Review on Efficient Air Powered Chamfering: FOLCONROAD Hand Held Deburring Tool by Jeff Drollinger

Looks the same as many other units sold at Revain, this unit wasn't the cheapest nor the best but the reviews averaged 4+ stars so I was confident about buying this manual to buy a pneumatic beveling machine. My device worked out of the box. There were no instructions other than two hex wrenches to set the depth of cut and change the carbide(?) bits. YMMV
