It carries a 0.0295-inch diameter with a 118-degree faceted point and web-thinned geometry that reduces entry force and improves centering on hard-to-start surfaces. The overall length is 0.984 inches, and the spiral flute configuration promotes chip evacuation in short, shallow holes. Built to DIN 1899 specification, this bit suits production environments where tight tolerances and consistent hole quality are required. It is sold individually but must be ordered in multiples of 10.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for use in aluminum as its primary workpiece material and titanium alloy as a secondary application, corresponding to material codes K, M, N, P, and S. The straight-cylindrical shank with a 1.00 mm shank diameter fits standard micro-drill chucks and collet holders. Maximum drilling depth is 0.145 inches (3.68 mm), making it appropriate for through-holes and shallow blind holes in thin stock, circuit board substrates, and precision mechanical components. The right-hand cut and regular spiral type are standard for conventional CNC and benchtop drill press setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction provides heat resistance for drilling aluminum and titanium alloy\u003c\/li\u003e\n  \u003cli\u003e118-degree faceted point with web thinning improves self-centering and reduces thrust force\u003c\/li\u003e\n  \u003cli\u003eDIN 1899 specification ensures dimensional consistency across production lots\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish maintains sharp edge geometry without coating buildup at micro scale\u003c\/li\u003e\n  \u003cli\u003eTapered web configuration with 5xD flute-to-diameter ratio supports chip flow in shallow holes\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.000 to -0.004 mm supports close-tolerance hole requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use micro drill bit for applications conforming to DIN 1899 Series 301 standards, with a 1.00 mm straight-cylindrical shank compatible with standard micro-drill collets and chucks.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this micro drill bit should be performed by machinists or tooling technicians familiar with high-speed micro-drilling operations. Ensure the drill press or CNC spindle is fully stopped and secured before loading or removing the bit from the collet or chuck. At 0.0295-inch diameter, the bit is highly susceptible to breakage from side loading, runout, or excessive feed rate — use a rigid setup and verified spindle runout within tolerance before drilling. Coolant-through is not supported on this tool; apply external coolant or cutting fluid as appropriate for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.0295 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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.145 inches (3.68 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\u003eFlute Length\u003c\/strong\u003e: 4.80 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\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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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 (K, M, N, P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Titanium Alloy (S)\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\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: 9003010007500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51731645661490,"sku":"9003010007500","price":172.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9089d180265fa55554780b383a17dc24.jpg?v=1788733510","url":"https:\/\/voomisupply.com\/products\/guhring-9003010007500-micro-drill-bit-0-0295-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
