It measures 0.79 mm (0.0311 inches) in diameter with a 1.00 mm straight-cylindrical shank and an overall length of 25.00 mm. The 118-degree standard point angle and web-thinned, tapered web configuration promote accurate entry and reduce thrust in hard or abrasive workpieces. A spiral flute with a 5xD flute-to-diameter ratio provides chip evacuation in short, controlled drilling cycles. This bit is part of the Series A3143, manufactured to DIN 1899 standards, and is sized for work that requires tight tolerances and consistent hole geometry.\u003c\/p\u003e\n\u003cp\u003eThis micro drill bit is engineered for blind hole, through hole, and stack drilling applications. The primary workpiece material rating covers titanium alloy and similar high-strength alloys (material codes K, N, P, S). Secondary workpiece suitability includes glass and graphite (material codes M, O). Its cobalt construction gives it elevated heat resistance for use in materials that generate high cutting temperatures. Typical users include precision machinists, aerospace fabricators, and tool-and-die shops working with small-diameter hole requirements in difficult materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material for high heat resistance in titanium alloy and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for accurate positioning and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish maintains dimensional consistency without coating buildup at micro diameters\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.000 to -0.004 mm for tight, repeatable hole geometry\u003c\/li\u003e\n  \u003cli\u003eSpiral flute, right-hand cut with 5xD flute ratio for effective chip evacuation in short drill depths\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 as an OEM-specification micro drill bit per DIN 1899 for use in precision drilling operations on titanium alloy, glass, and graphite workpieces where small-diameter, controlled-depth holes are required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis micro drill bit is installed by machinists and precision tool operators using a compatible collet or chuck sized for a 1.00 mm shank diameter. Ensure the spindle and workpiece holding fixture are secure before operation, as micro drill bits are sensitive to runout and lateral loading. Maximum drilling depth is 4.10 mm; exceeding this depth risks flute clogging and bit breakage. Coolant through is not supported on this bit, so external lubrication or dry cutting per material recommendations should be followed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.79 mm (0.0311 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: 5.30 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 4.10 mm (0.2000 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\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: 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\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\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 (K, N, P, S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Glass, Graphite (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\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: 5062913\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51736842797362,"sku":"5062913","price":141.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d404aa90efb4001bb66290e41e46960_0cb92815-2217-4dcf-879e-d2a67d2e597d.jpg?v=1788780972","url":"https:\/\/voomisupply.com\/products\/walter-titex-5062913-micro-drill-bit-0-79-mm-cobalt-118-point","provider":"Voomi Supply","version":"1.0","type":"link"}
