Bosch 18V Cordless Planer Review: A Handy Tool for the Shop
Cordless power tools have come a long way, and I'm always happy to eliminate another extension cord from my shop. Besides making tools more convenient to use, battery power means less time setting up and more time getting to work.
The Bosch 18V Brushless Planer is a good example. This compact, battery-powered hand planer makes quick work of trimming doors, fitting windows, fine-tuning project parts, and removing material from rough lumber.
We put it through its paces in the Woodsmith shop, from routine trimming jobs to flattening a large walnut slab. Here's a closer look at its features and performance.
Bosch 18V Cordless Planer: Features and Design
The Bosch planer combines a brushless motor with an 18V battery system in a compact, maneuverable package.
Unlike a stationary thickness planer, this handheld tool is designed to remove material from specific areas of a workpiece. That makes it especially useful for fitting parts, trimming edges, and working with lumber that's too large or awkward to bring to a stationary machine.
Brushless Motor and Reversible Blade
The brushless motor delivers consistent cutting performance, while the single-blade cutterhead keeps blade changes straightforward.
The blade is reversible, allowing you to use the opposite cutting edge when one side becomes dull.
The blade is also easy to replace and align, an important consideration for a tool that's designed to make frequent trimming cuts.
Adjustable Cutting Depth
The planer features a 3-1/4"-wide aluminum sole and an adjustable cutting depth ranging from zero to 3/32".
A large knob at the front of the tool controls the depth of cut.
For light trimming, a shallow setting allows you to remove material gradually. When more stock needs to come off, you can increase the depth and make additional passes.
This flexibility makes the planer useful for both fine adjustments and more aggressive stock removal.
Built-In Chamfering Grooves
The front sole includes three machined V-grooves designed for cutting chamfers.
The grooves accommodate nominal chamfer sizes of 1/8", 1/4", and 3/8", giving you a convenient way to ease or bevel the edges of a workpiece.
It's a useful feature for trim work, exposed edges, and other jobs where a consistent chamfer improves the appearance of a project.
Parallel Guide for Straight Edges and Rabbets
One of the included accessories is a parallel guide that attaches to either side of the planer.
The guide consists of two metal plates held in position with wing nuts. It's a simple design, but it does a good job of helping keep the planer aligned when working along an edge.
The guide is particularly useful for two operations.
Edge planing. The guide provides a reference surface that helps maintain alignment as you plane along the edge of a board.
Cutting rabbets. The guide can also act as a fence to establish the width of a rabbet, making it easier to remove material consistently along the edge of a workpiece.
For a compact handheld tool, this accessory adds a useful amount of versatility.
Dust Collection and Chip Control
Power planers produce a surprising amount of chips, even during relatively light cuts.
Bosch includes a dust bag to help manage the mess.
The dust bag can be installed on either side of the tool. A selector on the planer changes the direction in which chips are discharged.
This is a convenient feature when working close to a wall, cabinet, or other obstruction. It also allows you to direct the chips away from your immediate working area.
For larger jobs, it's worth considering how quickly the bag will fill and whether a compatible dust extraction setup would be more convenient.
How Does the Bosch 18V Cordless Planer Perform?
The real advantage of this planer is how quickly you can put it to work.
Without a power cord to manage, it's easy to grab the tool for a few quick passes on a door, piece of trim, or project component.
The planer performed well during routine trimming operations in our shop. Its compact size made it easy to maneuver, and the adjustable cutting depth provided the control needed for different jobs.
Battery Life for Everyday Trimming
During our testing, battery life was sufficient for several hours of trim work before needing a battery change.
Of course, actual runtime depends on the battery capacity, cutting depth, wood species, and how heavily the tool is being used.
For intermittent trimming jobs, however, the cordless design proved especially convenient.
Flattening a Large Walnut Slab
We also put the planer to work on a much larger project: an approximately 18"-wide, 12'-long black walnut slab.
A single battery provided enough runtime to complete the flattening work.
That's an impressive example of what a compact cordless planer can accomplish, although leveling a large slab still requires careful technique and repeated passes.
A handheld power planer is best used for controlled material removal rather than as a substitute for the precision of a stationary jointer or thickness planer.
Where a Cordless Power Planer Makes Sense
A handheld power planer isn't a replacement for every planing tool in the shop. But it fills a useful role between hand planes and larger stationary machines.
Here are several jobs where this type of tool is especially handy.
Fitting Doors and Windows
A power planer can remove small amounts of material from the edge of a door or window component, making it useful for correcting a tight fit.
Fine-Tuning Trim and Project Parts
When a board or trim piece needs a little material removed, the cordless planer provides a quick alternative to repeated trips to a stationary machine.
Removing Material from Rough Lumber
For large or awkward workpieces, a handheld planer can remove high spots and rough material before further flattening or smoothing.
Cutting Chamfers and Rabbets
The V-grooves and included parallel guide extend the tool's usefulness beyond ordinary surface planing.
Woodsmith Tip: Start with a Light Cut. When using a handheld power planer, start with a shallow cutting depth and make multiple passes rather than trying to remove too much material at once. This gives you more control, helps produce a cleaner surface, and reduces the chance of accidentally removing too much material.
Our Verdict: A Convenient Addition to the Shop
The Bosch 18V Brushless Planer proved to be a capable, convenient tool for the woodworking shop and jobs around the house.
Its brushless motor, adjustable depth control, reversible blade, and included accessories make it useful for a variety of trimming and fitting operations.
The cordless design is a major advantage. Being able to pick up the planer and get to work without managing an extension cord makes small jobs especially convenient.
While I wouldn't choose it as my primary tool for rough framing, it's an excellent option for fitting doors, trimming parts, and handling occasional stock-removal jobs.
For woodworkers who want the convenience of a handheld power planer without the hassle of a cord, the Bosch 18V model is well worth considering.

A power planer is great for removing material quickly, but a traditional hand plane is often the better choice for fine-tuning a surface and producing a glass-smooth finish.
