Built to DIN 1899 standards, this wire gauge size 69 bit measures 0.0292 inches in diameter with an overall length of 25 mm and a flute length of 4.80 mm. The 118-degree standard point angle and web-thinned, tapered web configuration allow for accurate entry and reduced thrust in tight-tolerance applications. The bright, uncoated cobalt construction provides heat resistance and edge retention when working in hard or abrasive workpiece materials. Right-hand spiral fluting promotes efficient chip evacuation during through-hole and blind-hole drilling operations. This bit is intended for use by machinists and precision fabricators working in production or toolroom environments.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is well suited for blind hole drilling, stack drilling, and through-hole drilling in titanium alloy as its primary workpiece material. Secondary applications include drilling in glass and graphite. The straight-cylindrical shank with a 1.00 mm diameter fits standard micro drill chucks and collet holders. At a 5xD flute-to-diameter ratio and a maximum drilling depth of 3.60 mm (0.1000 inch), this bit is optimized for shallow, precise holes where dimensional accuracy is critical. It is a practical choice for aerospace component work, electronics, and specialty fabrication requiring consistent micro-diameter results.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for improved heat resistance and durability in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for accurate entry and reduced walking\u003c\/li\u003e\n  \u003cli\u003eWire gauge size 69 (0.0292 inches) diameter with a tight tolerance of +0.000 to -0.004 mm\u003c\/li\u003e\n  \u003cli\u003eSpiral flute, right-hand cut for efficient chip evacuation during micro-hole operations\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 1.00 mm diameter for compatibility with standard micro drill chucks\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 1899 specification for consistent dimensional standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification micro drill bit per DIN 1899 Series A3143, suited for use with standard straight-cylindrical micro drill chucks and collet systems accepting a 1.00 mm shank diameter.

Secure the bit firmly in a calibrated micro drill chuck or collet before operation to prevent runout. Because of the extremely small diameter, avoid side loading or flexing forces that can cause bit breakage. Inspect the cutting edge and point condition before each use, as cobalt micro bits are sensitive to chipping at this diameter range.\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: 69\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0292 inches\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: 25.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.80 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.60 mm (0.1000 inch)\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: Bright\/Uncoated\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, 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\u003eCoolant Through\u003c\/strong\u003e: No\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: Titanium Alloy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Glass, Graphite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Blind Hole, Stack Drilling, Through Hole Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A3143\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\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: WALTER-TITEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5062908\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51731493912882,"sku":"5062908","price":140.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d404aa90efb4001bb66290e41e46960_c50de6b7-3472-446f-bd05-517d649851da.jpg?v=1788731738","url":"https:\/\/voomisupply.com\/products\/walter-titex-5062908-micro-drill-bit-size-69-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
