Built to M35 material grade cobalt, it delivers heat resistance and edge retention well beyond standard high-speed steel tooling. The bit carries a wire gauge size of 82, corresponding to a decimal diameter of 0.0126 inches, with a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces thrust load at entry. Overall length is 25 mm with a 1.00 mm straight-cylindrical shank. This tool is intended for use by machinists and CNC operators working in production or job-shop environments where tight tolerances and small-diameter drilling are routine.\u003c\/p\u003e\n\u003cp\u003eThe 5062866 is rated for blind hole, through hole, and stack drilling applications. Its primary workpiece material is titanium alloy, with secondary suitability for glass and graphite. The spiral flute geometry with a 5xD flute-to-diameter ratio clears chips efficiently in shallow cuts, with a maximum drilling depth of 1.80 mm. The bright, uncoated finish makes tool wear easy to inspect between runs. This bit conforms to DIN 1899 specification, making it a standard-compliant choice for metric tooling programs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM35 cobalt construction for elevated heat and wear resistance in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eWire size 82 diameter, 0.0126 inches, with tight tolerance of +0.000 to -0.004 mm\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute, 5xD ratio, supports blind hole, through hole, and stack drilling\u003c\/li\u003e\n  \u003cli\u003e1.00 mm straight-cylindrical shank for compatibility with standard collets and chucks\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 1899; bright, uncoated finish for easy visual inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for precision drilling setups requiring DIN 1899 compliant micro drill bits in wire size 82 with a straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of this tool should be performed by qualified machinists familiar with micro-diameter drilling procedures. Secure the shank fully in a collet or drill chuck rated for 1.00 mm shanks before operation, and verify runout with a dial indicator when tolerances are critical. Power down the machine and confirm zero spindle speed before bit changes. Avoid side loading or peck drilling depths beyond the rated 1.80 mm maximum to prevent bit deflection or breakage.\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: 82\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter (Decimal Inch)\u003c\/strong\u003e: 0.0126 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: 2.40 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.80 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\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\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\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\u003eTool Material\u003c\/strong\u003e: Cobalt, M35 Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 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: 5062866\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51728008642866,"sku":"5062866","price":170.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d404aa90efb4001bb66290e41e46960_68b53407-41ea-4fda-8ad2-7147bb995c75.jpg?v=1788686048","url":"https:\/\/voomisupply.com\/products\/walter-titex-5062866-micro-drill-bit-wire-82-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
