• ##### 5 Tips to Remember When Using an Angle Grinder on Stone

Never force the blade when using an angle grinder to cut stone. This can result in the blade shattering and kicking up into your face. Guide the blade as best you can, but refrain from pushing down with too much force. You should also always position the angle grinder so the wheel spins away from stone edges and not into them. This will stop
