Built to DIN 1899 standards, it features a 0.45 mm diameter, a 118-degree standard point, and a web-thinned, tapered web design that reduces entry force and improves centering accuracy. The M35 cobalt steel construction resists heat buildup during high-speed drilling in tough alloys. With an overall length of 25.00 mm and a 1.00 mm straight-cylindrical shank, this bit fits standard micro-drill chucks and collets. It is sold individually and suited for precision machining shops, aerospace fabricators, and skilled trade professionals working at tight tolerances.\u003c\/p\u003e\u003cp\u003eThis micro drill bit is designed for blind hole, through-hole, and stack drilling operations. Its primary workpiece material rating covers titanium alloys and a range of ferrous and non-ferrous metals. It also handles secondary materials including glass and graphite where micro-drilling is required. The 5xD flute-to-diameter ratio and 3.00 mm flute length support chip evacuation in shallow, precise holes with a maximum drilling depth of 2.20 mm. The bright, uncoated finish maintains dimensional accuracy without added coating thickness, which matters at sub-millimeter diameters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.45 mm diameter with a tight tolerance of +0.000 to -0.004 mm for precise hole sizing\u003c\/li\u003e\n\u003cli\u003eM35 cobalt steel construction for heat resistance in titanium alloys and hard metals\u003c\/li\u003e\n\u003cli\u003e118-degree standard point with web-thinning for reduced thrust and accurate starts\u003c\/li\u003e\n\u003cli\u003eSpiral flute, right-hand cut for standard CNC and bench-drill applications\u003c\/li\u003e\n\u003cli\u003eDIN 1899 compliant construction for consistent dimensional quality\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 1.00 mm shank fits standard micro-drill chucks and collets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Series A3143 micro-drilling applications. Rated for primary workpiece materials including titanium alloy and related material codes K, N, P, and S. Secondary material compatibility includes glass and graphite (codes M and O). Confirm spindle speed and feed rate recommendations for the specific workpiece material before use.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis bit is installed by qualified machinists or precision drilling technicians using appropriate micro-drill chucks or collets rated for 1.00 mm shanks. Ensure the spindle and workpiece fixture are fully secured before operation. At sub-millimeter diameters, runout in the chuck or collet can cause premature breakage; verify chuck concentricity before use. Follow the machine manufacturer's recommended spindle speed and feed rates for cobalt tooling in the target material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.45 mm (0.0177 inches)\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: 3.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.20 mm (0.1000 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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium Alloy (Material Codes K, N, P, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Glass, Graphite (Material Codes M, O)\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\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003eSeries\u003c\/strong\u003e: A3143\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1899\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5062879\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51730872074546,"sku":"5062879","price":153.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d404aa90efb4001bb66290e41e46960_841cf414-7745-423e-9042-9d557d3adbf1.jpg?v=1788724176","url":"https:\/\/voomisupply.com\/products\/walter-titex-5062879-micro-drill-bit-0-45-mm-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
