Built to DIN 1899 standards, this bit features a 0.54 mm diameter, a 118-degree standard point angle, and a web-thinned, tapered web configuration that reduces thrust and improves centering on entry. The M35 cobalt steel construction provides heat resistance and edge retention when cutting titanium alloys and other abrasive workpiece materials. The bright uncoated finish is suited for applications where coating buildup or contamination is a concern. With a 25 mm overall length and a 1.00 mm straight-cylindrical shank, the bit seats securely in standard micro drill chucks and precision collets.\u003c\/p\u003e\n\u003cp\u003eThis bit is designed for blind hole, through hole, and stack drilling operations in tight-tolerance applications. The Series A3143 geometry with a 5xD flute-to-diameter ratio and spiral flute design promotes chip evacuation in shallow micro holes. Primary workpiece materials include titanium alloy, with secondary suitability for glass and graphite. The 3.90 mm flute length and 3.00 mm maximum drilling depth make this bit appropriate for thin-section and laminate work where breakout control and hole quality are critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM35 cobalt construction for heat resistance and durability in titanium alloy cutting\u003c\/li\u003e\n  \u003cli\u003e118-degree standard point angle with web-thinned, tapered web for accurate entry and reduced thrust\u003c\/li\u003e\n  \u003cli\u003eSpiral flute design promotes chip evacuation in blind and through hole applications\u003c\/li\u003e\n  \u003cli\u003e1.00 mm straight-cylindrical shank fits standard micro drill chucks and precision collets\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish compatible with dry cutting and coolant-free operations\u003c\/li\u003e\n  \u003cli\u003eManufactured to DIN 1899 specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in blind hole, stack drilling, and through hole drilling operations.

Ensure the spindle and chuck are clean and true before seating the bit, as runout at this diameter will cause premature breakage. Confirm drilling depth does not exceed the 3.00 mm maximum to avoid bit deflection or fracture. Power down and de-energize all equipment before changing tooling.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.54 mm (0.0213 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: 3.90 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.00 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\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\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.004 mm\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\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\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: 5062888\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51747601908018,"sku":"5062888","price":142.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d404aa90efb4001bb66290e41e46960_caedd3dc-45f9-46e4-9228-5f307431f9ef.jpg?v=1788883242","url":"https:\/\/voomisupply.com\/products\/walter-titex-5062888-micro-drill-bit-0-54mm-cobalt-a3143","provider":"Voomi Supply","version":"1.0","type":"link"}
