Built to DIN 6537L specification, it features a 140-degree split point (SU type) with web thinning for self-centering entry without a center punch. The FIREX coating provides thermal and wear resistance for extended tool life in production environments. With an overall length of 103 mm (4.055 inches) and a spiral flute design, this bit is suited for machinists, toolmakers, and fabricators working on precision drilling applications in a shop or manufacturing setting.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is designed for right-hand cutting in cast iron and steel workpieces. The 2-flute regular spiral configuration with a tapered web supports efficient chip evacuation during deep-hole passes. Coolant-through capability allows internal delivery of cutting fluid directly to the cutting zone, making it appropriate for CNC machining centers and high-cycle drilling operations where heat management is critical. The 5xD flute-to-diameter ratio provides adequate flute length for moderate-depth 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\u003c\/li\u003e\n  \u003cli\u003eFIREX coating for enhanced heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e140-degree SU split point with web thinning for self-centering entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design for internal cutting fluid delivery\u003c\/li\u003e\n  \u003cli\u003eRight-hand, 2-flute regular spiral for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eMeets DIN 6535 and DIN 6537 L standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for drilling cast iron and steel workpieces in CNC machining centers and conventional drill press setups that support straight-cylindrical shank tooling with coolant-through capability.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis bit is installed by machinists or toolroom personnel into compatible collet chucks or drill holders that accept a straight-cylindrical shank. Ensure the machine spindle is fully stopped and locked out before changing tooling. Verify coolant-through lines are clear and delivering adequate flow before beginning high-cycle operations. Do not exceed the maximum drilling depth of 47.95 mm (1.888 inches) per the flute geometry of this series.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.7 mm (0.3425 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 103 mm (4.055 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 61 mm (2.402 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40 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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 47.95 mm (1.888 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: Regular 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\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\u003eWeb Configuration\u003c\/strong\u003e: Tapered, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute-to-Diameter Ratio\u003c\/strong\u003e: 5xD\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron, Steel\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\u003eUNSPSC Code\u003c\/strong\u003e: 23241634\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 9055110087000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51738529792306,"sku":"9055110087000","price":308.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05221ee3ce3b80244db5048b38866d2c_10297f01-5b8b-400d-8a30-fe1d43589da5.jpg?v=1788800654","url":"https:\/\/voomisupply.com\/products\/guhring-9055110087000-carbide-jobber-drill-bit-8-7mm","provider":"Voomi Supply","version":"1.0","type":"link"}
