Built to DIN 6537L standards, it features a 140-degree split-point (SU) geometry with web thinning for self-centering entry, reducing the need for a center punch on most setups. The bit carries a FIREX coating for improved wear resistance and heat dissipation at the cutting edge. At 0.3937 inches in diameter with a 4.0551-inch overall length, it is sized for production drilling in cast iron and steel. Coolant-through capability supports high-feed operations where chip evacuation and thermal management are critical.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for CNC machining centers, drill presses, and other machine-tool setups running production volumes in metal fabrication, tool and die, automotive, and industrial manufacturing environments. The straight-cylindrical shank fits standard collets and chucks without modification. Its 5xD flute-to-diameter ratio and regular spiral flute geometry make it appropriate for medium-depth holes in cast iron and steel workpieces where surface finish and dimensional accuracy are required. Machinists and toolroom professionals working with P- and K-category materials per ISO classification will find this geometry well matched to those applications.\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 hard materials\u003c\/li\u003e\n  \u003cli\u003eFIREX coating reduces friction and extends tool life in ferrous materials\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split-point with web thinning enables self-centering without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design supports chip evacuation and thermal control at depth\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, regular spiral flute with tapered web configuration\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 6535 and DIN 6537 L standards for consistent dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron and steel workpieces (ISO material groups K and P).

Secure the shank fully in the collet or chuck before operation and verify runout is within acceptable limits, as carbide is brittle and sensitive to lateral loading. Coolant-through capability requires a machine spindle with internal coolant delivery to be active. Do not use this bit for freehand drilling or in handheld equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.3937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0551 inches (103 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.4016 inches (61 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 1.8110 inches (46 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1.6535 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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\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\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\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 Designation\u003c\/strong\u003e: DIN 6537L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 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: 9055110100000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748778017074,"sku":"9055110100000","price":400.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05221ee3ce3b80244db5048b38866d2c_36a77e8e-02ba-4651-938e-4719d33a45f1.jpg?v=1788898231","url":"https:\/\/voomisupply.com\/products\/guhring-9055110100000-carbide-jobber-drill-bit-0-3937in","provider":"Voomi Supply","version":"1.0","type":"link"}
