Built to DIN 1899 standards, this wire gauge size 72 bit has a decimal diameter of 0.0252 inches and a 118-degree standard point angle. The M35 cobalt steel construction provides heat resistance and edge retention when drilling hard or abrasive workpieces. At 25 mm overall length with a 1 mm straight-cylindrical shank, it is suited for high-precision work in CNC machining centers, drill presses, and precision hand tools. A web-thinned, tapered web design reduces thrust and improves chip evacuation in small-diameter applications.\u003c\/p\u003e\u003cp\u003eThis micro drill bit is used in precision machining environments including aerospace, electronics, and industrial fabrication where tight tolerances are required. It supports blind hole drilling, through hole drilling, and stack drilling operations. The spiral flute geometry and right-hand cut are standard for use with conventional rotating spindles. The bright, uncoated finish makes it suitable for applications where coating interaction with the workpiece material is a concern, particularly with titanium alloys and composite materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWire gauge size 72 with 0.0252 inch decimal diameter and diameter tolerance of +0.000 to -0.004 mm\u003c\/li\u003e\n\u003cli\u003eM35 cobalt construction for heat and wear resistance in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003e118-degree standard point angle with web-thinned, tapered web for reduced thrust\u003c\/li\u003e\n\u003cli\u003eSpiral flute, right-hand cut geometry for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 1 mm shank fits standard collets and precision chucks\u003c\/li\u003e\n\u003cli\u003eRated for blind hole, through hole, and stack drilling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style micro drill bit conforming to DIN 1899 specifications, suitable for use with precision spindles and collet systems accepting a 1 mm straight-cylindrical shank.

Ensure the spindle and collet are free of debris and that runout is minimized before securing the shank, as small-diameter bits are sensitive to misalignment. Power down the machine and follow lockout\/tagout procedures before changing tooling. Do not exceed recommended feed and speed parameters for the workpiece material to avoid bit breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire)\u003c\/strong\u003e: 72\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.0252 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt (M35)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePoint Angle\u003c\/strong\u003e: 118 degrees\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: 4.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 3.10 mm (0.1000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eStandards\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\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: 5062898\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER-TITEX","offers":[{"title":"Default Title","offer_id":51731672990002,"sku":"5062898","price":141.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d404aa90efb4001bb66290e41e46960_e3e88314-139a-4ace-bde7-dee9a53a9b4a.jpg?v=1788733761","url":"https:\/\/voomisupply.com\/products\/walter-titex-5062898-cobalt-micro-drill-bit-size-72","provider":"Voomi Supply","version":"1.0","type":"link"}
