Warding files are slim, flat files with a rectangular cross-section and tapered width, designed specifically for filing key slots, narrow grooves, and tight clearances. At 3\/64 inches thick and 15\/32 inches wide, this file reaches confined areas where standard flat files cannot. It features a tang end for use with a compatible file handle. Locksmiths, machinists, and maintenance technicians reach for this tool when cutting or refining key bitmaps, slot profiles, and precision notches in metal workpieces.\u003c\/p\u003e\n\u003cp\u003eThis file is sized and profiled for key filing applications. The 4-inch length keeps the tool maneuverable in close quarters. The double cut pattern uses two sets of intersecting teeth that remove material faster than a single cut, while the smooth coarseness grade leaves a refined surface finish suitable for final fitting work on keys and precision slots. It is a standard hand tool addition for locksmiths, toolmakers, and trade professionals who require controlled, fine material removal in narrow channels.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4-inch length sized for close-quarters key and slot work\u003c\/li\u003e\n  \u003cli\u003eDouble cut tooth pattern for efficient material removal\u003c\/li\u003e\n  \u003cli\u003eSmooth coarseness grade for refined surface finish on final passes\u003c\/li\u003e\n  \u003cli\u003e3\/64-inch thickness allows entry into narrow keyway slots and grooves\u003c\/li\u003e\n  \u003cli\u003e15\/32-inch width provides a stable filing surface in warding profiles\u003c\/li\u003e\n  \u003cli\u003eTang end accepts a standard file handle for secure grip during use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an American-pattern warding file suitable for hand filing applications in key cutting, locksmithing, and precision metalwork where a slim, double-cut smooth file is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA file handle should be fitted to the tang before use to prevent hand injury from the bare tang point. Files are push-stroke tools — apply pressure on the forward stroke and lift or reduce pressure on the return stroke to preserve tooth sharpness. Always secure the workpiece in a vise or fixture before filing. Do not use this file on hardened steel above the file's own hardness rating, as this will damage the teeth.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFile Type\u003c\/strong\u003e: Warding\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFile Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCut Type\u003c\/strong\u003e: Double Cut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoarseness\u003c\/strong\u003e: Smooth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 3\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 15\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTang\/Handle\u003c\/strong\u003e: Tang\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: Key\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27111900\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: 16573NN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NICHOLSON","offers":[{"title":"Default Title","offer_id":51720670937394,"sku":"16573NN","price":26.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc22154c10874921431ad3bb523b55ea_0b325c83-6a36-4fde-a319-dce4e13cce41.jpg?v=1788567512","url":"https:\/\/voomisupply.com\/products\/nicholson-16573nn-warding-file-4-inches-double-cut-smooth","provider":"Voomi Supply","version":"1.0","type":"link"}
