Sized at 0.5000 inch (1\/2 inch) in diameter with a 140-degree split-point (SU) tip, it delivers self-centering entry without a center punch. The FIREX coating provides heat and wear resistance for extended tool life in production environments. Overall length is 4.88 inches (124 mm), with a flute length of 3.03 inches (77 mm) and a maximum drilling depth of 2.28 inches (57.95 mm). This bit is built to DIN 6537 L standards and is suited for machinists, tool-and-die professionals, and maintenance technicians running CNC or manual drilling operations.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for use in cast iron and steel workpiece materials, corresponding to material codes K and P. Its coolant-through design supports internal coolant delivery, making it a strong fit for CNC machining centers where through-spindle coolant is available. The 5xD flute-to-diameter ratio and regular spiral geometry promote efficient chip evacuation in deeper-hole drilling cycles. It is appropriate for both production machining and precision maintenance work where tool consistency and hole quality are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron-grade construction for rigidity and extended cutting life\u003c\/li\u003e\n  \u003cli\u003eFIREX coating for increased heat resistance and reduced tool wear in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split point enables self-centering entry without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant delivery for deep-hole drilling\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned, tapered web configuration reduces thrust force and improves chip flow\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard drill chucks and collet holders at 0.5512 inch shank diameter\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6535 and DIN 6537 L standards for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling cast iron and steel workpieces (material codes K and P) in accordance with DIN 6537 L.

Ensure the spindle is fully stopped and the machine is locked out before changing or inspecting the bit. Secure the straight-cylindrical shank firmly in the chuck or collet to the holder's rated clamping torque specification. When using coolant-through capability, confirm that the spindle coolant pressure and flow rate are within the machine tool manufacturer's recommended range before starting the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.5000 inch (1\/2 inch)\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: 4.88 inches (124 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 3.03 inches (77 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 2.28 inches (57.95 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5512 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.85 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 (Codes K and P)\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\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: 0.4 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: 9055110127000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51727214608690,"sku":"9055110127000","price":588.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05221ee3ce3b80244db5048b38866d2c_ba3c18d3-9ed6-4cc6-b7d5-ae2bc4050129.jpg?v=1788674814","url":"https:\/\/voomisupply.com\/products\/guhring-9055110127000-carbide-jobber-drill-bit-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
