Evolution Premium Step Drill Bits
Evolution Premium step drill bits are made from high-quality M2AL tool steel and are heat treated to 68RC, giving them more durability during tough applications. Each bit will produce a range of hole sizes in steel up to 1/8 in. thick and the twin-fluted design allows for a smoother cutting action with no pre-drilling necessary. Evolution Premium step drill bits have three chucking flats on the driving shank to ensure no slipping in the chuck. They are offered in several different combinations of holes sizes. Choose the one or ones you prefer for your tool arsenal.
