I have purchased a cheap Chinese 9" angle grinder to cut some block paving (I wont need it after this project so will sell it on cheap).

Having a really hard time buying an appropriate masonry wheel. Seems 9" is not that common in the US so there are much less choices of wheels, and many are European imports. I can' just go to the box stores and try one out ofr size, I have to order online. Amazon lists loads but the descriptions often dont match the picture which doesn't match what is actually shipped :-(



The angle grinder is for the US market and claims to use 5/8" wheels. 5/8"-11 seems to be the standard hole size in the US. But a lot of wheels are advertised at 7/8" which I think are european.


Trying to research what the sizes really mean.
I see this wheel:
http://www.amazon.com/Bosch-DB963-P..._sbs_hi_3?ie=UTF8&refRID=1Q3YGY8VKPVR5SMP08S0

the picture shows both a 5/8th inch and a 7/8inch measurement. But the description is clearly stating 7/8th inch.



No where online really seems to detail these specifications.
I see this grinder:
https://www.forneyind.com/store/det...12_angle_grinder_with_58-11_spindle_78_arbor/

advertised a 5/8"-11 spindle with a 7/8th inch arbor? Is the spindle size and arbor size different measurements? Will the Bosch wheel linked above likely fit my grinder that says 5/8th"-11 arbor?


From this link:
http://www.garagejournal.com/forum/showthread.php?t=34264
The "standard" 5/8"-11 spindles use 7/8" wheels


Please help with this confusion!
 
Measure the size needed on your disc cutter?
Here in the UK most/not all 9" cutters take a 22mm hole size
Recommend you go for a diamond blade if not too expensive they do not wear down like a `ordinary` disc
 
The Bosch wheel you posted comes with an adaptor (brass ring) so it will be 7/8 but will fit a 5/8 by using the ring.

This is the one I ordered in the, will check it works. Thing Is we have already tried 2 blades that claimed they would fit and didn't. Luckily amazon returns are easy!

Instructions say 5-8th"-11' which we have purchased but 1 disc was too loose, banother one ended up having a thread which fitted but it would hit the guard!
