It features a 140-degree split point geometry with web thinning for self-centering entry, eliminating the need for a center punch on most applications. The cutting edges carry a FIREX coating that extends tool life in abrasive and hard materials. At 118 mm overall length with a 71 mm flute length, this is a standard jobber format suited for CNC machining centers and drill presses. It is part of the Guhring Series 5515, built to DIN 6537 L and DIN 6535 standards using a submicron carbide grade.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for cutting cast iron and steel, corresponding to ISO material codes K and P. The 5xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes up to 54.50 mm. The straight-cylindrical shank at 12 mm diameter fits standard ER collet chucks and drill chuck toolholders. Typical users include machinists, toolroom technicians, and CNC operators working in production or job shop environments on ferrous workpieces where carbide tooling is specified over high-speed steel.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for rigidity and wear resistance in cast iron and steel\u003c\/li\u003e\n  \u003cli\u003eFIREX coating reduces friction and extends cutting edge life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e140-degree split point with web thinning enables self-centering without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eSpiral flute, right-hand cut, regular helix for consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 12 mm shank fits standard collet and chuck toolholding\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537 L and DIN 6535 standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers, drill presses, and hand-held power tools accepting a 12 mm straight-cylindrical shank.

Seat the straight shank fully and evenly in the collet or chuck before tightening to manufacturer-specified clamping torque for the toolholding system in use. Inspect the cutting edges and coating for chips or wear before each use, as carbide is brittle and a damaged edge can fracture under load. Follow machine manufacturer guidelines and applicable shop safety procedures when setting speeds and feeds for carbide tooling in ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.4331 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 118 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 71 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.1460 inches (54.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 45 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Spiral, Regular Helix\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: SU (Self-Centering)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.007 to 0.025 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5515\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 6537 L, DIN 6535\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.28 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: 9055150110000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732991017266,"sku":"9055150110000","price":330.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7a011e334b6e0cfd7c233ace7256d4a_3f899d00-be4d-4cbc-89fe-9894f7a2ddc2.jpg?v=1788750130","url":"https:\/\/voomisupply.com\/products\/guhring-9055150110000-carbide-jobber-drill-bit-0-4331in","provider":"Voomi Supply","version":"1.0","type":"link"}
