Built from submicron-grade solid carbide and finished with a FIREX coating, this bit is designed to maintain edge life and dimensional accuracy under aggressive cutting conditions. It features a 140-degree split point (SU geometry) with web thinning for self-centering entry, eliminating the need for a center punch on most setups. The straight-cylindrical shank measures 0.3937 inches in diameter, and the overall length is 4.055 inches. With coolant-through capability and a regular spiral flute design, this bit supports through-tool coolant delivery for heat management during deep-hole operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is intended for professional machinists and toolroom technicians working with cast iron and steel workpieces. It fits CNC machining centers, drill presses, and manual lathes equipped for straight-shank tooling. The 5xD flute-to-diameter ratio and a maximum drilling depth of 1.894 inches (48.1 mm) make it well suited for medium-depth production drilling. It conforms to DIN 6537L and DIN 6535 standards, placing it within a recognized European precision tooling specification commonly specified in aerospace, automotive, and general metalworking shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron-grade solid carbide construction for superior hardness and wear resistance in ferrous materials\u003c\/li\u003e\n\u003cli\u003eFIREX coating extends tool life and reduces built-up edge when drilling cast iron and steel\u003c\/li\u003e\n\u003cli\u003e140-degree SU point geometry with web thinning enables self-centering entry without spot drilling\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports internal coolant delivery to the cutting zone\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, regular spiral flute with tapered web for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6537L and DIN 6535 standards for consistent dimensional interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style Series 5511 jobber drill bit for straight-shank tool holders compatible with 0.3937-inch shank diameter collets or drill chucks.

Ensure the collet or chuck is clean and free of chips before seating the straight-cylindrical shank. When using the coolant-through feature, verify that the machine spindle and toolholder are rated and configured for through-tool coolant delivery at the required pressure. Handle carbide tooling carefully to avoid edge chipping from contact with hard surfaces during storage and setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.6 mm (0.3386 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\u003eMaximum Drilling Depth\u003c\/strong\u003e: 48.1 mm (1.894 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40 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\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\u003ePoint Type\u003c\/strong\u003e: SU (Self-Centering)\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: Submicron-Grade Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\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: Yes\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\u003eSeries\u003c\/strong\u003e: 5511\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: DIN 6535, DIN 6537L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 9055110086000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51730456838450,"sku":"9055110086000","price":308.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05221ee3ce3b80244db5048b38866d2c_a1872557-0679-4e9e-86af-90e62c12af9e.jpg?v=1788717764","url":"https:\/\/voomisupply.com\/products\/guhring-9055110086000-carbide-jobber-drill-bit-8-6mm","provider":"Voomi Supply","version":"1.0","type":"link"}
