Joe Due Blades & Equipment offering concrete cutting tools, dustless prep tools, tile preparation blades, tuck point equipment & more!

For using our Dust avenger 005 and Dust mizer 005 Kits YES you can use a blade up to 5" diameter because the shroud is designed to allow enough clearance for it.

If you are using the factory metal blade guard then only the blade diameter the grinder is rated for can be used. 

An Angle grinders inch rating is based upon the amps (power) it has and RPM it turns.  5" and 6" angle grinders will run at a lower RPM so the OD blade speed remains at acceptable levels.  5" and 6" grinders typically have higher power rating to compensate for the more energy to turn a bigger blade and also for cutting deeper etc.  

Because of the stress a grinding cupwheel and deep/ wide cutting saw blades put on the grinders-  we recommend and sell the lower rpm (higher torque) and higher amp (more powerful) grinders as they perform better and longer for contrators applications. 

YES

We consider 7"-9" Grinders the same.  You can only run up to a 7" diameter blade with the dust shroud kits

For our Dust avenger 007 and Dust mizer 007 Kits YES you can use a 7" or 9" grinder

An Angle grinders inch rating is based upon the amps (power) it has and RPM it turns.  7" angle grinders will run at a higher RPM (say 8500) than 9" (say 6600) so the OD blade speed remains at acceptable levels.  9" grinders typically have higher power rating to compensate for the more energy to turn a bigger blade and also for cutting deeper etc.  when using a 7" diameter blade/ cupwheel they will have more torque to turn th smaller blade which is good.
