Disappointing Grinder for Industrial Needs

The power tool did not meet my expectations for its level of quality and durability. Through trial and error, I found that it was not reliable for consistent use in industrial settings. While it may work for simpler projects, it is not sufficient for more demanding jobs.

Pros
  • None that I could find.
Cons
  • Unreliable for industrial and scientific use.

Powerful, smooth and easy to control.

As a savvy homeowner, I value good tools. This angle grinder is worth the money, the CVT is excellent throughout the gear range and the anti-vibration spring in the drive gears really works as advertised. The angled handle is really great and this thing packs a lot of power. Sure, you can go to a discount store and buy an angle grinder for $39, but control is everything when using a tool like this. As a firefighter, I once helped treat a victim whose grinder abandoned him. Not pretty. Don't…

Pros
  • Speed control allows user to adjust speed based on application
Cons
  • Small parts

Overall good with a few drawbacks.

The most positive aspect of this grinder is the lack of vibration. The world as a whole. The most negative aspect of this Makita is the air intakes on the side of the tool, right where the hand would be. These side air intakes allow dirt and debris from hands and gloves to easily enter the grinder. These inlets are very strong. Obviously, this dirt pickup can lead to premature engine failure. Anyone who has ever welded or been around welders knows that their hands, or usually gloves, pick up a…

Pros
  • Powerful 12.0A motor offers more power and adjustable (2800-11000) speed
Cons
  • Some bugs
