Built to DIN 338 standards, it is designed for high-performance drilling in materials that demand thermal and wear resistance. The bright uncoated cobalt construction provides rigidity and heat tolerance without a coating that could mask wear. Overall length is 5.25 inches with a flute length of 3.4375 inches and a straight-cylindrical shank matching the 0.4039-inch drill diameter. It is suitable for machinists, maintenance technicians, and trade professionals who require consistent, repeatable hole quality in production or field environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is rated for use in aluminum and non-ferrous metals, as indicated by the primary workpiece material codes K, N, and P, which cover aluminum alloys, non-ferrous metals, and certain plastics and composites. The parabolic flute profile supports efficient chip evacuation in these materials, reducing heat buildup and helping maintain hole tolerance. The 5xD flute-to-diameter ratio and web-thinned tapered web reduce thrust force at entry. Maximum drilling depth is 2.819 inches (71.61 mm). This bit is well suited to fabrication shops, HVAC equipment manufacturing, plumbing fixture work, and general maintenance drilling applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLetter Y size at 0.4039 inches decimal equivalent for standard and tight-tolerance drilling\u003c\/li\u003e\n\u003cli\u003eCobalt construction with bright uncoated finish for heat resistance and wear visibility\u003c\/li\u003e\n\u003cli\u003e130-degree point angle with web-thinned tapered web reduces entry thrust force\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry promotes fast, clean chip evacuation in aluminum and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and collet holders\u003c\/li\u003e\n\u003cli\u003eManufactured to DIN 338 specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style jobber length drill bit per DIN 338 Series 622 standards, suitable for use with standard drill chucks and collet systems accepting a 0.4039-inch straight shank.

Secure the workpiece fully before drilling and verify chuck or collet grip on the straight shank before engaging the spindle. Do not exceed the maximum drilling depth of 2.819 inches without retracting to clear chips. Follow applicable shop safety standards and machine manufacturer operating guidelines when selecting feed rate and spindle speed for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: Y\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.4039 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.819 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4039 inches\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eDrill Bit Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum, Non-Ferrous Metals (K, N, P)\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 9006220102600\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732006928690,"sku":"9006220102600","price":104.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/271ab4d0a6f4191baff8ef2a2596b9a8.jpg?v=1788738001","url":"https:\/\/voomisupply.com\/products\/guhring-9006220102600-cobalt-drill-bit-letter-y","provider":"Voomi Supply","version":"1.0","type":"link"}
