  • Great grinder. Switch could use improvement.
In general, I am very happy with the Makita angle grinder. Seems well built at a good price. The reason I didn't give it five stars is that the switch is awkward. I usually have to fumble with the switch for a bit to get it to turn on and lock in.

  • Works as described
It's a Makita. The one this one is replacing lasted 40+ years.

  • MAKITA'S ARE GREAT
I am rebuilding my 1930 Model A Ford Tudor, and got tired of changing flap discs, wire brushes and cutting wheels all the time. I already have a Makita 4" I have had for 35 years, still going strong! I have been using the new one for several weeks now and love it! This new one seems every bit the grinder as the old one! I have other Makita products and am very happy with them. I think my next one will be the Metal Chop Saw. HOPE THIS HELPS! ... show more

  • Withstands lots of abuse!
I bought this as a replacement for one that failed after 20 years of hard use and abuse. Can't beat that kind of performance.
