Hummmm
In the automotive profession for about 23 years, never heard of an impact
gun, ??? aways refered to as an impact wrench and or air ratchets.

Ratchets aren't impact tools, Leon. And the particular term
"impactor" didn't come about until Bosch coined it for their product,
I don't believe. Other references to the term were astronomical and
the auto industry used "impact", "impact wrench", or "zip gun."



In case you have never seen an impact air ratchet, it is not a new thing but
IR has one that now competes with standare impact wrenches in terms of
torque. Way back when 50~70 ft pounds was not uncommon, now in excess of
200 ft pounds.
