115/125

[hotponyshoes]

Both my Bosch, (115 & 125), are rated at the same speed.

My bosch 115mm & 125mm are 11000rpm and 9000 rpm respectively

I have both 4.5 & 5" grinders & both get used. My 5" metabo ones have a larger motor & body and are my goto for heavy grinding & sanding, though they need to be used 2 handed.
The 4.5's are for lighter use, some of them will take a 5" disc & can be used one handed due to their slimmer body.

Can I just warn people about spending money on Womble grinders, made in Wimbledon I believe.
They either under ground or over ground.
