Built to DIN 1899 standards, this bit features a 0.3 mm diameter with a 118-degree standard point angle and a web-thinned, tapered web configuration that reduces entry force and improves centering accuracy. The M35 cobalt grade construction provides heat and wear resistance needed when cutting titanium alloys and other hard materials. With an overall length of 25 mm and a 1 mm straight-cylindrical shank, it is suited for use in precision CNC machining centers, micro-drilling fixtures, and high-speed drill presses operated by machining professionals and tool-and-die technicians.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is intended for blind hole, through hole, and stack drilling applications in titanium alloys as its primary workpiece material. Secondary workpiece materials include glass and graphite. The Series A3143 designation identifies it within the WALTER-TITEX micro drill product line. Its 5xD flute-by-diameter ratio and 1.90 mm flute length accommodate the shallow depths typical of micro-hole operations, with a maximum drilling depth of 1.40 mm. It is sold individually with a minimum order quantity of 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM35 cobalt construction for elevated heat resistance when drilling titanium alloys\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for accurate entry\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish; no coating buildup that could affect tolerance at micro diameters\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to +0.000 to -0.004 mm for consistent hole sizing\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute geometry promotes chip evacuation in blind and through holes\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 1899 specification for standardized micro drill geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in precision drilling of titanium alloys, glass, and graphite.

Ensure the machine spindle and collet are clean and properly seated before securing the 1 mm shank to prevent runout at this diameter. Power down and lock out the machine before changing tooling. Avoid applying side loads or using this bit in hand-held drill applications, as micro-diameter bits are highly susceptible to breakage under lateral force.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3 mm (0.0118 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 25 mm\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 (0.100 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\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\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\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\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  \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: 5062864\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51751341261106,"sku":"5062864","price":178.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d404aa90efb4001bb66290e41e46960_adefa57a-2b5f-4c1c-89f2-87f8b26796ef.jpg?v=1788922940","url":"https:\/\/voomisupply.com\/products\/walter-titex-5062864-micro-drill-bit-0-3-mm-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
