Which grinder for polishing

[JimM]

Hi all

I've got a couple of bench grinders and want to use one of them for polishing. The grinders are both 6" models but one is rated at 210W and the other 375W - which should I use for polishing and which should be left for grinding.

If it's any help the parts for polishing will only be small items for model engineering and grinding wise it will mainly be lathe tools.


Cheers

Jim

Use the 375 watt for polishing, polishing operations generally take longer than grinding a tool,and will load the motor more with pressure on the mop, so better to have the bigger motor doing the most work.
