Built from high speed steel (HSS) with a bright, uncoated finish, it features a parabolic flute geometry that promotes efficient chip evacuation and reduces heat buildup during operation. The 130-degree split point enters material quickly and resists walking without a center punch. With a straight-cylindrical shank and a 5\/16-inch flute length, this bit fits standard drill chucks and is sized for screw machine (stub) length applications where rigidity and precision matter. It is used by machinists, tool-and-die professionals, and production shop technicians.\u003c\/p\u003e\u003cp\u003eThis drill bit is engineered for screw machine and CNC drilling operations where shorter flute length provides greater rigidity and improved hole accuracy. The parabolic flute with a 3xD flute-to-diameter ratio is particularly effective in aluminum, where chip packing and built-up edge are common concerns. The web-thinned, parallel web configuration reduces thrust force at the tip, making it well suited to high-cycle production environments and close-tolerance hole work. It conforms to DIN 1897 standards for screw machine length drill bits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e130-degree drill point angle for fast penetration and reduced walking\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes efficient chip evacuation in aluminum\u003c\/li\u003e\n\u003cli\u003eWeb-thinned parallel web reduces axial thrust force\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated HSS construction for general-purpose screw machine length drilling\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collets\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 1897 screw machine length drill standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length drill bit per DIN 1897, suitable for use in standard drill presses, CNC machining centers, and screw machines accepting a straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by a qualified machinist or tooling technician. Secure the shank fully in a properly sized collet or drill chuck before operation, and verify chuck runout is within acceptable tolerance for the application. Always wear appropriate eye protection and secure the workpiece before drilling. Follow shop-specific feeds, speeds, and coolant guidelines for the workpiece material and machine type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Parabolic\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: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.2370 inches (6.02 mm)\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 Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.014 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 552\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9005520013200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51749364891954,"sku":"9005520013200","price":89.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bf44b66116d9a564da11164ff7f340d1.jpg?v=1788905041","url":"https:\/\/voomisupply.com\/products\/guhring-9005520013200-screw-machine-drill-bit-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
