Built to DIN 338 standards in M35 cobalt steel, this bit delivers reliable performance in tough workpiece materials where standard high-speed steel loses its edge. The two-flute, right-hand spiral design paired with a 118-degree four-facet split point and web-thinned tip reduces thrust and promotes accurate, self-centering entry. The straight-cylindrical shank measures 9\/32 inch and seats securely in standard drill chucks. Finished bright and uncoated, the bit is well-suited for applications where coating adhesion or contamination is a concern. Licensed tradespeople and machinists reaching for consistent, dimension-true holes will find this bit fits standard workflow on the floor or in the field.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for use in aluminum and non-ferrous metals as its primary workpiece materials, with material codes K, M, N, and P covered under its application range. The regular spiral and 5xD flute-to-diameter ratio support chip evacuation in those material families. With a flute length of approximately 2.72 inches and a maximum drilling depth of 2.295 inches, the bit handles typical jobber-length boring tasks in plate, billet, or structural stock. It is sold individually and packages at a minimal weight, making it easy to stock as a single-piece replacement or add to a drill index.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM35 cobalt steel construction for improved heat and wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003e118-degree four-facet split point with web thinning for reduced thrust and self-centering entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral, two-flute design promotes controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eBuilt to DIN 338 specification with a diameter tolerance of +0.000 to -0.022 mm\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard Jacobs-style and keyed drill chucks without adapters\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish maintains dimensional integrity and simplifies regrinding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style jobber length drill bit conforming to DIN 338 standards, compatible with any drill press, hand drill, or CNC spindle accepting a 9\/32 inch straight-cylindrical shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, maintenance mechanics, and metalworking tradespeople using standard drill chucks or collet holders. Ensure the chuck or collet is fully tightened and the shank is fully seated before operation. Set spindle speed appropriate to the workpiece material and bit diameter following published feeds-and-speeds references for cobalt tooling. Inspect the cutting edges before use and do not operate a chipped or re-ground bit beyond its serviceable diameter tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Letter)\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Inch)\u003c\/strong\u003e: 9\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Size (Decimal Inch)\u003c\/strong\u003e: 0.2812 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M35 Cobalt\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral (Regular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 69.00 mm (approximately 2.72 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 109.00 mm (approximately 4.29 inches)\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 (Inch)\u003c\/strong\u003e: 9\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 7.14 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.295 inches (58.29 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: +0.000 to -0.022 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum (Material Codes K, M, N, P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 338\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5523\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.042 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: 9055230071400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51753004728626,"sku":"9055230071400","price":21.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9d6b9f082d2d280c3429393fcd86ca44.jpg?v=1788932051","url":"https:\/\/voomisupply.com\/products\/guhring-9055230071400-cobalt-drill-bit-letter-k-9-32","provider":"Voomi Supply","version":"1.0","type":"link"}
