the key word there being most, it wont even come close to one of these bad boys https://www.machinemart.co.uk/p/176..._BfDBx3t3le5j97ogyxoCP9MQAvD_BwE&gclsrc=aw.dsHands down best i have used is the 5” Dewalt flex volt xr. Better than most corded ones
flexvolt is easily the best cordless grinder though, milwaukee fsag is 2nd best but you need to spend a fortune on HD batteries as it will overheat even the 9ah standard battery. not a problem with overheating on the dewalt with even the smallest flexvolt batteries.
