Facom
ENS Slotted Impact Bit......for use with 5/16" Bit
Holders (preferably engineered for use with air or
cordless impact drivers). These are considered
"consumable" items which should be replaced when worn
to avoid damaging fasteners. See cut-sheet photo for dimensions
and details. Open stock item. (Note- I've taken some actual photos as the file pic from Facom looks a bit different.)
