Built to DIN 338 standards, this Series 622 bit features a 130-degree split point and a parabolic flute geometry that promotes efficient chip evacuation and reduced heat buildup during drilling. The bright uncoated finish suits applications where coating compatibility is a concern. At 8.1 mm in diameter (0.3189 decimal inch) with a 4-19\/32 inch overall length, this drill is sized for general-purpose jobber use. It is installed by machinists, tool and die technicians, and maintenance professionals working with drill presses, CNC equipment, and hand-held power drills.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for primary use in aluminum, as well as a range of non-ferrous and general steel workpiece materials (material codes K, N, P). The parabolic flute design with a 5xD flute-to-diameter ratio supports deeper drilling cycles with improved chip clearance. The straight-cylindrical shank diameter of 0.3189 inches fits standard drill chucks and collet holders. It is manufactured to DIN 338 specification and carries a High Performance grade designation from GUHRING, reflecting tighter tolerances and cobalt alloy substrate for elevated heat resistance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction for elevated heat resistance in metalworking applications\u003c\/li\u003e\n  \u003cli\u003e130-degree drill point angle with web-thinned, tapered web for reduced entry force\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry promotes efficient chip evacuation and reduces drill walking\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish maintains dimensional accuracy on non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet systems\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 338 specification for consistent tolerancing across production runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in drill presses, CNC machining centers, and portable power drills accepting a 0.3189-inch straight-cylindrical shank.

Verify spindle speed and feed rate are appropriate for the workpiece material and bit diameter before beginning the drilling cycle. Cobalt drill bits should not be used dry on hardened steel without appropriate cutting fluid, as excessive heat will degrade the cutting edge. Inspect the drill point and flutes for wear or chipping before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.1 mm (0.3189 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-19\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2-15\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.474 inches (62.85 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3189 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 42 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 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 Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: -0.022 to 0.000 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum (K, N, P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 622\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9006220081000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728529785138,"sku":"9006220081000","price":60.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/70b2775ae8ee7835ff57b8065cf4f828.jpg?v=1788692806","url":"https:\/\/voomisupply.com\/products\/guhring-9006220081000-cobalt-jobber-drill-bit-8-1mm","provider":"Voomi Supply","version":"1.0","type":"link"}
