It features a 7.20 mm (0.2835 inch) diameter, a 140-degree point angle with R-thinned web geometry, and a WD1 coating designed to extend tool life in demanding applications. The two-flute spiral design runs in a right-hand cutting direction with a regular spiral type, and the tapered web configuration supports chip evacuation in both through and blind hole work. Coolant-through capability makes this bit well suited for high-feed, high-speed programs on CNC machining centers and automated drilling equipment. Machinists and tooling specialists working in production environments are the primary users.\u003c\/p\u003e\u003cp\u003eThe HP255-2835 is rated for use in steel, alloy steel, and cast iron, covering ISO material codes P and K. Its 5xD flute-to-diameter ratio gives it the reach needed for deeper holes while maintaining rigidity. Typical applications include blind hole drilling, cross-hole operations, standard drilling, and self-centering entry cuts. The straight-cylindrical shank at 8.00 mm fits standard ER collets and drill chucks used on machining centers, CNC lathes, and drill presses. This bit is a direct fit for shops running the OSG HP255 series tooling program.\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 extends tool life when drilling steel and cast iron\u003c\/li\u003e\n\u003cli\u003e140-degree point angle with R-thinned web reduces entry thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed, high-feed CNC drilling programs\u003c\/li\u003e\n\u003cli\u003e5xD flute length ratio provides depth capability while maintaining stability\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 8.00 mm shank fits standard ER collets and drill chucks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in steel, alloy steel, and cast iron workpieces (ISO material codes P and K).

Verify collet or chuck runout before use, as excessive runout accelerates carbide wear and increases breakage risk. Coolant-through setups require confirmed coolant pressure and flow at the spindle before starting the cut. Do not use this bit as a hand-drill tool — it is intended for rigid, machine-held applications only.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.20 mm (0.2835 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\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\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\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\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\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: 0.095 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: HP255-2835\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728372269362,"sku":"HP255-2835","price":122.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f4eb7485c87ab6c729a79ad7abf7415c.jpg?v=1788690744","url":"https:\/\/voomisupply.com\/products\/osg-hp255-2835-solid-carbide-jobber-drill-7-20-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
