Which variable speed grinder out of these? Does higher speed mean better cut? - TilersForums.com

[WDavison]

I'm after a 125mm variable speed grinder. I was going to go for the £150 Metabo at the bottom of the list, because I think the 2000rpm lowest speed would be more useful polishing at least, but it only goes to 7600rpm max. Does that mean a poor cut? Am I better sacrificing the lowest speed possible and going for another on this listwith a higher top rpm?

Got a choice of the following:

Bosch GWX 17-125S £170

• Output power - 1060w
• Idle revolution - 2800 - 11500

Bosch GWX 13-125S £150

• Output power - 700w
• Idle revolution - 2800 - 11500

Metabo WEV 10-125 £117

• Output power - 590w
• Idle revolution - 2800 - 10500

Metabo WEV15-125 £150

• Output power - 940w
• Idle revolution - 2.000 - 7600

I’d say it depends on what the primary use of the grinder is.
Polishing tile edges is one thing, grinding back the odd bit of high screed is completely different, and requires a different machine.

For me it's

MAKITA 9565PCV 125MM ANGLE GRINDER WITH PADDLE SWITCH

No Load Speed: 2,800-11,000rpm

It'll be for cutting tile, drilling and polishing. Everything else will be done with my other grinder.

Is a higher rpm better or not for those tasks?

I have had my one for about 10 years and polish, cut, grind and drill and has never let me down

I'd go with it but not sure how I'd like the paddle over the switched ones I've aways used, I tend to hold the thing over the top of the blade or near it, when shaping bits of tile in my other hand, rather than the bottom of it.
Sounds like a bad habit after typing it.

Can you lock the paddle switch on Julian?

Gone with the Makita, just noticed the Bosch ones will only take their blades, sod that!

What do you mean?
I Have two Bosch 7-115e and they take any 115mm blade or disc.
or 125mm polishing pad with guard removed.
