Built to DIN 1899 standards, this Series 301 bit carries a wire gauge size of 83, which corresponds to a decimal diameter of 0.0122 inches. It features a 118-degree faceted point angle with web thinning on a tapered web configuration, promoting accurate entry and clean hole formation. The overall length is 0.984 inches, with a straight-cylindrical shank diameter of 1.00 mm. The bright, uncoated cobalt construction offers solid heat resistance for demanding materials. This bit is sized for use by machinists, tool and die technicians, and precision fabricators working at micro-scale tolerances.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is suited for drilling aluminum as its primary workpiece material, with titanium alloy listed as a secondary compatible material. The 5xD flute-to-diameter ratio and spiral flute geometry support chip evacuation in shallow, precision holes. Maximum drilling depth is 0.076 inches (1.94 mm), making it appropriate for through-holes and blind holes in thin stock, printed circuit board assemblies, small mechanical components, and aerospace or medical fabrication work where tight tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 83 with 0.0122 inch decimal diameter for micro-precision applications\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted point angle with web thinning for accurate, low-thrust entry\u003c\/li\u003e\n  \u003cli\u003eCobalt tool material provides elevated heat and wear resistance versus standard HSS\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for aluminum and titanium alloy workpieces\u003c\/li\u003e\n  \u003cli\u003eSpiral flute with 5xD ratio supports chip removal in shallow-depth holes\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 1899 specification for consistent dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style precision drill bit replacement for applications requiring wire gauge size 83 cobalt micro drills conforming to DIN 1899 Series 301 standards.

Always ensure the spindle and workpiece are secured before operation. Do not exceed the maximum drilling depth of 0.076 inches without retracting to clear chips. Proper spindle speed selection for the workpiece material is critical to avoid bit breakage at this diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 83\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0122 inches\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: Faceted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered with web thinning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.984 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.40 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.076 inches (1.94 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.00 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: 5xD\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.004 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 301\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 1899\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: 9003010003100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51729524785458,"sku":"9003010003100","price":172.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3de42b68d6267df0fd40972578c47e67.jpg?v=1788705706","url":"https:\/\/voomisupply.com\/products\/guhring-9003010003100-micro-drill-bit-wire-83-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
