Built to DIN 1899 standards, this wire gauge size 84 bit measures 0.0114 inches (0.29 mm) in diameter and delivers a 118-degree standard point angle for accurate entry and reduced walking. The M35 cobalt steel construction provides heat resistance and edge retention well beyond standard high-speed steel, making it the right choice when drilling titanium alloys, glass, and graphite where tool life and dimensional accuracy are critical. The spiral flute geometry and web-thinned, tapered web configuration aid chip evacuation in tight, shallow holes.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for precision micro-drilling applications in aerospace, tooling, and specialty fabrication environments. Typical use cases include blind hole drilling, stack drilling, and through-hole drilling in titanium alloys as the primary workpiece material, with secondary capability in glass and graphite. The straight-cylindrical shank seats cleanly in standard collet chucks and precision drill presses. The 25 mm overall length and 1.90 mm flute length are sized for shallow-depth micro work where rigidity and runout control are paramount.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eWire size 84 (0.0114 inches decimal) for micro-precision hole making\u003c\/li\u003e\n  \u003cli\u003eM35 cobalt construction resists heat buildup when drilling titanium alloy and hard non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point with web-thinned, tapered web for clean entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eSpiral flute design promotes chip evacuation in blind and through-hole applications\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish; diameter tolerance held to +0.000 to -0.004 mm for consistent fit\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 1899 specification for dimensional consistency across the series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 1899 Series A3143 micro drill bit for use in blind hole, stack drilling, and through-hole drilling operations.

Secure the straight-cylindrical shank in a precision collet or drill chuck rated for the shank diameter before use. Ensure the spindle and workpiece are properly fixtured to minimize runout, which is especially critical at this diameter. Do not exceed recommended feed and speed parameters for the workpiece material, as micro-diameter cobalt drills are susceptible to breakage under side load or excessive feed force.\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\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M35)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 25.00 mm (approximately 0.984 inches)\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: 1.40 mm (0.1000 inches)\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 Type\u003c\/strong\u003e: Spiral (Regular)\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\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: 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\u003eStandard\u003c\/strong\u003e: DIN 1899\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A3143\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: WALTER-TITEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5062863\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51732988789042,"sku":"5062863","price":177.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d404aa90efb4001bb66290e41e46960_4e661eb1-bbe5-4265-a801-245c0ac21491.jpg?v=1788750085","url":"https:\/\/voomisupply.com\/products\/walter-titex-5062863-micro-drill-bit-wire-84-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
