This single-cut, bastard-grade file measures 8 inches in overall length with a 5\/16-inch diameter cutting surface. The tang end accepts a standard file handle, giving the technician a secure grip during use. Single-cut bastard files like this one are standard tools in metal fabrication shops, maintenance facilities, and field service kits where controlled material removal is required across ferrous and non-ferrous stock.\u003c\/p\u003e\n\u003cp\u003eThis file is suited for general machining tasks including enlarging holes, smoothing round openings, and fitting cylindrical surfaces. The round profile makes it effective for working inside curved cuts, pipe ends, and close-tolerance bores. The bastard cut provides an aggressive but controllable removal rate, making it appropriate for roughing passes before moving to finer finishing tools. Tradespeople in HVAC, pipefitting, and general mechanical maintenance commonly carry this file as part of a standard hand-tool set.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRound profile for shaping and enlarging curved surfaces and bores\u003c\/li\u003e\n  \u003cli\u003eBastard cut grade for efficient material removal on roughing passes\u003c\/li\u003e\n  \u003cli\u003eSingle-cut tooth pattern for controlled, directional filing action\u003c\/li\u003e\n  \u003cli\u003e8-inch cut length covers the full working surface of the file\u003c\/li\u003e\n  \u003cli\u003eTang end compatible with standard aftermarket and OEM file handles\u003c\/li\u003e\n  \u003cli\u003eRigid construction — no flex — for consistent contact and stroke control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard American-pattern round file suitable for use on ferrous and non-ferrous metals in general machining, fabrication, and maintenance applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eFiles should always be fitted with a handle before use to prevent tang injuries. Secure the workpiece in a vise when practical to maintain consistent stroke control and reduce fatigue. Do not use this file on hardened steel surfaces harder than the file itself, as this will damage the teeth. Inspect the file for cracks or missing teeth before each use and replace if the cutting surface is worn smooth.\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\u003c\/strong\u003e: Bastard Cut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 5\/16 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: Machining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 21853\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NICHOLSON","offers":[{"title":"Default Title","offer_id":51697278648626,"sku":"21853","price":90.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c8bb1ebaced867c04090d95c8a4873cb.jpg?v=1788351030","url":"https:\/\/voomisupply.com\/products\/nicholson-21853-round-bastard-cut-file-8-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
