Built to DIN 6537L specification, it features a 140-degree split point (SU type) with web thinning for reduced thrust and cleaner entry. The FIREX coating adds thermal resistance and wear protection, extending tool life in ferrous and hardened materials. The submicron carbide grade provides rigidity and edge retention that standard HSS tooling cannot match. A straight-cylindrical shank measuring 10 mm in diameter ensures secure chuck retention on most standard setups. This bit is suited for machinists, tool-and-die shops, and CNC operators working in production or precision environments.\u003c\/p\u003e\u003cp\u003eThis drill bit is used in applications requiring tight-tolerance hole making in materials such as steel alloys, cast iron, and stainless steel. The 5xD flute-to-diameter ratio and 57 mm maximum drilling depth make it suitable for moderately deep holes in production machining, fixture building, and general metalworking. The right-hand spiral flute geometry promotes efficient chip evacuation during through-hole and blind-hole operations. Coolant-through capability is not available on this model, so external coolant or cutting fluid application is recommended for heat management in harder materials.\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 thermal protection and extended tool life\u003c\/li\u003e\n\u003cli\u003e140-degree SU point with web thinning for reduced entry thrust\u003c\/li\u003e\n\u003cli\u003eDIN 6537L specification for consistent dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical 10 mm shank for broad chuck compatibility\u003c\/li\u003e\n\u003cli\u003eRegular spiral flute geometry for efficient chip removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a jobber length drill bit for use in standard drill chucks and collet holders accepting a 10 mm straight-cylindrical shank, suitable for CNC machining centers, drill presses, and manual lathes configured for metalworking.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed with the machine powered down and locked out. Secure the shank fully within the chuck or collet to the recommended grip depth before operation. External cutting fluid or coolant is recommended during use, as this bit does not support coolant-through delivery. Inspect the cutting edges for chipping or wear before each use, as carbide tooling can fracture if operated with a damaged edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 8.9 mm (0.3504 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 103 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 61 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 57 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\u003ePoint Type\u003c\/strong\u003e: SU\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\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\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\u003eDiameter Tolerance\u003c\/strong\u003e: 0.006 to 0.021 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 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: 0.2 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: 9055150089000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51750144639282,"sku":"9055150089000","price":260.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/35f302d4c73343a1bd9a70006e936166_1ae54dcc-963b-4772-b51a-b2c2b1ea124e.jpg?v=1788913813","url":"https:\/\/voomisupply.com\/products\/guhring-9055150089000-carbide-jobber-drill-bit-8-9mm","provider":"Voomi Supply","version":"1.0","type":"link"}
