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 force. The 130-degree point angle suits flat-entry cuts where a self-centering profile is needed. At 3.1102 inches overall length with a 1.4567-inch flute length, the stub format provides increased rigidity over jobber-length bits, making it a reliable choice for production drilling environments where precision and repeatability matter.\u003c\/p\u003e\u003cp\u003eThis drill bit suits short-hole and spot-drilling applications in machining, fabrication, and maintenance settings. The straight-cylindrical shank allows direct installation into standard drill chucks, collet holders, and CNC tool holders. Its 3xD flute-to-diameter ratio and maximum drilling depth of 1.008 inches make it well matched to screw machine operations, gang drilling fixtures, and light-duty CNC drilling cycles. The DIN 1897 specification confirms dimensional conformance to European industry standards, making it a dependable option for shops that source to recognized tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eParabolic flute geometry with web thinning for improved chip flow and reduced cutting resistance\u003c\/li\u003e\n\u003cli\u003e130-degree point angle optimized for aluminum and non-ferrous workpiece materials\u003c\/li\u003e\n\u003cli\u003eStub length format increases rigidity and minimizes deflection in short-hole applications\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with cutting fluids on non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank compatible with standard chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 1897 specification for consistent dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-specification stub drill bit conforming to DIN 1897, compatible with standard straight-shank drill chucks, ER collet holders, and screw machine spindles that accept a 0.2992-inch diameter shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use should be performed by a qualified machinist or tooling technician familiar with cutting tool handling. Secure the shank fully within the chuck or collet to the recommended grip depth before applying power. Inspect the cutting edges for chips or wear before each use, and ensure the workpiece is rigidly fixtured to prevent movement during drilling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2992 inches (7.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.1102 inches (79.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 1.4567 inches (37.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.008 inches (25.60 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\u003eFlute-to-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\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\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\u003eDrill Length Type\u003c\/strong\u003e: Stub\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 Diameter Tolerance\u003c\/strong\u003e: +0.000 to -0.022 mm\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\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 552\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: 9005520076000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51753162309938,"sku":"9005520076000","price":37.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/81bcc4f7fc5accb7f1bf7e46393b1cd0.jpg?v=1788933389","url":"https:\/\/voomisupply.com\/products\/guhring-9005520076000-stub-drill-bit-0-2992-in-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
