Built to DIN 1899 standards, this wire-size #70 bit has a decimal inch diameter of 0.0280 inches and an overall length of 25 mm. The 118-degree standard point with web thinning and a tapered web configuration promotes accurate entry and reduces thrust force in tough substrates. The spiral flute geometry and right-hand cut make this bit suitable for blind hole, through hole, and stack drilling applications. It is intended for use by machinists and tooling professionals working in precision manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is suited for small-diameter drilling operations in tight-tolerance work, particularly when machining titanium alloys or non-metallic materials such as glass and graphite. The straight-cylindrical shank fits standard collet chucks and drill presses used in precision machine shops. With a flute length of 4.80 mm and a maximum drilling depth of 3.60 mm, it is optimized for shallow, controlled penetration typical of micro-hole applications. The Series A3143 designation places it within a cobalt tooling line engineered for rigidity and wear resistance at small diameters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt construction provides wear resistance and heat tolerance in hard or abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eWire size #70 with 0.0280-inch decimal diameter for tight-tolerance micro drilling\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web thinning for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eSpiral flute with right-hand cut supports chip evacuation in blind and through hole drilling\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard collet and drill chuck tooling\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 1899 specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and precision hand-held drilling equipment accepting a 1.00 mm straight-cylindrical shank.

Secure the shank fully in the collet or chuck before operation and verify runout is within tolerance to prevent bit deflection or breakage at this diameter. Always power down and lock out spindle rotation before changing tooling. Diameter tolerance for this bit is plus 0.000 to minus 0.004 mm, so verify fitment with gauge pins when tight tolerances are required.\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: #70\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0280 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 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\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\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, Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eCoolant Through\u003c\/strong\u003e: No\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\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\u003eDiameter Tolerance\u003c\/strong\u003e: plus 0.000 to minus 0.004 mm\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: 5062905\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51728497017138,"sku":"5062905","price":132.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d404aa90efb4001bb66290e41e46960_93b4c007-e760-48e8-827b-c1d24b88e20e.jpg?v=1788692166","url":"https:\/\/voomisupply.com\/products\/walter-titex-5062905-micro-drill-bit-wire-70-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
