Right Angle Grinder
What does it do?
I have a book showing it used to abrade the high spots on a concrete surface; how does this use compare to an orbital sander? Thanks |

Orbital sander is good for finishing wood. Angle grinder can be used to sand heavy rust, cut steel, grind a weld smooth. It is much more heavy duty. |

Agreed, an angle grinder is more agressive.
And when you consider the number of attachments you can get for it it is a very useful tool to have around. Do like me and buy both. |

They are two tools with different uses.
A right angle grinder with a diamond cup doesn't even come close to a orbital sander with even the best sandpaper on concrete. "Greg Esres" wrote in message ups.com... What does it do?

Steve I'm not sure I want to do anything. :-) I need to roughen up a concrete floor a bit and the books show a right angle grinder being used to grind down some high spots. I have not yet established that there *are* any high spots, so a regular sanding block is probably all I need in the short term. |

Useful if you want to knock down high spots, grout, or if you want to knock off cool decking. Maybe you want to take off the shine from polishing so epoxy paint would stick better. Then use an orbital with coarse grit, or you could use sanding discs on an angle grinder, but it may leave visible marks after painting. Or, you could use a knot brush, either a flat "stringer" type, or "cup knot brush." If you do get one of these, beware. I have used them for twenty five years now, and they deserve a LOT of respect.
