Built to DIN 1899 standards, it features a 0.86 mm diameter, a 118-degree standard point angle, and a web-thinned, tapered web configuration that reduces thrust and improves centering at entry. The straight-cylindrical shank measures 1.50 mm in diameter, and the overall length is 25.00 mm. The bright\/uncoated cobalt construction provides good heat resistance without a coating layer, making it well suited for short-run precision work where regrinding or close inspection of the cutting edge is routine.\u003c\/p\u003e\n\u003cp\u003eThis bit is sized for micro-drilling applications found in aerospace component machining, electronics fabrication, and precision metalworking shops. It supports blind hole, stack drilling, and through hole drilling operations. The spiral flute with a 5xD flute-by-diameter ratio and a maximum drilling depth of 4.50 mm makes it appropriate for shallow, tight-tolerance holes in thin-section titanium alloy workpieces. Secondary workpiece materials include glass and graphite, extending its usefulness to composite and specialty substrate applications. A right-hand cut direction is standard. This bit is sold individually but carries a minimum order quantity of 10 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCobalt tool material provides elevated heat resistance for hard and abrasive workpiece materials\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n  \u003cli\u003eDIN 1899 compliant construction for consistent dimensional standards\u003c\/li\u003e\n  \u003cli\u003eSupports blind hole, stack drilling, and through hole drilling operations\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.000 to -0.004 mm for tight-tolerance work\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard micro-drill chuck systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003ePrimary workpiece materials are titanium alloy and materials coded K, N, P, and S per the input specification.

Always confirm the machine spindle and chuck are fully powered down and locked out before changing tooling. Verify chuck collet or drill chuck clearance is appropriate for a 1.50 mm shank before tightening. At 0.86 mm diameter, excessive side load or misalignment will cause bit breakage; confirm workpiece fixturing and spindle runout are within tolerance before drilling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.86 mm (0.0339 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: 6.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 4.50 mm (0.2000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.50 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\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, 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\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\u003eCoolant Through\u003c\/strong\u003e: No\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: 5062920\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51753731916082,"sku":"5062920","price":143.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d404aa90efb4001bb66290e41e46960_1ab36c7e-59a0-474c-b335-b59d57ebffeb.jpg?v=1788940090","url":"https:\/\/voomisupply.com\/products\/walter-titex-5062920-micro-drill-bit-0-86-mm-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
