Built to DIN 1899 specification, this Series 660 bit features a 118-degree faceted point with web thinning for clean entry and reduced thrust. The overall length is 0.9840 inches, the cutting diameter is 0.0209 inches (wire size 75), and the straight-cylindrical shank measures 1.00 millimeter in diameter. A titanium nitride (TiN) coating extends tool life by reducing friction and heat buildup at the cutting edge. The right-hand spiral flute geometry evacuates chips efficiently during deep micro-hole operations. This bit is sized for use by machinists, tool-and-die technicians, and precision fabricators who require consistent performance in tight-tolerance work.\u003c\/p\u003e\n\u003cp\u003eThe 9006600005300 is suited for micro-drilling applications in aluminum, non-ferrous metals, and titanium alloys. With a flute-to-diameter ratio of 5xD and a maximum drilling depth of 0.1030 inches, it is appropriate for through-holes and shallow blind holes in thin-section workpieces. Typical applications include printed circuit board fixturing, instrument components, medical device parts, and aerospace detail work where small, accurate holes are required. The tapered web configuration and regular spiral type make it compatible with CNC machining centers and precision drill presses running appropriate spindle speeds for micro-diameter tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt substrate with TiN coating for extended tool life in abrasive and hard materials\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted point with web thinning reduces entry thrust and improves hole accuracy\u003c\/li\u003e\n  \u003cli\u003eWire size 75 diameter (0.0209 inches) for tight-tolerance micro-hole applications\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank (1.00 mm) for secure seating in standard micro-drill chucks and collets\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut spiral flute promotes efficient chip evacuation at depth\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 1899 specification; diameter tolerance held to +0.000 to -0.004 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification micro drill bit for use in CNC machining centers, micro drill presses, and precision hand-piece units accepting a 1.00 mm straight-cylindrical shank.

Verify runout is within tolerance before beginning the drilling cycle, as excessive runout at this diameter will cause immediate tool breakage. Set spindle speed and feed rate according to the workpiece material and the tooling manufacturer recommendations for sub-0.025-inch diameter cobalt tooling. Handle with care during storage and transport to avoid tip damage.\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: 75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0209 inches\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\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 Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\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\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\u003eShank Diameter\u003c\/strong\u003e: 1.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.9840 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.40 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.1030 inches (2.61 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter 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 (Material Code: K, M, N, P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Titanium Alloy (Material Code: S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Number\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\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: 9006600005300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727923151154,"sku":"9006600005300","price":305.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/11aedc6948432e4be3eef458a82196c2.jpg?v=1788684596","url":"https:\/\/voomisupply.com\/products\/guhring-9006600005300-cobalt-micro-drill-bit-0-0209-in","provider":"Voomi Supply","version":"1.0","type":"link"}
