Comparison DeWALT DCM565P1 vs DeWALT DCM575X1

The largest tyre size (in chain saws) or disc (in circular saws and some others, see "Device") that is allowed for this tool. Tyres are sized by working length, rims by diameter.

A larger bar/wheel allows for deeper cuts but requires more powerful motors. Therefore, this parameter cannot be exceeded — this can lead to an overload of the engine with all the corresponding troubles. However, in many models with a disc it is physically impossible to install a nozzle with a diameter larger than the maximum allowable.

Also note that saws with similar bar/blade sizes may differ in maximum depth of cut (mostly due to differences in design or power). As for the specific dimensions, they depend on the type of saw (see "Device"). For example, large discs of 450 – 500 mm are found exclusively in stationary chain saws, the maximum figure for cutting models is 400 – 450 mm, for trimming — 300 – 350 mm, and sizes of 500 – 550 mm or more clearly indicate that speech It's about a chainsaw chainsaw bar. Detailed recommendations regarding the choice of a tool for a given size can be found in special sources.

The maximum speed of the chain relative to the material that a saw of the appropriate design can provide (see "Device"). Higher speed allows to achieve faster and cleaner cuts, but requires more engine power; low speed, in turn, reduces productivity, but allows you to achieve good traction with a relatively low engine power. More detailed recommendations regarding this parameter can be found in special sources.

- Disc. The presence of a saw blade is included in the delivery set of the circular tool. It can be either one or several, which allows you to use the saw “out of the box” without the need to purchase additional consumables. If you already have a saw blade or intend to select it for specific tasks, it is worth taking a closer look at the configurations without a blade - they are usually cheaper.

- Chain. One or more chains included as standard with the saw. The presence of a chain with teeth for cutting allows you to do without purchasing a separate executive body for chain saw. However, there are configurations without a chain - it is assumed that the customer already has a chain or he will select the required option himself.

— Saw blade. The presence of one or more saw blades in the complete set of a reciprocating or band tool. They ensure that the saw is ready for use literally immediately after unpacking. There are also configurations of reciprocating or band models without a saw blade - they are cheaper, and the customer has the right to choose a suitable blade independently.

— Dust collector. A dust collector is included with the saw. The dust collector is a container for collecting sawdust and other d...ebris generated during operation; As a rule, such a container is made removable. Installing a dust collector slightly increases the dimensions of the entire tool, but this is compensated by cleanliness and convenience: dust and other production waste mostly settle in the container and not on surrounding objects.

- Charger. The presence of a charging block in the package allows you to charge batteries. Accordingly, for models with batteries, this accessory is necessary to power the battery. However, there are models without a charger. And saw with it may differ in the charger model, the name of which will allow you to learn more about its characteristics and, if necessary or if required (breakdown), purchase a similar one.

— Case (bag). Availability of a case or bag included with the instrument. A case is a container-suitcase made of hard material; bags are usually made of soft material. This way the case provides maximum protection and the bag can be folded away compactly when not in use. The specific type of case that comes with the saw should be specified separately. However, in any case, a complete case or bag will be more convenient for storing and transporting the instrument than impromptu packaging.

- Stand. The stand makes the saw tool more stable, reliable and safe. The presence of a stand is typical for stationary type saw. Mostly these are powerful, productive, large and heavy models that are located in a separate place. The stand can be implemented either with classic legs (bed) or with a cabinet with a tool compartment. The stand can be equipped with various types of saw: circular saw, miter saw, band saw, cutting saw and even chain saw (with electric drive).

— Wheels for transportation. Transport wheels make it easy to move sawing equipment around the shop. The presence of wheels will come in handy when the saw needs to be moved a little to install some large workpieces or simply when cleaning the workshop. As a rule, wheels are typical for stationary saw with a table top or work holder.

The name of the battery platform supported by the device. A single battery platform is used to combine various power tools of the same brand into one line (screwdriver, grinder, circular saw, etc.). Devices on the same platform use interchangeable batteries and chargers. Thanks to this, for example, there is no need to select a battery for each individual model of a power tool, because one purchased as a spare battery can be used in various power tools, depending on the situation or as needed. Batteries of the same platform basically differ from each other except perhaps in capacity.

The operating voltage of the battery in the saw with the appropriate type of power supply (see "Power supply"). The more powerful the tool, the higher the battery voltage, usually. At the same time, this parameter is usually selected in such a way as to optimally match the characteristics of a particular model; therefore, in fact, voltage data may be required only when looking for a spare or additional battery.

Note that most often in modern saws one of two standard voltages is used — 18 V or 36 V. Batteries less than 18 V are typical mainly for compact low-power models, and 40 V or more — for heavy units, mostly professional ones.

Capacity of the battery supplied with the saw of the corresponding type (see “Power source”).

In theory, the higher the capacity, the longer the tool can work without recharging/changing the battery. However, in practice everything is not so simple. Firstly, actual autonomy depends not only on the characteristics of the battery, but also on the power consumption of the tool (and this is directly determined by the engine power). Secondly, only batteries with the same rated voltage can be compared by capacity in ampere-hours; if the voltage is different, ampere-hours must be converted to watt-hours using special formulas and using the results already obtained. So it makes sense to compare this parameter only with saw with the same battery voltage and similar motor power. And to assess the actual autonomy, it is better to pay attention to the specified operating time and/or number of cuts (see below for both).

Note that many models allow operation with batteries of different capacities - it is enough that they are compatible in connectors and operating voltage.

The model of a standard battery allows you to find out its characteristics in more detail, and also helps you understand what devices it is like and which one should be purchased in case of a replacement due to a malfunction or, if necessary, buy another similar one.

Battery models that the saw of the corresponding type is compatible with (see “Power source”). This information will be useful in cases where the battery(ies) must be purchased separately, for example, if the tool does not come with a battery at all, if you need to supplement the original package, or if the existing battery has failed.

The time required to fully (from zero to 100%) charge the battery in the cordless saw (see "Power supply"); this refers to the complete battery and standard charger. The shorter this time, the shorter the breaks will have to be done for recharging; however, higher capacity batteries inevitably take longer to charge than smaller ones. This can be compensated by the use of fast charging technologies, but they, in turn, affect the cost of the tool.
