Built to DIN 6537L standards, it features a 140-degree split-point (SU) tip geometry with web thinning for self-centering entry without a center punch. The FIREX coating provides thermal and wear resistance, extending tool life in demanding production environments. At 4.8819 inches overall length with a 3.0315-inch flute length, this bit handles depths up to 2.305 inches in a single pass. The submicron carbide grade supports consistent performance at elevated cutting speeds. Two spiral flutes clear chips efficiently throughout the cut.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for primary use in cast iron and steel workpiece materials, covering material codes K and P. It fits standard CNC machining centers, drill presses, and rotary tool holders accepting a 0.5512-inch straight-cylindrical shank. The 5xD flute-to-diameter ratio and through-coolant capability make it well suited for close-tolerance production drilling in job shop and manufacturing environments. The Series 5511 designation places it within a professional tooling line intended for metalworking trades, tool-and-die work, and precision machining applications where dimensional accuracy and repeatability are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide construction for hardness and heat resistance in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eFIREX coating reduces friction and extends tool life under high-speed cutting conditions\u003c\/li\u003e\n  \u003cli\u003e140-degree SU point with web thinning enables self-centering entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capability supports deep-hole drilling with active chip and heat management\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank at 0.5512 inches diameter fits standard toolholders\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6535 and DIN 6537L standards for interchangeability and dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 6537L jobber-length replacement drill for CNC machining centers and drill presses accepting a 0.5512-inch straight-cylindrical shank.

Ensure the machine spindle and toolholder are fully powered down and locked out before inserting or removing the bit. Carbide tooling is brittle and should not be subjected to side-loading, interrupted cuts beyond its rated geometry, or impact during handling. Confirm through-coolant connections are active and flow is verified before initiating deep-hole drilling cycles.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 31\/64 inch (0.4844 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: 4.8819 inches (124 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.0315 inches (77 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.305 inches (58.55 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5512 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.8504 inches\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\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 5xD\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\/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\u003eCoolant Through\u003c\/strong\u003e: Yes\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\u003eSeries\u003c\/strong\u003e: 5511\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 6535, DIN 6537L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: DIN 6537L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.39 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: 9055110123000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51738570654002,"sku":"9055110123000","price":588.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05221ee3ce3b80244db5048b38866d2c_b216d41a-cc78-4ace-9f14-ad34d5259bf3.jpg?v=1788801136","url":"https:\/\/voomisupply.com\/products\/guhring-9055110123000-carbide-drill-bit-31-64-in-firex","provider":"Voomi Supply","version":"1.0","type":"link"}
