It cuts at 17\/32 inch (13.50 mm) diameter with a 140-degree split point and an R-thinned web for reduced thrust and improved centering. The straight-cylindrical shank seats securely in standard drill chucks and quick-change holders. Two spiral flutes with a tapered web configuration evacuate chips efficiently during through-hole and blind-hole operations. At 0.376 pounds, this is a compact, rigid tool built for production environments where tight tolerances and consistent hole quality are required.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for machining steel, alloy steel, and cast iron in both job shop and production settings. The screw machine length body keeps overhang short, improving rigidity and reducing deflection when drilling on CNC machining centers, turret lathes, and manual drill presses. The 3xD flute-to-diameter ratio is well matched to shallow-to-moderate depth holes typical in screw machine and turning center work. Machinists and tool crib personnel handling Series HP253 tooling will find this bit a direct fit for ferrous material applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and long tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree drill point angle reduces thrust and improves self-centering\u003c\/li\u003e\n\u003cli\u003eR-thinned web minimizes cutting resistance at entry\u003c\/li\u003e\n\u003cli\u003eTapered web configuration with regular spiral flutes for consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eScrew machine length body reduces overhang and deflection\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.007 to +0.025 mm for controlled hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for drilling steel, alloy steel, and cast iron as part of the OSG HP253 series screw machine length carbide drill line.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine fully stopped and locked out per facility safety procedures. Seat the straight-cylindrical shank fully into the holder or chuck and verify runout before beginning a cut. Carbide tooling is brittle — avoid interrupted cuts or side-loading that exceed the tool's design parameters. Consult the machine manufacturer's recommended feeds and speeds for solid carbide drills in the workpiece material being machined.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 17\/32 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (mm)\u003c\/strong\u003e: 13.50 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 Length\u003c\/strong\u003e: 60.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.007 to +0.025 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.25 inches L x 0.90 inches W x 0.85 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.376 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HP253\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: HP253-5311\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728186868018,"sku":"HP253-5311","price":245.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28449fa99ca46be7c04de7543621f9d1_0279ce97-ca8c-4c2b-9d95-019079d85849.jpg?v=1788689181","url":"https:\/\/voomisupply.com\/products\/osg-hp253-5311-screw-machine-drill-bit-17-32-inch-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
