Built to DIN 6537K standards, it features a 140-degree split point (SU type) with web thinning for reduced thrust and improved centering. The 2-flute spiral design runs coolant through the body, making it well-suited for production environments where heat management is critical. At 7.70 mm (0.3031 inches) in diameter with a straight-cylindrical shank, this bit fits standard toolholders without adapters. Machinists and CNC operators in metal fabrication and manufacturing shops are the primary users.\u003c\/p\u003e\u003cp\u003eThis drill bit is built for screw machine length applications where a compact overall length provides rigidity and reduces deflection. It targets ferrous materials including cast iron and steel, common in production machining, job shops, and automated CNC operations. The 3xD flute-to-diameter ratio and parallel web configuration support consistent chip evacuation in deeper cuts up to 38.00 mm. The Series 5510 designation places it in the high-performance tier of the Guhring carbide drill lineup.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with submicron grain material grade for edge retention in ferrous materials\u003c\/li\u003e\n\u003cli\u003e140-degree SU point with web thinning reduces entry thrust and self-centers on contact\u003c\/li\u003e\n\u003cli\u003eThrough-coolant capable for extended tool life in high-speed production runs\u003c\/li\u003e\n\u003cli\u003eScrew machine length (79.00 mm overall) provides added rigidity over jobber-length bits\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 2-flute spiral flute design promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMeets DIN 6537K specification for dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit option for standard straight-cylindrical shank toolholders accepting an 8.00 mm shank diameter, suitable for CNC machining centers and screw machine applications targeting cast iron and steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified machinists following shop safety procedures. Secure the straight-cylindrical shank fully in a compatible collet or drill chuck rated for the intended spindle speed before operation. Verify coolant line connections are clear and pressurized before engaging through-coolant flow. Do not exceed the maximum drilling depth of 38.00 mm in a single pass without retracting to clear chips.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 7.70 mm (0.3031 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 79.00 mm (3.11 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 41.00 mm (1.61 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 38.00 mm (1.50 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm (0.31 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeb Thinning\u003c\/strong\u003e: Web-Thinned\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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\u003eStandard\u003c\/strong\u003e: DIN 6537K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5510\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: 9055100077000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51735653384498,"sku":"9055100077000","price":224.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5a421e41410bd1760dd91da72036eb28_586e7a68-34ae-4e51-be72-8756a82a3877.jpg?v=1788773467","url":"https:\/\/voomisupply.com\/products\/guhring-9055100077000-carbide-screw-machine-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
