Intro
Not every sanding job calls for an aggressive random orbital machine. When you are working on fine woodworking projects, smoothing between coats of varnish, or sanding right up to the corners of a door frame, a finishing sander with a flat, rectangular pad gives you the control and precision that round orbital sanders cannot match. Sheet sanders — sometimes called finishing sanders or orbital palm sanders — use a simple back-and-forth vibrating motion rather than a spinning disc. This produces a finer, more uniform scratch pattern and lets you work into corners and along edges where a round pad would leave unsanded crescents. They run faster than random orbitals — typically 14,000 orbits per minute — and are quieter and less aggressive, making them the tool of choice for cabinet makers, furniture restorers, and painters who need a glass-smooth surface without the risk of cutting too deep. A good corded sheet sander is lightweight, low-vibration, and takes standard sandpaper sheets that cost pennies each — an essential complement to any woodworking toolkit.
Generalities
Sheet sanders are the traditional workhorses of fine finishing. Unlike random orbital sanders that combine rotation with oscillation, a sheet sander uses a pure orbital vibration — the pad moves in tiny circles or ellipses without spinning. The result is a finer finish with less risk of leaving visible scratch marks, but at the cost of slower material removal. The key specifications are the motor power (200 watts is typical for a 1/3-sheet format), the orbit rate (usually 12,000 to 14,000 orbits per minute), the pad size (100 by 164 millimetres for standard 1/3-sheet sanders), and the paper clamping mechanism. A good sheet sander should weigh around 1.2 kilograms — light enough for one-handed vertical use — and have effective vibration damping. Makita's BO4566 is a classic example of the category: a straightforward, corded 200-watt sheet sander that has been a staple in workshops for years, earning a 4.4 out of 5 stars rating from nearly 900 reviews.
This review takes a close look at the Makita BO4566: its 14,000 OPM single-speed performance, the 100 by 164 millimetre pad format, ergonomics and vibration control at just 1.2 kilograms, the paper clamping system, and how it handles typical finishing tasks from between-coat sanding to fine wood preparation. If you are building out a sanding toolkit and wondering whether a dedicated sheet sander earns its keep alongside a random orbital, this review will help you decide.
Description
The Makita BO4566 is a 200-watt corded finishing sander in the 1/3-sheet format, built around a simple, reliable orbital mechanism that vibrates the pad at 14,000 orbits per minute. The pad measures 100 by 164 millimetres — the standard size for a 1/3-sheet sander, meaning you can cut a standard 280 by 230 millimetre sandpaper sheet into three equal pieces and clamp each one into the tool. This makes consumables both cheap and easy to find: any hardware store stocks sandpaper sheets in a full range of grits, and you can cut your own or buy pre-cut 1/3-sheet packs. The motor is corded electric running on standard 230-volt mains power, giving you unlimited runtime without batteries to manage — ideal for long finishing sessions where consistency matters more than portability.
The BO4566 keeps things refreshingly simple. The rectangular body has a flat top with a palm rest that puts your hand directly over the pad for even pressure distribution — essential for a tool designed to produce a uniform finish without digging in. Weighing just 1.2 kilograms, it is one of the lightest sanders in Makita's lineup, making it comfortable for extended vertical and overhead use. The paper clamping system uses spring-loaded metal clips at the front and rear of the pad — a proven design that holds the paper tight without the complexity of hook-and-loop systems. While hook-and-loop is faster for pad changes, the clamp system ensures the paper absolutely cannot shift or peel during use, which matters when you are chasing a flawless final surface. The on-off switch is a simple rocker on the top of the body, positioned for thumb access.
In daily use, the single-speed 14,000 OPM design is both a limitation and a strength. There is no dial to fiddle with, no settings to second-guess — just turn it on and sand. The high orbit rate means even with fine 320 or 400-grit paper, the sander moves fast enough to produce a smooth surface quickly without gouging. For between-coat sanding on paint or varnish, the light weight and flat pad make it easy to kiss the surface with just enough pressure to de-nib without cutting through to the layer below. The rectangular shape reaches right into corners and along edges — think the inside corner of a cabinet carcass or the edge of a door panel — where a round random orbital pad would leave an unsanded arc. The vibration level is well-controlled for a tool of this type, though the 14,000 OPM rate naturally produces more of a buzz than slower random orbitals.
Dust management is functional rather than sophisticated. The sander has a built-in dust channel that directs particles towards the rear, where a dust bag can be attached. The included collection bag captures a portion of the dust, but for indoor use — especially when sanding between coats of finish in a living space — connecting the dust port to a shop vacuum produces far better results. The pad itself has a series of holes that allow dust to pass through, and the matching hole pattern in the sandpaper is important for effective extraction. Pre-punched 1/3-sheet sandpaper with the correct hole pattern is readily available from multiple brands including Makita's own abrasive range.
The BO4566 measures approximately 100 by 164 millimetres in pad size with a body that fits comfortably in one hand, and it weighs a manageable 1.2 kilograms. Makita manufactures the tool in Japan and backs it with their standard warranty. Customer feedback is solid at 4.4 out of 5 stars from nearly 900 reviews, and it ranks number 49 in the Sheet Sanders category — a respectable position in a category dominated by budget options. For woodworkers and finishers who appreciate the simplicity, reliability, and fine-surface quality that only a dedicated sheet sander can provide, the BO4566 represents excellent value from a brand known for tools that last.
Pros and cons
Pros
- Ultra-lightweight at just 1.2 kg — comfortable for extended one-handed use on vertical surfaces and overhead without fatigue, perfect for long finishing sessions
- Rectangular 100 x 164 mm pad reaches into corners and along edges — areas where round random orbital sanders leave unsanded crescents
- Standard 1/3-sheet format uses inexpensive, widely available sandpaper — cut your own from full sheets or buy pre-cut packs at any hardware store
- Spring-loaded metal clamps hold paper absolutely secure — no adhesive or hook-and-loop to wear out, and the paper cannot shift or peel during use
- 14,000 OPM high-speed orbital action produces a fine, uniform scratch pattern ideal for between-coat sanding and final surface preparation
- Makita build quality and Japanese manufacturing — a proven, reliable tool backed by nearly 900 reviews averaging 4.4 out of 5 stars
- Simple single-speed operation — no settings to adjust, no learning curve, just turn it on and achieve consistent results
Cons
- Single fixed speed of 14,000 OPM — no variable speed control means you cannot slow the sander down for delicate veneer work or particularly soft timbers
- Sheet sanders are inherently slower at material removal than random orbital sanders — not the tool for stripping heavy paint or levelling large filler patches
- Paper clamping system, while secure, is slower to change than hook-and-loop — swapping grits between sanding stages takes a few extra seconds each time
- Dust collection is basic — the included bag captures only a portion of fine dust, and connecting to a vacuum is almost essential for indoor finishing work
- Corded design means you are tethered to a power socket — less convenient for outdoor or multi-room projects than a cordless alternative
Use cases
The Makita BO4566 1/3-sheet finishing sander is ideal for woodworkers, furniture restorers, and painters who need a lightweight, precise finishing tool for between-coat sanding, fine surface preparation, and working into corners and edges where random orbital sanders cannot reach.
Between-Coat Sanding on Paint and Varnish
The most important use for a finishing sheet sander is lightly sanding between coats of paint, varnish, or lacquer. The rectangular pad glides flat over the surface, removing dust nibs and creating a mechanical key for the next coat without cutting through. The 1.2 kg weight lets you work gently with minimal downward pressure — exactly what delicate between-coat work demands.
Fine Woodworking Final Surface Preparation
Before applying oil, wax, or film finishes to furniture and cabinetry, the final sanding pass determines how the finish will look and feel. The BO4566's linear orbital scratch pattern produces a more uniform surface than a random orbital — no pigtail marks — and the 14,000 OPM speed with fine 320 or 400-grit paper leaves timber silky-smooth and ready for finishing.
Corner and Edge Sanding
Inside cabinet corners, along skirting board tops, around door panel mouldings, and up against window frames — these are the areas where a round sander pad is useless. The BO4566's rectangular pad and square front edge reach right into internal corners and sand flush along straight edges, giving you complete coverage that random orbitals cannot achieve.
Delicate Veneer and Thin Material Sanding
Sanding veneered plywood, thin laminates, and delicate inlays requires a light touch — too aggressive a tool and you will sand straight through. The BO4566's flat pad, light weight, and less aggressive orbital action give you the control to smooth veneered surfaces evenly without burning through the thin face layer, making it essential for veneer work.
Drywall Joint Compound Smoothing
After taping and filling plasterboard joints, a sheet sander with fine-grit paper levels and feathers the dried compound smoothly. The rectangular pad covers joint lines evenly, and the light weight means you can work overhead on ceilings without arm fatigue. Connect to a vacuum for near-dust-free indoor operation during renovation projects.
