The short answer
The Ridgid R4331 handles wider boards slightly better because its maximum capacity is about 12-1/2 inches, compared with 12 inches for the Makita 2012NB. That extra half-inch matters when flattening stair parts, wide shelves, cabinet panels, or glued-up stock.
The Makita is the better choice when portability, lower noise, and a compact footprint matter more than the last bit of capacity. It is also a proven planer with a strong reputation for consistent feeding. For ordinary 4/4 and 5/4 boards under 12 inches wide, the difference is small. For repeated wide-board work, the Ridgid has the practical edge.

Ridgid R4331 vs Makita 2012NB specifications
| Feature | Ridgid R4331 | Makita 2012NB |
|---|---|---|
| Maximum board width | 12-1/2 inches | 12 inches |
| Maximum board thickness | About 6-1/8 inches | About 6-3/32 inches |
| Motor | 13 amps | 15 amps |
| Rated cutterhead speed | About 9,000 RPM | 8,500 RPM |
| Maximum cut | Up to 1/8 inch, depending on width and wood | Up to 1/8 inch, with shallower cuts recommended on wide stock |
| Cutterhead | Three straight knives | Two straight knives |
| Portability | Portable, but bulky | Compact and easy to carry |
Specifications can vary slightly by production year and market, so check the manual for the particular machine you are buying. Neither planer is a replacement for a jointer: a thickness planer makes the top face parallel to the bottom face, but it will not reliably flatten a badly bowed or twisted board without a sled or a previously flattened reference face.
Which one handles wide boards better?
The Ridgid wins on capacity by a narrow margin. Its 12-1/2-inch opening accepts a little more material than the Makita. That can save a rip cut on a panel that is just over 12 inches wide, and it gives you more room when a board has irregular edges.
That does not mean either machine should routinely remove 1/8 inch from a 12-inch-wide hardwood board. Wide cuts load the motor heavily, increase tear-out, and can leave pronounced snipe at the leading and trailing ends. On hard maple, white oak, or similar stock, start with a cut of 1/32 inch or less. Take a second pass rather than forcing the machine through a deep cut.
For boards close to maximum width, support is critical. Use infeed and outfeed tables or long roller stands, keeping them aligned with the planer bed. If the board drops as it exits, the cutterhead can lift the trailing end and create snipe. The same problem occurs at entry when the board is allowed to tip upward.
Cut quality, knives, and snipe
Both machines use disposable straight knives rather than a spiral or helical cutterhead. They can produce a clean surface in straight-grained softwood and hardwood, but grain direction still matters. Reversing grain, knots, figured maple, and glued-up panels can cause tear-out regardless of which planer you choose.
The Ridgid’s three-knife head gives it more cutting edges per revolution than the Makita’s two-knife arrangement. In use, that can help produce a smoother finish at a similar feed rate, although sharp, correctly installed knives matter more than the raw knife count. A nick in one knife leaves a repeating mark across the board, so inspect the knives when you see regular lines or ridges.
The Makita 2012NB is particularly well regarded for controlling snipe when its tables are adjusted correctly. It is not snipe-proof. Long stock, poor support, loose table extensions, and feeding pressure can still produce a noticeable dip. The Ridgid can also deliver good results, but setup and support have a greater effect than brand differences.
Portability, noise, and dust collection
The Makita is the easier planer to move around a shop or transport to a jobsite. Its compact design and comparatively manageable weight make it practical for a one-person setup. The Ridgid is still portable, but it takes more room on a bench and feels less convenient to carry repeatedly.
Neither planer is quiet. Use hearing protection, especially during long sessions. A shop vacuum connected to the dust port is strongly preferable to relying on the included chip bag or open discharge. Planer chips fill a bag quickly, and restricted airflow can lead to clogging or chips being blown back onto the workpiece.
If you need a more convenient portable setup, compare current portable thickness planers by actual width, weight, and replacement-knife cost rather than motor amperage alone.
Value, maintenance, and operating costs
The cheaper machine is fine if your work is mostly pine, construction lumber, and boards under 12 inches wide. For occasional furniture projects, either planer can remove thickness accurately when you take light passes and support the stock properly. Paying extra for the Makita does not automatically eliminate snipe or tear-out.
The Ridgid makes more sense when its extra width prevents you from ripping panels, or when you find it substantially cheaper locally. Before buying a used R4331, check that the depth-adjustment mechanism moves smoothly, the feed rollers are not glazed, and replacement knives are available. Confirm that the cutterhead turns without rough bearings or excessive side play.
With the Makita, inspect the folding tables, elevation mechanism, and knife seating. Feed rollers contaminated with resin can slip, leaving uneven thickness or stalled stock. Clean pitch from the bed and rollers, wax the bed with a suitable non-silicone product, and measure thickness at both ends after setup.
Replacement knives are a consumable expense. If you routinely plane recycled lumber, inspect every board for nails, staples, and embedded grit before it reaches the cutterhead. One hidden fastener can damage multiple knives and leave the machine unusable until they are replaced.
Which planer should you buy?
Choose the Ridgid R4331 if maximum width is the deciding factor, you work with glued-up panels, or you regularly plane boards between 12 and 12-1/2 inches wide. Its advantage is modest but real, and the three-knife cutterhead is useful for general stock preparation.
Choose the Makita 2012NB if you value a smaller machine, easier transport, and a well-established feed and snipe-control design. For most home workshops working with normal-width boards, its 12-inch capacity is enough.
If your projects regularly exceed either machine’s capacity, look at 13-inch thickness planers instead of forcing a nearly full-width cut. A wider planer costs more and takes more space, but it may be cheaper than repeatedly ripping, jointing, and re-gluing panels just to fit a 12-inch opening.
