Built from cobalt high-speed steel and coated with titanium nitride (TiN), it delivers elevated heat resistance and extended tool life compared to standard HSS bits. The drill measures 0.0135 inches in diameter (wire size 80) with an overall length of 0.984 inches and a flute length of 2.40 mm. It features a 118-degree faceted point, web-thinned and tapered web construction for easier penetration, and a straight-cylindrical shank with a 1.00 mm shank diameter. This bit is sized and finished for use by machinists, tool-and-die makers, and precision fabricators working in production or repair environments.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is rated for primary use in aluminum (material codes K, M, N, P) and is also suitable for titanium alloy (material code S) as a secondary workpiece material. It follows DIN 1899 specification and belongs to GUHRING Series 660, a line engineered for small-diameter, high-precision drilling. Typical applications include printed circuit board work, instrument components, aerospace parts, and any task requiring a wire-gauge hole with close dimensional control. Maximum drilling depth is 0.074 inches (1.89 mm), making it appropriate for shallow, precise bores rather than deep-hole operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction with TiN coating for heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eWire size 80 diameter at 0.0135 inches with tight tolerance of +0.000 to -0.004 mm\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted point with web thinning for reduced entry force\u003c\/li\u003e\n  \u003cli\u003eTapered web and regular spiral flute for consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, straight-cylindrical shank compatible with standard micro chucks\u003c\/li\u003e\n  \u003cli\u003eDIN 1899 specification, Series 660, with 5xD flute-to-diameter ratio\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 1899-compliant micro drill bit for use in standard straight-shank micro chucks and collet holders accepting a 1.00 mm shank diameter.

Ensure the spindle and chuck are fully stopped and de-energized before inserting or removing the bit. Confirm chuck concentricity and proper seating of the straight shank before operation, as runout at this diameter will significantly affect hole quality and tool life. Do not exceed the maximum drilling depth of 0.074 inches per the manufacturer specification.\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: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0135 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: 0.074 inches (1.89 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: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (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\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\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.004 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\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: 660\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 1899\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 9006600003400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51754500194610,"sku":"9006600003400","price":39.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b8fdef352c0dab9d4347582ab44b9cde.jpg?v=1788946064","url":"https:\/\/voomisupply.com\/products\/guhring-9006600003400-micro-drill-bit-size-80-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
