- Electric power.
The electrical power of the electro planer plays a very important role in its selection. Planning a tree requires quite a lot of effort (as mentioned above, it was their savings that became one of the main reasons for the appearance of this tool), so the performance of the planer directly depends on the engine power.
Manual electric wood planers have a power in the range of 0.5 – 2.2 kW.
For example, a Bosch PHO1 electric planer has a power of 0.5 kW, and a Rebir IE wood planer – 5708C – 2.15 kW.
If you sometimes need to plan a couple of boards, you can purchase a model with a power of 0.5-0.6 kW. If you plan to use an electric planer more often and in larger volumes – choose a power of 0.7-0.9 kW.
Electric wood planers with a power of more than 1 kW are already, one might say, professional planers.
- The frequency of rotation of the drum.
The rotating drum, on which the cutting knives are fixed, is the main working element of the electro planer. The frequency of rotation of the drum is the number of revolutions that it makes per unit of time. In fact, the rotational speed indicates how many times the cutting knives come into contact with the surface to be trimmed over a certain time.
In modern planers, the rotational speed can range from 12,000 to 18,000 revolutions per minute. These are quite large indicators.
On the drum, there are mainly two cutting knives, therefore, for example, at a speed of 15,000 rev/min. each of the knives in one minute 15,000 times in contact with the surface. To perform a work similar in scope when using a simple manual planer, we would have to do 30,000 movements. It is for this indicator that you can very clearly compare the performance of a simple and electric planer.
When buying, you can focus on the rotational speed of 15000-16000 rpm.
- The width and depth of planing.
The width of the planing shows how wide the material of the wood planer can handle in a single pass. This indicator is measured in millimeters. Most modern electrical planers have a planing width of 82 or 110 mm.
The greater the width of the planning, the fewer passages you need to make for a complete surface treatment.
The depth of planing shows which layer of wood will be removed with a wood planer when planing. In most cases, it is possible to regulate this indicator from the minimum to maximum value supported by the instrument with a switching step of 0.1 mm.
In less powerful “amateur” tools, the maximum planing depth is up to 2 millimeters; in more powerful ones, this figure can reach a value of 4 mm.
In principle, for consumer needs, a maximum planing depth of 2 mm is sufficient.
- Parameters of the sole.
As I have already said, the sole of the electro planer, together with the knives, is the main contact surface of the tool. The sole must be smooth and even, however, to prevent the appearance of so-called “airbags” there must be special grooves in it. Sometimes these grooves are almost invisible to the naked eye and their presence can be checked only by touch.
- Weight electro planer.
The wood planer is a hand-held tool and its specificity requires the need for rather long manual work with it. Therefore, the weight of the tool significantly affects the productivity of the operator.
The weight of the planer can be from 2.5 to 8 kg. A professional electric planer can weigh 9 kg.
Models with an average power have a weight of 3.2-4 kg, it is on this weight that you can navigate.
Also, it will not be superfluous to pay attention to the convenience of the planer pens. After all, with comfortable ergonomic handles, the weight will be felt much less.
- Advanced options.
In electro planers there may be such additional parameters:
– the presence of a dust collector. Work with an electrical planer forms a large number of shavings and dust, if the tool is equipped with a dust collector, then all this will be collected in it, and not scattered around you.
– the presence of a side stop. A side stop is a device that attaches to the planer and helps to increase its balance and accuracy.
– the presence of depth gauge. This is certainly not a submarine, in our case, the depth gauge helps to determine the depth of planning.
Some models (see these high-quality portable planers for a wood surface) come with a special tool for electrical cutting, which allows you to use an upside-down tool as a mini-machine.
I hope all of the above will help you decide and buy a good manual electric planer.
And in order to find out more precisely how to work with an electric planer – read the instructions carefully, pay special attention to the safety regulations.
