This is a sheet sander designed for detail sanding, finish prep, and controlled surface refinement. Model Number: MID3430201US. If you do woodworking, furniture work, window and door prep, or light drywall finishing where control matters more than brute size, this tool is aimed right at that kind of work.\u003c\/p\u003e\n    \u003cp\u003eMirka pairs a 3 x 4 inch sanding pad with a 3 mm orbit and a 10,000 RPM maximum speed, which tells you what this tool is really about: clean, controlled finish work. The smaller pad helps you get into corners, tighter profiles, and narrower workpieces where a larger random orbital sander feels clumsy. The fine orbit is there to help reduce visible swirl marks and leave a smoother surface that needs less rework before paint, stain, or final finish.\u003c\/p\u003e\n    \u003cp\u003eThe 250W brushless motor is a practical feature, not a buzzword. Brushless design means consistent output and less wear-related maintenance compared to brushed motors, and that matters on a sander that may spend hours doing repetitive finish prep. When you're trying to keep pressure even across trim, cabinet parts, furniture edges, or window components, steady motor performance helps the scratch pattern stay predictable.\u003c\/p\u003e\n    \u003cp\u003eAt about 2.14 lbs, this Mirka orbital sander is light enough for long sessions without wearing out your hand. That matters most on vertical work, edge sanding, and detail passes where a heavier tool starts fighting you. The ergonomic body and low-vibration focus also make a difference in real use. Better control usually means fewer sanding mistakes, less overcutting on edges, and more confidence when you're working on finish-sensitive material.\u003c\/p\u003e\n    \u003cp\u003eDust collection is one of the big reasons to step into a tool like this. The Mirka DEOS 343CV is built for dust-free sanding when connected to an extractor. On the job, that means better line of sight, less airborne dust settling back onto your work, and less cleanup at the end. If you're sanding indoors, in occupied spaces, or inside a shop where finish quality matters, that feature is not optional, it's one of the main reasons this tool earns its place.\u003c\/p\u003e\n    \u003cp\u003eThis model also offers Bluetooth connectivity for use with the myMirka app, which can monitor vibration levels and help track tool performance. That is especially useful for users who care about workflow consistency and jobsite exposure data, not just whether the tool turns on and sands. It's a practical layer of tool management for pros who use sanders daily.\u003c\/p\u003e\n    \u003cp\u003ePower comes from a 120V corded setup with a 14.4 ft power cord and a 2.5 amp draw, so this is a plug-in tool meant for steady shop or jobsite use without battery runtime limits. If you need a sander that stays ready all day for repetitive finish prep, that corded setup makes sense. It is a better fit for bench work, interior trim work, cabinetry, and production sanding than for roaming punch-list work where cordless freedom matters more than nonstop run time.\u003c\/p\u003e\n    \u003cp\u003eWho should buy it? Woodworkers, finish carpenters, cabinet installers, furniture refinishers, and serious DIY users who want a compact electric sander that can work cleanly and precisely. If your work regularly includes windows, doors, profiles, corners, narrow rails, and detailed surface prep, this Mirka sheet sander makes a strong case. If you mostly flatten large tabletops or strip broad open surfaces, you'd likely want a larger-format sander alongside it rather than using this as your only sanding tool.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails id=\"product-benefits\" class=\"acc\"\u003e\n  \u003csummary\u003e\u003ch2\u003eControl Tight-Space Sanding\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\/20260623022_1.jpg\" alt=\"Mirka DEOS 343CV electric orbital sander with 3 x 4 inch pad, cord, and abrasive sample for finish sanding wood trim and furniture parts in a workshop\" class=\"tnblock-img\"\u003e\n      \u003c\/div\u003e\n      \u003cdiv class=\"copy\"\u003e\n        \u003cp\u003eThe smaller 3 x 4 inch pad is what makes this sander useful where larger sanding tools start to get awkward.
