As a professional in the Industrial and Scientific field I highly recommend this grinder.Through trial and error, I found that it had great power and versatility for a range of projects. The X LOCK feature made switching between discs seamless and quick. The battery life was impressive, allowing me to use it for extended periods without needing to recharge. The only downside was that it was a bit bulky and heavy, but that's to be expected with such a powerful tool. Overall, a great investment for any industrial power tools collection..
