What RPM should I use? />

What is RPM, and does it matter?

RPM stands for rotations per minute, which is quite self-explanatory; it’s how many times the blade completes an entire rotation per minute. It all boils down to how fast the blade is spinning, and typically you’d assume that the higher the RPM, then the faster and more efficient your cut is. This isn’t always true, and it all depends on what material you’re cutting and what the diameter of your blade is.

The below table is a rough guide of the recommended RPM, and the maximum based on the diameter of the blade. It doesn’t take into account the material you are cutting, so don’t read the table as if its gospel. Every blade we sell on our website has a recommended RPM on the packaging, so please check that before using.
