It carries a 0.1280-inch (3.25 mm) diameter with a 130-degree split point and a parabolic flute geometry that promotes efficient chip evacuation and reduced cutting force. The overall length is 4.172 inches (106 mm) with a flute length of 2.719 inches (69 mm). Manufactured from high-speed steel with a bright\/uncoated finish, this bit is intended for use by machinists, tool-and-die professionals, and industrial maintenance technicians who require consistent dimensional accuracy in production drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for right-hand drilling in aluminum alloy, cast iron, and steel. The taper length format provides additional reach compared to a jobber-length bit, making it practical for deeper-hole applications in structural components and machined parts. It conforms to DIN 340 specification, which defines taper length drill geometry. The cylindrical shank fits standard drill chucks and collet holders. A maximum drilling depth of 2.525 inches (64.13 mm) makes it appropriate for through-hole and deep-hole work within its rated capacity.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eParabolic flute design promotes fast chip removal and lowers heat buildup during extended drilling cycles\u003c\/li\u003e\n  \u003cli\u003e130-degree point angle with web-thinned tip reduces thrust force and improves self-centering on entry\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides toughness across aluminum alloy, cast iron, and steel workpieces\u003c\/li\u003e\n  \u003cli\u003eDIN 340 taper length configuration extends reach beyond standard jobber drills without sacrificing rigidity\u003c\/li\u003e\n  \u003cli\u003eCylindrical shank with 0.1280-inch diameter fits directly into standard drill chucks and collet systems\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suits general-purpose metal drilling where coating adhesion is not a requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in aluminum alloy, cast iron, and steel.

Ensure the spindle and workpiece are fully secured before engaging the cutting edge. Power down and de-energize all equipment before bit changes or chuck adjustments. Do not exceed the rated maximum drilling depth of 2.525 inches in a single pass without withdrawing to clear chips.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.1280 inches (3.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.172 inches (106 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.719 inches (69 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.525 inches (64.13 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1280 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.457 inches (37 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\u003eFlute Type\u003c\/strong\u003e: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length to Diameter Ratio\u003c\/strong\u003e: 10xD\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: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum Alloy, Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.018 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Number\u003c\/strong\u003e: DIN 340\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 535\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.011 pounds\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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9005350032500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51735022928178,"sku":"9005350032500","price":40.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3be36b21e23759d42cf370e596f964a.jpg?v=1788769316","url":"https:\/\/voomisupply.com\/products\/guhring-9005350032500-taper-length-drill-bit-0-1280-in","provider":"Voomi Supply","version":"1.0","type":"link"}
