Built to DIN 1897 standards from high speed steel with a bright\/uncoated finish, it features a parabolic flute geometry and a web-thinned, parallel-web configuration that improves chip evacuation and reduces thrust. The 130-degree point angle and standard point type make it well-suited for entry into aluminum and other non-ferrous materials. The straight-cylindrical shank seats securely in standard drill chucks and collets. This is a right-hand cut tool with a 3xD flute-to-diameter ratio, sized at 0.3772 inches (Letter V) in diameter.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in screw machine operations, CNC machining centers, drill presses, and hand-held power tools where a short, rigid stub-length drill is required. Its parabolic flute design supports faster feed rates and cleaner chip removal, making it a practical choice for repetitive through-hole and shallow-depth drilling in aluminum and similar workpiece materials. The 0.3772-inch diameter corresponds to Letter V drill sizing. Maximum drilling depth is 1.127 inches. Machinists, tool-and-die makers, and production floor technicians working in metalworking shops are the primary users of this bit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDIN 1897 stub length for increased rigidity and reduced deflection in short-reach applications\u003c\/li\u003e\n  \u003cli\u003eParabolic flute geometry with web thinning for improved chip flow and reduced cutting thrust\u003c\/li\u003e\n  \u003cli\u003e130-degree split point angle optimized for aluminum and non-ferrous workpiece materials\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction with bright\/uncoated finish suitable for standard cutting speeds\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with standard drill chucks and ER collet systems\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance of +0.000 to -0.022 mm for consistent, repeatable hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 1897-compliant stub-length drill bit for use with standard drill chucks, collets, and CNC toolholders accepting straight-cylindrical shanks in the 0.3500 to 0.4000 inch diameter range.

Ensure the machine spindle is fully stopped and the tool is properly seated and tightened in the chuck or collet before operation. Inspect the cutting edges for wear or damage before each use and replace when dimensional tolerance or surface finish degrades. Follow the machine manufacturer and tooling supplier guidelines for appropriate speeds and feeds for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3772 inches (Letter V)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 130 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.6875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.127 inches\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: Parabolic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.022 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub (Screw Machine Length)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 552\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\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: 9005520095800\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51747550691634,"sku":"9005520095800","price":49.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d91b06a1cb1096467b7bed1e6293e19.jpg?v=1788882391","url":"https:\/\/voomisupply.com\/products\/guhring-9005520095800-stub-drill-bit-0-3772-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
