Is it just me, or do some of the mech.heads on the market this year seem TOO small ??.I mean, I know too large a cutting dia. can be a bad thing, but these 2 blade, 1 and 1/8" cut,,well they have to be almost too " punny" .You had better put that head with in an inch of perfect, because they don' t leave any extra cut, for error !!.[]

some are pretty small, but they will work much better for those wanting mechanical accuracy but don' t really have alot of KE to spare. The Rocket Nail Driver comes to mind.
