Built to DIN 6537L standards, it features a 140-degree split-point (SU) 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. The bit measures 6.1 mm in diameter (0.2402 inches) with an overall length of 91 mm (3.58 inches) and a flute length of 53 mm (2.09 inches). Coolant-through capability supports high-speed machining operations where chip evacuation and heat management are critical.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for CNC machining centers, drill presses, and multi-spindle setups in job shops, tool rooms, and production machining environments. The straight-cylindrical shank with a 0.3150-inch diameter seats securely in standard ER collet chucks and drill chucks. The 5xD flute-to-diameter ratio and regular spiral flute geometry make it appropriate for through-hole and blind-hole applications in cast iron and steel workpieces. It is typically specified by machinists and tooling engineers for medium-to-high volume drilling programs where dimensional 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 edge retention in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eFIREX coating for elevated wear and oxidation resistance during high-speed drilling\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split-point with web thinning enables self-centering entry and reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports internal coolant delivery for chip flushing and heat control\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537L and DIN 6535 standards for consistent dimensional tolerancing\u003c\/li\u003e\n  \u003cli\u003eDiameter tolerance held to 0.006 to 0.021 mm for repeatable hole sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron and steel workpieces per primary workpiece material codes K and P.

Ensure the machine spindle and toolholder are clean and within runout tolerance before seating the shank, as carbide is brittle and sensitive to lateral loading from excessive runout. Activate coolant-through supply before engaging the cut when using internal coolant. Do not use this bit in hand-held drills or applications outside its rated material and depth specifications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 6.1 mm (0.2402 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 91 mm (3.58 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 53 mm (2.09 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm (1.42 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 43.85 mm (1.726 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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Submicron Grade\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 6537L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 9055110061000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748055810354,"sku":"9055110061000","price":260.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05221ee3ce3b80244db5048b38866d2c_baa48fdc-1867-471e-a05e-b45074c4fd16.jpg?v=1788888534","url":"https:\/\/voomisupply.com\/products\/guhring-9055110061000-carbide-jobber-drill-bit-6-1mm","provider":"Voomi Supply","version":"1.0","type":"link"}
