Built to DIN 6537L standards, this bit features a 140-degree split point (SU type) with web thinning for self-centering entry without a center punch. The FIREX coating reduces friction and extends tool life in demanding applications. At 4 mm in diameter with a 74 mm overall length and a 36 mm flute length, it handles maximum drilling depths up to 30 mm. The submicron carbide grade delivers consistent performance in both interrupted and continuous cuts.\u003c\/p\u003e\u003cp\u003eThis drill bit is suited for drilling cast iron and steel in production and job-shop environments. The straight-cylindrical shank at 6 mm diameter seats securely in standard drill chucks and collet holders. The 5xD flute-to-diameter ratio and regular spiral geometry promote efficient chip evacuation in through-hole and blind-hole applications. It is appropriate for CNC machining centers and manual drill presses operated by machinists, toolmakers, and metalworking professionals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid submicron carbide construction for rigidity and wear resistance in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eFIREX coating for reduced friction and extended tool life\u003c\/li\u003e\n\u003cli\u003e140-degree SU split point with web thinning for self-centering entry\u003c\/li\u003e\n\u003cli\u003eRight-hand, regular spiral flutes for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 6 mm shank compatible with standard chucks and collet systems\u003c\/li\u003e\n\u003cli\u003eManufactured to DIN 6535 and DIN 6537L standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard drill chucks and collet holders accepting a 6 mm straight-cylindrical shank.

Secure the shank fully in the chuck or collet and verify runout before operation. Always bring spindle speed and feed rate into the range appropriate for carbide tooling in the workpiece material being drilled. Power down and lock out the machine before changing or inspecting the bit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4 mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 74 mm (2.913 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 36 mm (1.417 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 6 mm (0.236 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 36 mm (1.417 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 30 mm (1.181 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\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\u003eCoating\/Finish\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\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\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\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\u003eStandards\u003c\/strong\u003e: DIN 6535, DIN 6537L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5515\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\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: 9055150040000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51750180716850,"sku":"9055150040000","price":144.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7a011e334b6e0cfd7c233ace7256d4a_d94a2884-c072-4ea0-b006-2d3d24fc554f.jpg?v=1788914130","url":"https:\/\/voomisupply.com\/products\/guhring-9055150040000-carbide-drill-bit-4-mm-firex","provider":"Voomi Supply","version":"1.0","type":"link"}
