This three-square (triangular) file features a Cut 4 double-cut tooth pattern, which produces a fine, smooth finish suited for deburring, refining edges, and working in tight angular spaces. At 6 inches in overall length with a 3\/8-inch wide body, it is a compact tool built for controlled hand-filing where accuracy matters. The tang end accepts a standard file handle. Machinists, toolmakers, die makers, and skilled trade professionals typically rely on Swiss-pattern files for exacting work that standard American-pattern files cannot achieve.\u003c\/p\u003e\n\u003cp\u003eThis file is appropriate for precision filing tasks on ferrous and non-ferrous metals, including steel, aluminum, brass, and hardened tool steel surfaces. The three-square profile allows access to internal corners, V-grooves, and angular slots where flat or half-round profiles cannot reach. The Cut 4 rating positions this file toward the fine end of the Swiss-pattern cut scale, making it best suited for finish work, light stock removal, and edge refinement rather than heavy material removal. It is commonly used in tool-and-die shops, maintenance facilities, and precision fabrication environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThree-square (triangular) profile for access to internal corners and angular grooves\u003c\/li\u003e\n  \u003cli\u003eCut 4 double-cut tooth pattern delivers fine, controlled material removal\u003c\/li\u003e\n  \u003cli\u003e6-inch overall length for compact handling in close-quarter filing\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch body width provides sufficient contact surface on narrow workpieces\u003c\/li\u003e\n  \u003cli\u003eTang end compatible with standard aftermarket file handles\u003c\/li\u003e\n  \u003cli\u003eSwiss-pattern construction for standard-precision metalworking and finishing tasks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose Swiss-pattern hand file for use with standard file handles in precision metalworking, toolmaking, and maintenance applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAlways fit a properly sized handle onto the tang before use to prevent hand injury. File in one direction with controlled forward strokes; avoid rocking the file across the workpiece to maintain a flat cutting action. Secure the workpiece in a vise or fixture before filing. Keep the file clean with a file card to maintain cutting efficiency and prevent pinning.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFile Type\u003c\/strong\u003e: Swiss-Pattern\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFile Shape\u003c\/strong\u003e: Three Square (Triangular)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCut Type\u003c\/strong\u003e: Double Cut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCut Number\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTang\/Handle\u003c\/strong\u003e: Tang\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLevel of Precision\u003c\/strong\u003e: Standard\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: GROBET\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 31.375\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GROBET USA","offers":[{"title":"Default Title","offer_id":67918840299826,"sku":"31.375","price":68.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82b53c078adef9df4606c7ccf3912982.jpg?v=1791273674","url":"https:\/\/voomisupply.com\/products\/grobet-31-375-swiss-pattern-file-6-in-three-square-cut-4","provider":"Voomi Supply","version":"1.0","type":"link"}
