Sized at 0.375 inches (3\/8 inch) in diameter, the bit features a 118-degree four-facet split point that reduces walking and axial thrust at entry. Constructed from M35 cobalt high-speed steel, it delivers heat and wear resistance beyond standard HSS tooling. A web-thinned, tapered-web design lowers cutting force and improves chip evacuation through the spiral flutes. The bright\/uncoated finish is ready for use across a range of workpiece materials, with aluminum listed as the primary application material.\u003c\/p\u003e\n\u003cp\u003eThis bit is suited for production and job-shop environments where stub-length rigidity is preferred over longer drill geometries. The shortened flute length reduces deflection and chatter in CNC machining centers, drill presses, and handheld power tools where close-to-the-chuck reach is an advantage. With a maximum drilling depth of 1.131 inches (28.72 mm) and a flute-to-diameter ratio of 3xD, it is well matched to through-hole and blind-hole work in aluminum, non-ferrous metals, and general-purpose steel. The straight-cylindrical shank seats cleanly in standard drill chucks and collet systems without modification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM35 cobalt HSS construction for elevated heat resistance and extended tool life versus standard HSS\u003c\/li\u003e\n  \u003cli\u003e118-degree four-facet split point reduces drill walk and lowers thrust load at entry\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web design improves chip flow and reduces cutting force\u003c\/li\u003e\n  \u003cli\u003eDIN 1897 stub-length geometry provides added rigidity to minimize deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut with regular spiral flutes; diameter tolerance of +0.000 to -0.022 mm\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard three-jaw chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Series 5524 DIN 1897 stub-length replacement drill bit; compatible with any standard drill chuck or collet system accepting a 9.53 mm (0.375 inch) straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by a qualified machinist or tooling technician familiar with rotating cutting tools. Secure the shank fully in the chuck or collet and verify runout before beginning a cut. Always wear appropriate eye protection and ensure the workpiece is firmly fixtured before drilling. Follow machine manufacturer speed and feed recommendations for cobalt tooling in the workpiece material being drilled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 118 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePoint Type\u003c\/strong\u003e: Four Facet Split Point\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Cobalt HSS (M35)\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Regular Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9.53 mm (0.375 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 84.00 mm (3.307 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 40.00 mm (1.575 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.131 inches (28.72 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\u003eWeb Configuration\u003c\/strong\u003e: Tapered Web-Thinned\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\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\u003eSeries\u003c\/strong\u003e: 5524\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 1897\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.086 pounds\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: 9055240095200\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728613245234,"sku":"9055240095200","price":32.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a15d91b463dd3d24910fce830d22e233.jpg?v=1788693975","url":"https:\/\/voomisupply.com\/products\/guhring-9055240095200-cobalt-stub-drill-bit-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
