Built from high speed steel with a bright, uncoated finish, this Series 552 bit features a parabolic flute geometry and a web-thinned, parallel web configuration that improves chip evacuation and reduces thrust in short-hole applications. The 130-degree point angle suits aluminum and a range of non-ferrous materials. At 2-1\/16 inches overall length with a 25\/32-inch flute, this bit fits standard drill chucks and CNC toolholders with a straight cylindrical shank. It is a right-hand cut tool conforming to DIN 1897.\u003c\/p\u003e\u003cp\u003eThis drill bit is sized at 0.136 inches in diameter, equivalent to wire gauge #29, and is classified as a stub or screw machine length drill. That shorter body length increases rigidity and reduces deflection during high-speed, shallow-hole drilling operations. It is well suited for drilling aluminum, soft metals, and similar workpiece materials on drill presses, CNC machining centers, and screw machines. The maximum drilling depth is 0.584 inches. The 3xD flute-to-diameter ratio supports controlled chip clearance without excessive flute length. Installation and use is appropriate for machinists, toolroom techs, and CNC operators.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eParabolic flute design with web thinning for improved chip evacuation and reduced thrust\u003c\/li\u003e\n\u003cli\u003e130-degree point angle optimized for aluminum and non-ferrous workpiece materials\u003c\/li\u003e\n\u003cli\u003eStub length body increases rigidity and minimizes deflection in shallow-hole applications\u003c\/li\u003e\n\u003cli\u003eBright, uncoated high speed steel construction rated for high-performance grade use\u003c\/li\u003e\n\u003cli\u003eRight-hand cut with straight cylindrical shank for standard chuck and collet compatibility\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 1897 specification for stub-length twist drills\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style screw machine length drill bit for use in standard drill chucks, CNC toolholders, and collet systems accepting a straight cylindrical shank at 0.136 inches diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by qualified machinists or CNC operators familiar with cutting tool setup. Ensure the spindle and machine are fully de-energized and at rest before changing tooling. Secure the shank fully within the chuck or collet before operation, and verify runout with a dial indicator when precision is required. Consult machine manufacturer feed and speed recommendations for the specific workpiece material — do not exceed the rated maximum drilling depth of 0.584 inches for this bit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.136 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Wire Gauge)\u003c\/strong\u003e: #29\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 25\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.584 inches\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\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\u003ePoint Type\u003c\/strong\u003e: Standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum\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\u003eDrill Bit Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.018 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 552\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Grade\u003c\/strong\u003e: High Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 9005520034500\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51747289497906,"sku":"9005520034500","price":18.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c004b3b6061efa47988640bd972ac410.jpg?v=1788878689","url":"https:\/\/voomisupply.com\/products\/guhring-9005520034500-screw-machine-drill-bit-0-136-in","provider":"Voomi Supply","version":"1.0","type":"link"}
