It carries a 0.2717-inch (Letter I) diameter, a 140-degree split point, and a coated finish that extends tool life under sustained cutting loads. The right-hand spiral flute geometry promotes efficient chip evacuation. At 79.00 mm overall length with a 34.00 mm flute length, this stub-length format offers increased rigidity compared to jobber-length alternatives. It is intended for use by machinists, tool-and-die professionals, and CNC operators who require consistent hole quality in ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis drill bit is rated for primary use in cast iron and steel workpieces. The screw machine length body reduces deflection during high-feed or high-spindle-speed operations, making it well suited for CNC machining centers, turret lathes, and production drilling fixtures where short-reach tooling is specified. The 3xD flute-to-diameter ratio and web-thinned parallel web configuration support aggressive material removal without sacrificing point stability. The straight-cylindrical shank with an 8.00 mm shank diameter seats directly in standard ER collets and drill chucks without adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction with submicron carbide grade for hardness and wear resistance in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e140-degree SU point with web thinning reduces entry thrust and improves self-centering on flat and curved surfaces\u003c\/li\u003e\n  \u003cli\u003eCoated finish extends cutting edge life under high-cycle production conditions\u003c\/li\u003e\n  \u003cli\u003eScrew machine (stub) length provides added rigidity and reduced deflection versus jobber-length equivalents\u003c\/li\u003e\n  \u003cli\u003eRight-hand, regular spiral flute promotes consistent chip flow out of the hole\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 6537 K specification for dimensional consistency and interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-specification replacement or new-installation tool for production drilling applications in cast iron and steel, conforming to DIN 6537 K standards.

Secure the shank fully in a collet or chuck to the manufacturer-recommended engagement depth before running the spindle. Carbide is brittle — avoid side loads, interrupted cuts at high feed rates, or re-chucking on a worn or contaminated bore without inspection. Confirm spindle runout is within acceptable tolerance before use, as excessive runout accelerates edge chipping on solid carbide tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 0.2717 inches (Letter I)\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\u003eTool Material\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eFlute Length\u003c\/strong\u003e: 34.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 79.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 8.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drilling Depth\u003c\/strong\u003e: 0.9310 inches (23.65 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute By Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeb Configuration\u003c\/strong\u003e: Parallel, Web-Thinned\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Length Type\u003c\/strong\u003e: Screw Machine\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: 5514\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: DIN 6537 K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 9055140069000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51728560062770,"sku":"9055140069000","price":161.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1722d1467d4ba478bd1f6fe04876cc3d_784a755a-5c0e-47ca-85cb-5ee1d27037fd.jpg?v=1788693350","url":"https:\/\/voomisupply.com\/products\/guhring-9055140069000-screw-machine-drill-bit-0-2717in","provider":"Voomi Supply","version":"1.0","type":"link"}
