Built to DIN 6537L standards, it features a 140-degree split-point (SU) geometry with web thinning for self-centering entry without a pilot hole. The FIREX coating improves heat resistance and extends tool life in abrasive applications. At 4.9 mm in diameter with a 6.0 mm straight-cylindrical shank, it runs in standard drill chucks or collet holders. Two spiral flutes in a regular helix provide efficient chip evacuation. The overall length is 82.0 mm with a 44.0 mm flute length, supporting a maximum drilling depth of 40.0 mm.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for cast iron and steel workpiece materials, corresponding to material codes K and P. It is a high-performance, submicron-grade carbide tool suited to production machining, tool rooms, and maintenance shops where dimensional accuracy and tool life matter. The 5xD flute-to-diameter ratio and tapered web configuration make it appropriate for through-hole and blind-hole drilling in CNC machining centers, drill presses, and hand-held power tools when rigid fixturing is used. It is sold and packaged as a single unit.\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 for elevated heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split-point with web thinning for self-centering, reduced thrust force\u003c\/li\u003e\n  \u003cli\u003eTwo regular-spiral flutes with a 5xD ratio for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical 6.0 mm shank compatible with standard collet and drill-chuck toolholders\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537L and DIN 6535 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a DIN 6537L Series 5515 jobber-length drill bit for use in cast iron and steel (material codes K and P).

Ensure the machine spindle is fully stopped and locked out before loading or removing the bit. Carbide tooling is brittle and should not be used in setups where lateral loading or tool deflection is likely, as this can cause chipping or fracture. Confirm shank seating depth and runout before beginning a production run.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.9 mm (0.1929 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 82.0 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 44.0 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 40.0 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6.0 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36.0 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\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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 5515\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6537L, DIN 6535\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: 9055150049000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51735242670386,"sku":"9055150049000","price":152.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7a011e334b6e0cfd7c233ace7256d4a_8955965f-103d-4eb7-b5ac-f245d518958d.jpg?v=1788770814","url":"https:\/\/voomisupply.com\/products\/guhring-9055150049000-carbide-drill-bit-4-9-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
