Built to DIN 6537 L standards, it features a 140-degree split point (SU) geometry with web thinning for self-centering entry and reduced thrust. The FIREX coating provides enhanced heat and wear resistance, extending tool life in abrasive materials. At 8.4 mm in diameter with a 4.0551-inch overall length and a 2.4016-inch flute length, this bit is sized for through-hole and blind-hole work in ferrous materials. It is installed by machinists and tool and die professionals in CNC and manual drilling operations.\u003c\/p\u003e\u003cp\u003eThis drill bit is designed for use in cast iron and steel workpieces, covering material grades classified under DIN codes K and P. The straight-cylindrical shank fits standard drill chucks and collet holders. With a 5xD flute-to-diameter ratio and a maximum drilling depth of 1.906 inches (48.4 mm), it handles moderate-depth holes common in structural components, fixtures, and machined parts. Coolant-through capability makes it well suited for high-speed production runs where chip evacuation and heat management are critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide submicron-grade construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eFIREX coating for extended tool life in ferrous and cast iron applications\u003c\/li\u003e\n\u003cli\u003e140-degree SU split point with web thinning for self-centering, low-thrust entry\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-speed drilling and efficient chip removal\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry promotes consistent chip evacuation\u003c\/li\u003e\n\u003cli\u003eConforms to DIN 6535 and DIN 6537 L standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a high-performance replacement-style jobber drill bit for drilling cast iron and steel in Series 5511 applications per DIN 6537 L specification, compatible with standard straight-cylindrical shank drill chucks and collet holders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and use of this drill bit should be performed by qualified machinists or tooling professionals. Secure the straight-cylindrical shank firmly in a properly sized chuck or collet before operation, and verify that runout is within acceptable tolerance for the application. Connect coolant-through supply if the machine spindle supports it to maximize tool life and chip clearance. Inspect the cutting edges for wear or chipping before each use and replace when dimensional accuracy can no longer be maintained.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.4 mm (0.3307 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 103 mm (4.0551 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 61 mm (2.4016 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 40 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 48.4 mm (1.906 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\u003eShank Diameter\u003c\/strong\u003e: 0.3937 inches\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 By Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter 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\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: 9055110084000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51737385369906,"sku":"9055110084000","price":313.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05221ee3ce3b80244db5048b38866d2c_53e03b85-feee-41bf-a598-be03e4032e59.jpg?v=1788787891","url":"https:\/\/voomisupply.com\/products\/guhring-9055110084000-carbide-jobber-drill-bit-8-4-mm","provider":"Voomi Supply","version":"1.0","type":"link"}
