Built to DIN 1897 standards, this Series 329 bit measures 0.1043 inches (2.65 mm) in diameter with an overall length of 1.6929 inches (43 mm). The M35 cobalt steel construction and oxide tip coating provide heat resistance and extended tool life when cutting through tough workpiece materials such as titanium alloy. The 130-degree point angle and web-thinned, tapered web geometry improve centering and reduce thrust force during entry. Licensed HVAC techs, machinists, and metal fabricators working with close-tolerance bores rely on bits like this for consistent, repeatable results.\u003c\/p\u003e\u003cp\u003eThis stub-length drill bit is suited for applications where a shorter flute length improves rigidity and reduces deflection. The 0.5512-inch (14 mm) flute length and 3xD flute-to-diameter ratio make it well-matched for shallow-depth holes in production and job-shop environments. Primary recommended workpiece material is titanium alloy, though the cobalt M35 grade is broadly used on stainless steels and other high-hardness alloys. Right-hand cut with a straight-cylindrical shank for direct chuck mounting.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM35 cobalt tool steel with oxide tip coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003e130-degree drill point angle with web-thinned, tapered web for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eDIN 1897 stub length for improved rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks directly\u003c\/li\u003e\n\u003cli\u003e2-flute regular spiral design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.000 to -0.014 mm for close-tolerance bore work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a stub-length replacement or production drill for applications requiring a 2.65 mm (0.1043 inch) diameter hole in titanium alloy and other high-hardness metals, conforming to DIN 1897 specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstall in a standard drill press, CNC machining center, or hand drill with a compatible chuck sized for a 2.65 mm straight-cylindrical shank. Ensure the workpiece is securely fixtured before drilling. Use appropriate cutting fluid or coolant for titanium alloy and similar materials to manage heat buildup. Inspect the cutting edge before each use and replace bits that show chipping or wear to maintain hole-diameter accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1043 inches (2.65 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.6929 inches (43 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.5512 inches (14 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.1417 inches (29 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 2.65 mm straight-cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.5512 inches (14 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt M35\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide (tip)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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, Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Titanium Alloy\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 -0.014 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 329\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.104 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9003290026500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51747582148914,"sku":"9003290026500","price":115.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13d9679f7fd4066600f9deffc85dd218.jpg?v=1788882873","url":"https:\/\/voomisupply.com\/products\/guhring-9003290026500-stub-drill-bit-0-1043-in-cobalt","provider":"Voomi Supply","version":"1.0","type":"link"}
