Built to DIN 6537L standards, it features a 6.6 mm diameter, a 140-degree split-point (SU) tip geometry, and a FIREX coating that extends tool life in demanding production environments. The submicron carbide grade and web-thinned, tapered web construction reduce entry force and improve chip evacuation. Coolant-through capability supports sustained drilling at higher feeds and speeds. This bit is sized for precision work with a diameter tolerance of 0.006 to 0.021 mm, making it a reliable choice for machinists and tool-room technicians running automated or manual drilling operations.\u003c\/p\u003e\u003cp\u003eThe 9055110066000 is suited for drilling cast iron and steel in both production-shop and maintenance environments. Its 5xD flute-to-diameter ratio and self-centering point geometry make it effective in applications where hole positioning accuracy and consistent depth control are required. The straight-cylindrical shank seats in standard drill chucks and collet holders without modification, allowing drop-in use on CNC machining centers, drill presses, and hand-held power tools where shank diameter accommodates the 0.315-inch shank.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFIREX coating for improved wear resistance and heat management in steel and cast iron\u003c\/li\u003e\n\u003cli\u003e140-degree SU split-point tip for self-centering entry and reduced thrust force\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip flushing and heat control at depth\u003c\/li\u003e\n\u003cli\u003eWeb-thinned tapered web reduces drilling torque and extends tool life\u003c\/li\u003e\n\u003cli\u003eSubmicron solid carbide grade delivers consistent performance in high-hardness materials\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537L and DIN 6535 standards for dimensional reliability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in drilling cast iron and steel workpieces; primary workpiece material codes K and P.

Ensure the machine spindle and workholding are fully stopped and secured before inserting or removing the bit. Carbide tooling is brittle and susceptible to chipping from lateral shock or improper clamping; verify runout and chuck concentricity before operation. Always apply coolant through the spindle when the machine supports it to maximize tool life at the rated drilling depth.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.6 mm (0.2598 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 91 mm (3.583 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53 mm (2.087 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 43.1 mm (1.697 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.315 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Point Angle\u003c\/strong\u003e: 140 degrees\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\u003ePoint Type\u003c\/strong\u003e: SU (Self-Centering)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\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\u003eStandard\u003c\/strong\u003e: DIN 6537L, DIN 6535\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5511\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\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 9055110066000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730422792498,"sku":"9055110066000","price":259.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05221ee3ce3b80244db5048b38866d2c_9594429e-e534-435b-a604-1fab31a7c6a7.jpg?v=1788717191","url":"https:\/\/voomisupply.com\/products\/guhring-9055110066000-carbide-jobber-drill-bit-6-6-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
