Built to DIN 1897 standards, this bit measures 0.055 inches (1.40 mm) in diameter with a 130-degree point angle and a parabolic flute geometry. The web-thinned, parallel-web construction reduces thrust force at entry, making it well suited for precision drilling in production environments. With an overall length of 1.26 inches and a flute length of 0.354 inches, this compact stub-length bit offers increased rigidity compared to standard jobber-length drills.\u003c\/p\u003e\u003cp\u003eThis drill bit is primarily intended for drilling aluminum and other non-ferrous materials in screw machine and CNC drilling operations. The parabolic flute profile promotes efficient chip evacuation, which is critical when running at higher spindle speeds in automated or production setups. The straight cylindrical shank fits standard drill chucks without modification. Maximum drilling depth is 0.272 inches, making it appropriate for shallow-hole applications common in precision machining and parts manufacturing. It ships individually but carries a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDIN 1897 stub-length standard for added rigidity and reduced deflection\u003c\/li\u003e\n\u003cli\u003e130-degree point angle with web thinning for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eParabolic flute design promotes fast chip evacuation at higher feed rates\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated HSS finish suitable for aluminum and non-ferrous workpieces\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with straight cylindrical shank for universal chuck compatibility\u003c\/li\u003e\n\u003cli\u003eDiameter tolerance of +0.000 to -0.014 mm for consistent hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style stub drill bit conforming to DIN 1897 specifications, compatible with standard drill chucks accepting straight cylindrical shanks in the 0.055-inch diameter range.

Ensure the drill chuck is properly tightened and the workpiece is securely fixtured before initiating any drilling cycle. Inspect the bit for chipping or wear before each use, particularly at the cutting edge and web. Do not exceed the maximum drilling depth of 0.272 inches per pass without retracting to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.055 inches (1.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Size\u003c\/strong\u003e: #54\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.26 inches (32.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 0.354 inches (9.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.272 inches (6.90 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: Parabolic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\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\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\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: 9005520014000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51729623318834,"sku":"9005520014000","price":88.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4376398ddd0576d1846edfac275e2736.jpg?v=1788706875","url":"https:\/\/voomisupply.com\/products\/guhring-9005520014000-stub-drill-bit-0-055-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
