Built to DIN 6537L standards, it features a 140-degree split-point (SU) geometry that is self-centering, reducing the need for a center punch on most surfaces. The FIREX coating improves wear resistance and heat management during extended drilling cycles. At 3.5827 inches overall length with a 2.0866-inch flute length, this bit delivers a 5xD depth-to-diameter ratio. Coolant-through capability makes it well suited for production environments where chip evacuation and tool life are critical. A tapered web and web-thinned tip reduce thrust and improve cutting efficiency.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is intended for use in cast iron and steel workpieces, covering primary material codes K and P. It fits standard jobber-length drilling applications in CNC machining centers, manual drill presses, and production-line setups where consistent tolerance and surface finish are required. The straight-cylindrical shank seats in standard collet chucks and drill chucks without modification. The Series 5511 designation places this bit in a family of long-series, submicron carbide tooling aimed at precision metal fabrication and general machining operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for hardness and edge retention in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eFIREX coating for enhanced heat and wear resistance in dry or minimum-quantity-lubrication applications\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split-point geometry provides self-centering entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal chip flushing for deep-hole and high-speed drilling\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web reduces axial thrust and improves chip breaking\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 6535 and DIN 6537 L standards for dimensional and geometric consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification jobber length drill bit for use in cast iron and steel; compatible with any standard straight-cylindrical shank toolholder, collet chuck, or drill chuck sized for a 0.3150-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by a qualified machinist familiar with carbide tooling handling procedures. Carbide is brittle and should not be subjected to side loads or impact; ensure the workpiece is fully secured before engaging the spindle. When using the coolant-through feature, confirm that coolant pressure and flow rate are matched to the machine spindle and toolholder specifications. Inspect the cutting edge for chipping before each use, as damaged carbide edges can cause workpiece damage or bit failure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.315 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5827 inches (91 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.0866 inches (53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.6140 inches (41 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.4961 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eMaterial\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\u003eCoolant Through\u003c\/strong\u003e: Yes\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: 0.006 to 0.021 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\u003eSeries\u003c\/strong\u003e: 5511\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 6535, DIN 6537 L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Number\u003c\/strong\u003e: DIN 6537L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 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: 9055110080000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51747407921458,"sku":"9055110080000","price":259.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05221ee3ce3b80244db5048b38866d2c_c9a06161-7a06-4f5e-bd3d-c69c2d2e6145.jpg?v=1788879641","url":"https:\/\/voomisupply.com\/products\/guhring-9055110080000-jobber-drill-bit-0-315in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
