Max. speed
The highest spindle speed provided by the router motor. Measured in revolutions per minute. For models that do not have speed control (see "Functions"), this paragraph indicates the standard number of revolutions.
For different work, the optimal speed of rotation of the spindle (and, accordingly, the cutter) will also be different. For example, hard materials like stone require fast rotation, but wood does not; some types of nozzles work better at high speeds, others at low speeds, etc. Detailed recommendations for each specific case can be found in special sources. When choosing, it is worth paying attention not so much to the maximum rotation speed as to the general range of speeds - how much it corresponds to the planned tasks. We only note that in models with a large allowable cutter diameter (see below), the maximum rotation speed can be relatively low - the working edge of a large cutter moves quickly even at low speeds, and for effective acceleration of such a nozzle, too much power would be needed.
Power cord length
The length of the power cord provided in the design of the router.
The long cord, on the one hand, allows the tool to easily “reach” quite remote sockets, provides additional freedom of action and eliminates the need to switch to another socket once again. On the other hand, it can be inconvenient if the power source is not far away and the excess cord has to be stored on the floor, chair, etc.; and with insufficient length, it is quite possible to use an extension cord. Therefore, in most modern routers, the length of the cord is about 2 – 4 m — this is quite enough to reach the outlet in most cases, and at the same time not so much that there is inconvenience due to the large excess.
