2x72 Knife grinder | eBay
May 19, 2019· The Bosch 1994-6 9-Inch Angle grinder is my recommendation for the best concrete cutting, and grinding tool.. CHECK CURRENT PRICE . Best tool to cut steel. Mostly angle grinders can be used to cut all types of metals. With a good cutting wheel installed, angle grinders can cut through steel sheets, reinforcing, and take out sections out of metal rods or bars, and even split bolts and screws.
