What speeds do I use for grinding?
5000 to 8000 RPM is most efficient
What about polishing?
1500 to 3500 RPM is best when using diamonds
What type of diamonds
are best to use for concrete?
There are several grades of diamonds. The best (and most expensive) are the best shaped grains and they are also the hardest. The metal or resin bond that holds the diamond in its matrix is critical. A matrix for concrete is usually much harder (and lasts longer) than a matrix for granite or marble.
Price/Performance is most important. Keep in mind that the lowest price is not always the best value.
What size cup wheels
can I use to expose aggregate?
5" or 4" (with 5/8 - 11 threads) wheels are acceptable
that do not exceed 1.5 lb. in weight. Velcro backed 5" wheels
are easier to change. Our floating back up heads will give the most
consistent finish.
Can I use the DS301, DS302, DS602 or DS605 under toe kicks?
Yes! All the machines have a 4" clearance.
Can I polish to the
edge?
By off-setting the discs slightly, you can work directly against
the wall.
