Built from cobalt high-speed steel with a TiN (titanium nitride) coating, it delivers extended tool life and improved wear resistance compared to standard HSS tooling. The 118-degree faceted point with web thinning promotes accurate hole entry and reduces thrust force. At 0.9840 inches overall length with a 0.0114-inch decimal diameter, this bit is suited for machine-tool applications where tight tolerances and repeatability are critical. It follows DIN 1899 specification and is manufactured to a diameter tolerance of +0.000 to -0.004 mm.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is used in precision machining environments where small-diameter holes are required in aluminum, non-ferrous metals, and titanium alloys. The spiral flute geometry with a 5xD flute-to-diameter ratio promotes chip evacuation in shallow-depth applications. Maximum drilling depth is 0.0580 inches (1.47 mm). The straight-cylindrical shank with a 1.00 mm shank diameter fits standard precision collets and drill chucks used in CNC machining centers, drill presses, and bench-top precision equipment. It ships individually but requires a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction with TiN coating for extended tool life in abrasive and hard materials\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted drill point with web thinning for accurate entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eWire gauge size 84 — 0.0114 inch decimal diameter\u003c\/li\u003e\n  \u003cli\u003eSpiral flute, regular spiral type, 5xD flute-by-diameter ratio for controlled chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank, 1.00 mm diameter, fits standard precision collets\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 1899 specification with tapered web configuration\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for primary use in aluminum and non-ferrous materials (material codes K, M, N, P) and secondary use in titanium alloys (material code S).

Ensure the spindle and work-holding fixture are fully stopped and de-energized before changing tooling. At 0.0114-inch diameter, the bit is highly susceptible to breakage from misalignment, excessive feed rate, or runout — verify collet concentricity before use. Coolant-through is not supported; use external cutting fluid or mist cooling appropriate to the workpiece material.\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: 84\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0114 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.9840 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\u003eTool Material\u003c\/strong\u003e: Cobalt\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\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\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 Length\u003c\/strong\u003e: 1.90 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.0580 inches (1.47 mm)\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\u003ePoint Type\u003c\/strong\u003e: Faceted\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: 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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 1899\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 660\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 9006600002900\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51755020026162,"sku":"9006600002900","price":305.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/920bd7507fd2ce78448e27b7a469fe57.jpg?v=1788950522","url":"https:\/\/voomisupply.com\/products\/guhring-9006600002900-micro-drill-bit-size-84-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
