With a 0.2205-inch (5.60 mm) diameter and a 140-degree split point, this bit delivers fast, accurate entry without center-punching. The R-thinned web reduces thrust load and helps maintain hole location. Coolant-through construction channels fluid directly to the cutting edge, extending tool life in production environments. Two spiral flutes evacuate chips efficiently, making this bit well-suited for CNC machining centers and automated drilling operations where tool reliability and repeatability matter.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is built for machining steel, alloy steel, and cast iron in industrial and production shop applications. The screw machine length profile — shorter than jobber length — provides added rigidity, reducing deflection and chatter in tight-tolerance drilling. The straight-cylindrical shank measures 6.00 mm, compatible with standard collet chucks and drill chucks used on CNC mills, machining centers, and drill presses. It fits the HP253 series product family and is sized in the 0.2000- to 0.2500-inch decimal inch range, covering common close-tolerance hole requirements in metal fabrication and precision machining work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for high rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree drill point angle for fast, self-centering entry on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eR-thinned web reduces axial thrust and improves chip evacuation at the cutting tip\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers fluid directly to the cutting zone for longer tool life\u003c\/li\u003e\n  \u003cli\u003eScrew machine length (3xD flute ratio) provides extra rigidity versus jobber-length bits\u003c\/li\u003e\n  \u003cli\u003eCoated finish improves surface hardness and heat resistance during extended drilling cycles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling steel, alloy steel, and cast iron.

Secure the shank fully within the collet or chuck to the recommended grip depth before torquing the clamping mechanism. Coolant-through tooling requires a machine spindle with internal coolant delivery to utilize the through-coolant feature. Inspect the cutting edges for chipping or wear before each use and replace the bit if damage is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2205 inches (5.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 66.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 28.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.00 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\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\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.004 to +0.016 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size Range\u003c\/strong\u003e: 0.2000 to 0.2500 inches (5.00 to 6.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HP253\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.047 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: HP253-2205\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728225304882,"sku":"HP253-2205","price":87.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/be85b173c54115c995b2a3a2a86a1671.jpg?v=1788689864","url":"https:\/\/voomisupply.com\/products\/osg-hp253-2205-screw-machine-drill-bit-0-2205-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
