Built to DIN 6537L standards, it features a 140-degree split point (SU type) with web thinning for self-centering entry without a center punch. The 5.4 mm diameter cutting edge is finished with a FIREX coating that extends tool life when working through abrasive or hardened materials. With a regular spiral flute and tapered web configuration, chip evacuation stays consistent through the full drilling depth. Licensed machinists and CNC operators working in job shops or production facilities are the primary installers of this tool.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is engineered for cutting cast iron and steel, matching material grade codes K and P. It suits horizontal and vertical machining centers, drill presses, and CNC lathes running coolant-through tooling setups. The 5xD flute-to-diameter ratio and 35.90 mm maximum drilling depth make it appropriate for medium-depth through-hole and blind-hole applications in ferrous materials. The straight-cylindrical shank seats securely in standard ER collets or drill chucks sized for a 6 mm bore.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide substrate for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eFIREX coating reduces friction and extends tool life in cast iron and steel\u003c\/li\u003e\n  \u003cli\u003e140-degree SU point with web thinning enables self-centering without spotting\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design channels fluid directly to the cutting edge\u003c\/li\u003e\n  \u003cli\u003eRegular spiral flute with tapered web for consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6535 and DIN 6537 L standards for shank and length geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for machining setups requiring a DIN 6537L jobber length drill in the 5.00 mm to 6.00 mm diameter range.

Power down and lock out the spindle before changing tooling. Confirm the collet or chuck bore matches the 6 mm straight-cylindrical shank diameter and that runout is within acceptable tolerance before initiating a cut. Engage coolant-through supply at the recommended flow rate for the workpiece material before starting the spindle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 5.4 mm (0.2126 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: 82 mm (3.2283 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 44 mm (1.7323 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 35.90 mm (1.4130 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2362 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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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\/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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter Tolerance\u003c\/strong\u003e: 0.004 to 0.016 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5511\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6535, DIN 6537 L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 9055110054000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51737441763634,"sku":"9055110054000","price":233.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05221ee3ce3b80244db5048b38866d2c_058f46a1-67fd-4623-8b50-22db416ebd0c.jpg?v=1788788604","url":"https:\/\/voomisupply.com\/products\/guhring-9055110054000-carbide-drill-bit-5-4-mm-firex","provider":"Voomi Supply","version":"1.0","type":"link"}
