting a cut. Use through-spindle or external coolant at the recommended flow rate for the workpiece material to prevent premature edge wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.8 mm (0.2677 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 91.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53.00 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\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\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: R-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\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\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eSeries\u003c\/strong\u003e: HP255\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.091 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: HP255-2677\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51749330059570,"sku":"HP255-2677","price":143.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a13decfd42daf117849bd0f0c5844fb0.jpg?v=1788904602","url":"https:\/\/voomisupply.com\/products\/osg-hp255-2677-solid-carbide-jobber-drill-bit-6-8-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
