Built to DIN 6537 L standards, it features a 4.4 mm diameter, a 140-degree split point (SU type), and a FIREX coating that extends tool life in abrasive and hard materials. The two-flute, right-hand spiral design promotes efficient chip evacuation, while web thinning reduces entry force and improves self-centering performance. This bit is intended for use by machinists and tool-and-die professionals working on precision drilling operations in production environments.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is suited for drilling cast iron and steel workpieces in both light manufacturing and heavy production settings. The 5xD flute-to-diameter ratio and a maximum drilling depth of 32 mm make it appropriate for moderate-depth holes in ferrous materials. The straight-cylindrical shank at 6 mm diameter seats reliably in standard drill chucks and collet holders. It conforms to DIN 6535 and DIN 6537 L specifications, making it a direct fit for tooling setups that require metric DIN-standard tooling.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide submicron-grade construction for rigidity and wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eFIREX coating reduces heat buildup and extends service life in cast iron and steel applications\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split point provides self-centering entry without a center punch in most setups\u003c\/li\u003e\n  \u003cli\u003eWeb-thinned tapered web reduces thrust load and improves chip flow at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flute with regular helix angle promotes consistent chip evacuation\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6535 and DIN 6537 L for dimensional standardization across metric tooling setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in cast iron and steel workpieces.

Ensure the machine spindle and workpiece are properly secured before beginning any operation. Confirm chuck or collet runout is within acceptable tolerance before seating the shank, as excessive runout accelerates carbide wear. Do not use this bit without confirming the spindle speed and feed rate are appropriate for the workpiece material and bit diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 4.4 mm (0.1732 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: 32 mm (1.260 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 Helix\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\u003eDrill Bit Material\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\u003eStandards\u003c\/strong\u003e: DIN 6535, DIN 6537 L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Number\u003c\/strong\u003e: 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: 0.07 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: 9055150044000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730623660338,"sku":"9055150044000","price":152.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7a011e334b6e0cfd7c233ace7256d4a_6b4cf6c3-8b75-493e-87f4-27ed284f2653.jpg?v=1788720449","url":"https:\/\/voomisupply.com\/products\/guhring-9055150044000-carbide-drill-bit-4-4-mm-firex","provider":"Voomi Supply","version":"1.0","type":"link"}
