Built from high speed steel with a bright, uncoated finish, this bit features a parabolic flute geometry and a web-thinned, parallel web configuration that promotes efficient chip evacuation and reduced thrust at the cutting edge. The 130-degree drill point angle suits shallow entry and exit in softer metals. With an overall length of 4.2126 inches and a cutting diameter of 14.00 mm (0.5512 inches), this bit is sized for production and maintenance drilling where a shorter, stiffer stub-length tool reduces deflection and improves hole accuracy. Licensed machinists, tool-and-die professionals, and CNC setup technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for stub-length drilling applications in aluminum, soft alloys, and similar workpiece materials where chip evacuation is a concern. The parabolic flute design increases chip curl and helps move material out of the hole faster than standard helix flutes, making it a practical choice for deeper holes relative to diameter in soft metals. The Series 552 designation and DIN 1897 standard confirm its geometry is matched to established screw machine length specifications used in both manual and CNC drilling operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e14.00 mm (0.5512 inch) cutting diameter with a tolerance of +0.000 to -0.027 mm for consistent hole sizing\u003c\/li\u003e\n\u003cli\u003e130-degree standard point angle optimized for aluminum and non-ferrous entry\u003c\/li\u003e\n\u003cli\u003eParabolic flute geometry with web thinning improves chip flow and reduces cutting force\u003c\/li\u003e\n\u003cli\u003eStub (screw machine) length body at 4.2126 inches overall reduces deflection in short-reach setups\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders without modification\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 1897 specification for dimensional consistency across replacements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a DIN 1897 stub-length replacement drill bit suitable for use in CNC machining centers, drill presses, and screw machines accepting a straight-cylindrical shank in the 0.5512 inch diameter range.

A properly sized drill chuck or collet holder should be used to secure the straight-cylindrical shank without runout. Machinists should verify spindle speed and feed rate against the workpiece material before engaging the cut. Inspect the cutting edge and web for wear or chipping before each use to maintain hole tolerance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 14.00 mm \/ 0.5512 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 107.00 mm \/ 4.2126 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 54.00 mm \/ 2.1260 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 33.00 mm \/ 1.2990 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.027 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: 9005520140000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51754462118194,"sku":"9005520140000","price":87.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f43b2854de70a08591ee7c9e894ec46d.jpg?v=1788945661","url":"https:\/\/voomisupply.com\/products\/guhring-9005520140000-stub-drill-bit-0-5512-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
