Built from submicron carbide and finished with a FIREX coating, this bit delivers extended tool life and heat resistance in ferrous materials. It features a 140-degree split point (SU point type) with web thinning for self-centering entry without a center punch. The overall length is 91 mm with a 53 mm flute length and a straight-cylindrical shank diameter of 8 mm. Right-hand spiral flutes in a regular helix pattern evacuate chips efficiently. Licensed HVAC, machining, and fabrication trades use this bit in CNC drilling centers and manual machines alike.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for drilling cast iron and steel workpieces, meeting the applications where materials fall under ISO material codes K and P. The 5xD flute-to-diameter ratio and 42.50 mm maximum drilling depth make it well-suited for through-hole and moderate-depth blind-hole operations in structural steel fabrication, general machining, and component manufacturing. It conforms to DIN 6537 L and DIN 6535 standards, making it a direct fit for toolholders and collets dimensioned to those specifications. Series 5515 identifies the GUHRING product family for this high-performance carbide drill line.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron solid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eFIREX coating improves heat resistance and extends tool life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split point with web thinning enables self-centering without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral flutes promote efficient chip evacuation in deep holes\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank (8 mm) for secure seating in standard drill chucks and collets\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 cast iron and steel workpieces (ISO material codes K and P).

Secure the straight-cylindrical shank fully in the collet or drill chuck before operation, and confirm runout is within acceptable tolerance for the application. No coolant-through capability is present on this tool, so external cutting fluid or mist coolant should be applied when drilling deep holes in steel to manage heat. Inspect the cutting edges and FIREX coating before each use and replace at first signs of edge wear to avoid workpiece damage or bit breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2756 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\u003ePoint Type\u003c\/strong\u003e: SU (Self-Centering)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 91 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 42.50 mm (1.6730 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\/Finish\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-to-Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003eDiameter Tolerance\u003c\/strong\u003e: 0.006 to 0.021 mm\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\u003eSeries\u003c\/strong\u003e: 5515\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: 0.1 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: 9055150070000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51747979559218,"sku":"9055150070000","price":195.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7a011e334b6e0cfd7c233ace7256d4a_470db3db-1a79-4e89-bd8b-55d34f0079ae.jpg?v=1788887680","url":"https:\/\/voomisupply.com\/products\/guhring-9055150070000-carbide-jobber-drill-bit-0-2756in","provider":"Voomi Supply","version":"1.0","type":"link"}
