This single-cut, bastard-cut file measures 6 inches in overall length with a 4.5-inch cutting surface, giving the technician or machinist an efficient tool for controlled stock removal on metals, plastics, and similar materials. The ergonomic handle is included, providing a secure grip during use. At 0.19 pounds, it is lightweight and easy to maneuver in tight work areas. Single-cut files like this one produce a smoother finish than double-cut styles, making them a common choice for finishing passes and precision fitting work.\u003c\/p\u003e\n\u003cp\u003eThis file is suited for use in machine shops, maintenance facilities, and general metalworking environments where round-profile filing is required. Typical applications include enlarging or finishing round openings, smoothing drilled holes, and shaping curved surfaces. The bastard cut is a mid-coarseness grade that balances material removal rate with surface finish quality, making it appropriate for a wide range of ferrous and non-ferrous metals encountered in machining and repair work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRound profile for filing curved surfaces, holes, and round-profile slots\u003c\/li\u003e\n  \u003cli\u003eBastard cut grade balances stock removal with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eSingle-cut tooth pattern produces a smoother finish than double-cut files\u003c\/li\u003e\n  \u003cli\u003e4.5-inch length of cut provides adequate working surface for most applications\u003c\/li\u003e\n  \u003cli\u003eErgonomic handle included for secure grip and reduced hand fatigue\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.19 pounds for easy one-handed use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard American-pattern round file for general machining and metalworking applications where a 6-inch bastard-cut single-cut round file with handle is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFiles are hand tools installed by machinists, maintenance technicians, and metalworkers without power tools. Always inspect the file for cracks or damaged teeth before use and ensure the handle is fully seated on the tang before applying pressure. Never use a file without a handle, as an exposed tang can cause serious hand injury. Store files individually or separated to prevent tooth-to-tooth contact, which dulls cutting edges prematurely.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFile Type\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCut Type\u003c\/strong\u003e: Single Cut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoarseness \/ Cut Grade\u003c\/strong\u003e: Bastard Cut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width \/ Diameter\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 1.13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Style\u003c\/strong\u003e: Ergonomic, included\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlexible\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Machining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 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: NICHOLSON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 21708NN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NICHOLSON","offers":[{"title":"Default Title","offer_id":51720827666738,"sku":"21708NN","price":22.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/27142b40be4fa7204c1439dbf652fe2f_dc044f77-0594-4200-a589-efbf2fc74933.jpg?v=1788569661","url":"https:\/\/voomisupply.com\/products\/nicholson-21708nn-round-file-6-in-bastard-cut-single","provider":"Voomi Supply","version":"1.0","type":"link"}
