It carries a 5 mm diameter with a 140-degree point angle, an R-thinned point for reliable self-centering, and a WD1 coating applied for wear resistance and extended tool life. The overall length measures 82 mm, with a 44 mm flute length and a 6 mm straight-cylindrical shank. Two spiral flutes with a regular spiral configuration clear chips efficiently during through-hole and blind-hole operations. This bit is suited for professional machining environments where precision and repeatability are required.\u003c\/p\u003e\u003cp\u003eThe HP255-1969 is designed for drilling blind holes, cross holes, and through holes in ferrous workpiece materials including steel, alloy steel, and cast iron. The 5xD flute-to-diameter ratio supports deeper hole applications while maintaining rigidity. Coolant-through capability makes it compatible with CNC machining centers and production drilling setups where internal coolant delivery is available. The straight-cylindrical shank seats in standard drill chucks and collet holders without modification.\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 for enhanced tool life in steel and cast iron applications\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with R-thinned web for self-centering entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design compatible with internal coolant delivery systems\u003c\/li\u003e\n\u003cli\u003e5xD flute-by-diameter ratio supports deeper drilling applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in steel, alloy steel, and cast iron workpieces; compatible with standard drill chucks and collet holders accepting a 6 mm straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine powered down and spindle fully stopped. Seat the straight-cylindrical shank fully and evenly in the chuck or collet holder before tightening to the tool manufacturer's holding specifications. Verify coolant-through passages are clear before running internal coolant. Inspect the cutting edge and coating condition before each use; a chipped or worn edge will affect hole tolerance and surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5 mm (0.1969 inches)\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\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\/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\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\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\u003eWeight\u003c\/strong\u003e: 0.045 pounds\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: HP255-1969\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51738867532082,"sku":"HP255-1969","price":91.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ae253f94f339840a15aa8b3a8027cd1.jpg?v=1788805835","url":"https:\/\/voomisupply.com\/products\/osg-hp255-1969-solid-carbide-jobber-drill-bit-5-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
