Built to DIN 1897 standards, this bit features a 0.2323-inch (5.90 mm) diameter, a 118-degree four-facet split-point geometry, and a web-thinned tapered web configuration that reduces thrust and improves chip evacuation. The M35 cobalt steel construction provides elevated heat resistance for cutting harder and abrasive workpiece materials. It carries a bright, uncoated finish and a right-hand cutting spiral flute. Licensed HVAC, plumbing, and mechanical tradespeople who drill through aluminum components and thin-gauge materials will find this bit well-suited to repetitive production-style drilling tasks.\u003c\/p\u003e\u003cp\u003eThis stub-length drill bit is optimized for applications where rigidity and minimal deflection are critical. The shortened flute length compared to jobber-length bits makes it especially effective in tight clearances and for spot-drilling operations. The primary rated workpiece material is aluminum, though the M35 cobalt grade extends service life across a range of non-ferrous and ferrous materials. It is sold and packaged individually, with a straight-cylindrical shank that fits standard three-jaw drill chucks and collet-style toolholders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM35 cobalt steel construction for improved heat and wear resistance over standard HSS bits\u003c\/li\u003e\n\u003cli\u003eFour-facet split-point tip with web thinning reduces walking and lowers required thrust force\u003c\/li\u003e\n\u003cli\u003eStub-length body provides increased rigidity and reduced deflection versus jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand spiral flute with regular helix optimized for aluminum and similar non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish allows easy visual inspection of cutting edge condition\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or production-use drill bit conforming to DIN 1897 stub-length standards, fitting any drill chuck or collet toolholder accepting a 5.90 mm straight-cylindrical shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by a machinist, tool and die technician, or trade professional in any drill press, hand drill, or CNC spindle accepting the straight-cylindrical shank. Ensure the work surface is secured and the chuck is fully tightened before operation. Use appropriate cutting fluid or lubrication for the target workpiece material to extend cutting-edge life. Inspect the cutting edges for wear before each use and replace if chipping or rounding is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2323 inches (5.90 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.598 inches (66.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.102 inches (28.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.754 inches (19.15 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5.90 mm straight-cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Four Facet, Split\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: Spiral, Regular Helix\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M35)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright, Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine Length)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5524\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.026 pounds\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: 9055240059000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51733613379890,"sku":"9055240059000","price":17.3,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/732d67d258fdd6a2f3c8023bc542e855.jpg?v=1788756923","url":"https:\/\/voomisupply.com\/products\/guhring-9055240059000-cobalt-stub-drill-bit-0-2323-in","provider":"Voomi Supply","version":"1.0","type":"link"}
