Terminology: Orbital throw

[tm_ag]

I've read that orbital throw is the measurement of the side-to-side movement of the buffing pad. How will this effect your polishing results? For example, the Festool Rotex 125 has a sanding stroke of 3,7mm vs the Rotex 150's stroke 5mm.

The pad throw is the diameter of the orbit circle.

I think that the smaller the orbit the finer the finish, but i am not sure, anyone?

I have always being told that 5mm is the ideal orbit for detailing.

[Thejoyofdriving]

i guess i made a good choice with the festool than.

Yep, smaller orbit usually mean higher speeds which are beneficial to polish breakdown, heat generation and overall finishing ability.

davet, yes, 5 mm is a healthy compromise between effectivity vs. finish.
