It’s a bit out of step!
This is a great step bit set. It cuts smoothly and I am just a Dewalt die hard user. There is not much to write on because it has one job function. Cut through metal with ease and last.

They do what they supposed to do
These are one of the best bits that i had in my life. Easily going through 20GA and up of sheet metal. Bits are sharp and durable.
