We hav tested plunge cut saws and name Bosch GKT 55 GCE as best in test. The plunge cut saw has a powerful motor and a great sawing depth, which makes the machine very useful. The cuts are very tidy. Festool TS 55 EBG is also a good purchase, though it is slighty weaker.
We carry out all of our tests ourselves and test all products in real conditions. Plunge cut saws were tested in a cabinet making workshop on a number of different materials and over a long period. Prior to testing, the thickness of the boards was verified with callipers.
The plunge cut saws underwent a number of strength tests. For example, they were used to saw 45-70 mm thick solid hardwoods of different types, such as walnut and elm. We also cut pine boards. Here, the depth was set to the same thickness and then the machines were examined to see how well their scales agreed. All cuts were carried out at maximum plunge depth to stress the machines as much as possible. The plunge cut saws were also tested in terms of how well they perform over time.
Performance: What materials can the plunge cut saws cope with? How smoothly does the machine run through the material? What saw depth can it cope with on different angles? What materials can it cope with at different saw depths?
Result: The cuts are inspected both visually and with a set square. How accurate are they? How well do the machines’ scales agree?
Ease of use: How easy is it to get started with sawing? How easy is it to understand the machine? Is the manual good?
Build quality: What materials have been used? Does the machine rattle and is it noisy, or does it feel stable and durable? What noise level does it emit during use? Does it give off strong vibrations that can be a problem for the user?
Functions and accessories: How versatile is the plunge cut saw? What accessories are included? What guarantee do you get with the machine?
Overall, this leads to an assessment of the plunge cut saw's positive and negative characteristics. These are weighted against the price and the final result reflects the machine’s value for money.
A plunge cut saw is similar to a circular saw, but it's a kind of refined variant for precision sawing. The design makes it ideal for fine, perfectly straight cuts. You don’t need a mitre guide, folding rule or other similar accessories – and you still get a perfectly straight cut. One major advantage of this type of saw is that you can start the cut in the centre of a board. You can also set a maximum saw depth, which means that you don’t need to make the cut right through the board. Examples of use areas are to shorten doors, saw worktops or in cabinet making.
A plunge cut saw primarily consists of a blade, motor and guide rail. Some models can be used as mitre saws, which means that you can create an angled cut. There are also models that are combined circular saws and plunge cut saws.
In our guide further down, you can also read in detail about what you need to consider when you buy a plunge cut saw.
What should you think about when you’re buying a plunge cut saw? Here we list the factors that it’s important to investigate and understand before buying.
The power is an approximate measurement of how strong the plunge cut saw is. The higher the power, the tougher the tasks it can cope with. For example, solid wood under stress is a true strength test for a plunge cut saw, and the greater the power the bigger the chance that it will cope. However, the power rating stated in the specification doesn't give a complete picture of how the plunge cut saw will perform, as there are other factors that affect how powerful the saw is. But the power is a good guideline when you’re looking for a saw.
The saw depth is the same as the cutting depth. The maximum saw depth therefore determines the thickness of the boards that can be sawn completely through. The lower the value in the specification, the thinner the boards the saw can deal with. The saw depth is adjustable, which means that you can set a smaller depth if you don’t want the cut to go right through the board.
If the plunge cut saw can also be used as a mitre saw, the saw depth for this function may also be stated.
Naturally, the blade is at least as important in terms of result as the saw depth and power. Normally one blade is included with the machine, but it’s important to choose the right blade for the task – both on the basis of the material you are going to saw and how fine you want the cut to be.
The speed represents how fast the blade will rotate, and different speeds are more or less suitable for different materials. If the saw is equipped with a function for speed setting, it’s easier for the knowledgeable user to choose themselves how quickly it should rotate.
Many models also have a mitre function so that the user can set the angle of the saw cut.
If you’re going to work indoors with the plunge cut saw and don’t want sawdust all over the room, it should have an effective dust extractor. However, this must be connected to a workshop vacuum cleaner for the desired effect.
For the work environment to be tolerable for both you and anyone around you, it’s important that the plunge cut saw produces as little noise as possible. But you should still always use hearing protectors when working with electric tools.
The smaller vibrations, the better the control you have over the saw and the less risk you run of developing vibration injuries over time.
A long guarantee is preferable, particularly when you are buying a slightly more expensive electric tool. If something breaks, this means that you avoid buying a completely new product. It’s also important that you can easily get hold of spare parts even after the guarantee period has expired.
