The equalling profile features a rectangular cross-section with parallel edges and flat faces, making it well suited for smoothing flat surfaces, fitting close-tolerance joints, and refining inside corners. Cut 0 is a coarse-grade tooth pattern that removes material quickly while still delivering the controlled, consistent cut associated with Swiss-pattern manufacture. The file has an overall length of 6.25 inches with a 3-inch length of cut and terminates in a tang for use with a standard file handle.\u003c\/p\u003e\n\u003cp\u003eThis file is a common choice for machinists, tool and die makers, jewelers, and general metalworking trades that require repeatable, fine-control filing on ferrous and non-ferrous metals. The needle-file form factor suits benchtop and hand-held work where a full-size file would be too large for the task. It is appropriate for deburring, fitting mating parts, and finishing work in tight or recessed areas.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSwiss-pattern equalling profile with rectangular cross-section for flat-surface and close-tolerance work\u003c\/li\u003e\n  \u003cli\u003eCut 0 coarse tooth pattern for faster material removal with controlled cut\u003c\/li\u003e\n  \u003cli\u003e3-inch length of cut provides usable working surface for needle-file applications\u003c\/li\u003e\n  \u003cli\u003e6.25-inch overall length keeps the tool manageable for precision hand filing\u003c\/li\u003e\n  \u003cli\u003eTang end accepts standard file handles sold separately\u003c\/li\u003e\n  \u003cli\u003eNeedle-file precision level suitable for toolmaking and fine metalworking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style Swiss-pattern needle file suitable for use with standard aftermarket file handles sized for needle-file tangs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAlways seat the tang fully into a properly sized handle before use to prevent injury from an exposed tang. Secure the workpiece in a vise or fixture before filing to maintain control and accuracy. Files should be used with smooth, forward-stroke pressure only; dragging on the return stroke dulls the teeth prematurely. Do not use this file on hardened steel harder than the file itself, as this will damage the cutting teeth.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFile Type\u003c\/strong\u003e: Equalling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFile Shape\u003c\/strong\u003e: Rectangular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCut\u003c\/strong\u003e: 0 (Coarse)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLevel of Precision\u003c\/strong\u003e: Needle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 6.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHandle Style\u003c\/strong\u003e: Tang (no handle included)\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: 31.506\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GROBET USA","offers":[{"title":"Default Title","offer_id":67910059393330,"sku":"31.506","price":23.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e2b482530b3d526aaa2d22119108f966.jpg?v=1791195357","url":"https:\/\/voomisupply.com\/products\/grobet-31-506-equalling-swiss-pattern-needle-file","provider":"Voomi Supply","version":"1.0","type":"link"}
