Built from cobalt high-speed steel and finished with a titanium nitride (TiN) coating, it delivers extended tool life and resistance to heat buildup during cutting. The drill measures 0.0122 inches (0.31 mm) in diameter with an overall length of 0.984 inches. The 118-degree faceted point geometry, combined with a web-thinned and tapered web configuration, promotes accurate entry and reduces thrust. Right-hand spiral fluting evacuates chips efficiently in short-run micro drilling operations. This bit is intended for use by machinists, tool-and-die technicians, and precision fabricators working in production or maintenance environments.\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 material application. The straight-cylindrical shank with a 1.00 mm shank diameter fits standard micro drill chucks and collet holders. Maximum drilling depth is 0.076 inches (1.94 mm), making it appropriate for shallow through-holes and blind holes in thin stock, small components, PCB assemblies, and precision metalwork where wire gauge sizing is required. The 5xD flute-by-diameter ratio supports controlled chip evacuation over the full drilling depth.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire gauge size 83, 0.0122-inch diameter for tight-tolerance micro drilling\u003c\/li\u003e\n  \u003cli\u003eCobalt construction provides heat resistance and wear life beyond standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiN coating reduces friction and extends cutting edge life\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted point with web thinning for accurate entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with 5xD flute ratio for chip clearance in shallow holes\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 1899 specification for micro drill geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard micro drill chucks and collet holders accepting a 1.00 mm straight-cylindrical shank. Primary workpiece material compatibility is aluminum; secondary compatibility includes titanium alloy.

Secure the shank fully in the collet or chuck before operation and verify that runout is within acceptable tolerance for the diameter class. At 0.0122 inches, this bit is extremely fragile — avoid side loading and use only the rated maximum drilling depth of 0.076 inches per pass. No coolant-through capability; external misting or flood coolant directed at the cutting zone is recommended when drilling titanium alloy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: 83\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0122 inches\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\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: Web-Thinned, Tapered\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: Spiral, 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\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\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.004 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 660\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: 9006600003100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51752287666482,"sku":"9006600003100","price":305.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/581412af420a4bf7d63b52c176d78bf7.jpg?v=1788927200","url":"https:\/\/voomisupply.com\/products\/guhring-9006600003100-micro-drill-bit-size-83-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
