Cut 2 refers to the tooth coarseness grade on the Swiss-pattern scale, placing it in the second-cut range suitable for medium-fine stock removal and surface finishing. The file measures 5.5 inches overall length with a 2.5-inch length of cut, a 0.2-inch width, and a 0.06-inch thickness. It features a tang end for use with a separate handle. HVAC, tool-and-die, plumbing, and general mechanical tradespeople use Swiss-pattern needle files for deburring, fitting, and shaping metal components in confined areas.\u003c\/p\u003e\n\u003cp\u003eThis file is suited for precision work on metal parts where standard hand files are too coarse or too large. Typical applications include deburring copper fittings, cleaning threads, fitting valve seats, smoothing weld flash on thin stock, and refining machined surfaces. The half round profile gives the technician both a flat face and a curved face in a single tool, making it effective on both flat surfaces and concave or curved work pieces. It is commonly used in HVAC, plumbing, and light fabrication trades as well as in precision mechanical and electrical work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSwiss-pattern Cut 2 tooth grade for medium-fine stock removal and surface finishing\u003c\/li\u003e\n  \u003cli\u003eHalf round profile provides a flat face and a curved face in one file\u003c\/li\u003e\n  \u003cli\u003e5.5-inch overall length with 2.5-inch length of cut for use in confined spaces\u003c\/li\u003e\n  \u003cli\u003e0.2-inch width and 0.06-inch thickness suited for needle-file precision work\u003c\/li\u003e\n  \u003cli\u003eTang end accepts standard file handles for ergonomic grip\u003c\/li\u003e\n  \u003cli\u003eNeedle-file classification for high-precision, detail-level applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct addition to standard Swiss-pattern needle file sets used in HVAC, plumbing, electrical, and general mechanical trades.

File in one direction with controlled strokes to preserve tooth life and maintain surface finish quality. Keep the file clear of cutting oils or lubricants unless specifically required, as excess fluid can load the teeth. Store separately from other metal tools to prevent tooth damage.\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 Needle File\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFile Shape\u003c\/strong\u003e: Half Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCut\u003c\/strong\u003e: 2 (Medium-Fine)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTang Style\u003c\/strong\u003e: Tang (no handle included)\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: GROBET\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 31.520\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GROBET USA","offers":[{"title":"Default Title","offer_id":67915123196210,"sku":"31.520","price":34.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64c990b65556f8253aad71bc027560fa.jpg?v=1791252329","url":"https:\/\/voomisupply.com\/products\/grobet-31-520-swiss-pattern-needle-file-half-round-cut-2","provider":"Voomi Supply","version":"1.0","type":"link"}
