This is a \u003cstrong\u003erandom orbital sander designed for spot repairs, body-in-white sanding, and post-paint applications\u003c\/strong\u003e. Model number \u003cstrong\u003eAROS325-B-NV\u003c\/strong\u003e. If you need a compact sanding tool that can move freely around a panel, part, or repair area without a hose or cord getting in the way, this is exactly the kind of machine that makes the job easier.\u003c\/p\u003e\n      \u003cp\u003eWhat makes this sander matter is the combination of a \u003cstrong\u003e3 inch (77 mm) backing pad\u003c\/strong\u003e, \u003cstrong\u003e2.5 mm orbit\u003c\/strong\u003e, and \u003cstrong\u003e12V brushless motor\u003c\/strong\u003e. That setup points this tool toward controlled surface prep and finishing rather than broad-area stock removal. The smaller pad helps you work tight areas and localized defects without sanding farther than you need to, and the 2.5 mm orbit is well suited to finer, more controlled sanding where surface quality matters.\u003c\/p\u003e\n      \u003cp\u003eMirka also built this unit around mobility and user comfort. The lightweight, ergonomic body is meant for one-handed use, and the low-vibration design helps reduce fatigue during repetitive sanding work. That matters in automotive and refinishing environments where you may be moving from one repair zone to the next all day and need the tool to stay comfortable and predictable in hand.\u003c\/p\u003e\n      \u003cp\u003eThe cordless layout is the real practical advantage here. On small repair work, dragging an air line or power cord around the vehicle, bench, or paint area wastes time and increases the chance of bumping finished surfaces. A cordless random orbital sander like this lets you grab the tool, hit the repair area, and move on. For techs doing spot correction or post-paint sanding, that kind of workflow improvement is not a small thing.\u003c\/p\u003e\n      \u003cp\u003eFor real-world shop conditions, Mirka notes sealed protection against \u003cstrong\u003edust and water\u003c\/strong\u003e, and the tool is suitable for both \u003cstrong\u003edry and wet sanding\u003c\/strong\u003e. That gives it more flexibility than a basic cordless sander, especially in refinishing work where process changes from one sanding stage to the next. The sealed design also makes more sense in dusty environments where fine sanding debris is part of the job every day.\u003c\/p\u003e\n      \u003cp\u003eThis sander also fits into the larger Mirka system. It is \u003cstrong\u003ecompatible with Mirka power tool batteries\u003c\/strong\u003e and works with the \u003cstrong\u003emyMirka app\u003c\/strong\u003e, which adds connectivity to Mirka's sanding ecosystem. If you are already using Mirka abrasives, accessories, or cordless tools, that shared platform is a real benefit. Just note that \u003cstrong\u003ebattery and charger are not included\u003c\/strong\u003e with this version.\u003c\/p\u003e\n      \u003cp\u003eWho should buy it? This is a smart pick for automotive refinishing pros, paint correction work, detail sanding, and anyone who needs a compact orbital sander for controlled surface prep in smaller areas. It also makes sense for serious users who already have Mirka batteries and want a purpose-built cordless sander instead of trying to force a larger general-use sander into precision work.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/details\u003e\n\n  \u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n    \u003csummary\u003e\u003ch2\u003eMade for Mobile Finish Work\u003c\/h2\u003e\u003c\/summary\u003e\n    \u003cdiv class=\"acc-body\"\u003e\n      \u003cdiv class=\"row\"\u003e\n        \u003cdiv class=\"img\"\u003e\n          \u003cimg src=\"https:\/\/cdn.anglera.com\/assets\/74d6ed76-fe0d-4d23-a9db-1f8749ca9ef2\/20260623042_1.jpg\" alt=\"Mirka AROS-B 325 3 inch max 12V Orbit 2.5 mm random orbital sander with compact backing pad for detail sanding and spot repair work in an automotive refinishing shop\" class=\"tnblock-img\"\u003e\n        \u003c\/div\u003e\n        \u003cdiv class=\"copy\"\u003e\n          \u003cp\u003eThe compact size is the whole point.
