Square Insert Bit #0 x 1"
Industrial Bit 1/4" Hex
Very nice and not final yet will examine further.
Prefer Felo bits over all others
I'm not sure why Felo is relatively underground. Their bits, screwdrivers, and even ratchets/sockets are as good as any others. Pairs well with Felo's Star bit holder...
Felo make good bits. They are as good as any other bit on the market and better than most.
