The diameter of the mounting hole for which the blade holder in the saw of the corresponding design is designed (see "Device"). In fact, this paragraph indicates the diameter of the axis on which the disk is installed — this size should correspond to the hole in the disk itself.
Note that some models of saws allow the installation of discs with larger holes than indicated in the specifications — when using an adapter sleeve. The main thing is that the own diameter of the disk does not exceed the values \u200b\u200ballowed for this model (see "Tyre / disk diameter"). Popular sizes include
20mm,
25mm and
30mm.
The total weight of the tool. For petrol models (see "Power Source"), usually, dry weight is indicated, excluding fuel.
In general, it makes sense to pay attention to this parameter primarily when choosing a hand tool. At the same time, note that higher power, a more capacious battery or a capacious tank will inevitably affect weight. However, tools with similar characteristics can and do differ markedly in weight. And here it is worth considering that a lighter model will be more comfortable to work with, but weight reduction may affect reliability and/or cost. In addition, a more massive tool is more stable, it is not so prone to jerks under uneven loads. If we talk about specific numbers, then a weight of
3 kg or less is considered very light,
3–5 kg is relatively small,
5–7 kg is medium,
7–10 kg is significant, and some powerful tools (mainly gasoline) weigh and
over 10 kg.
As for stationary saws, weight is of secondary importance for them — it mainly affects the ease of transportation.
