A step bit eliminates that, by drilling in steps - just a 1/16" at a time. Simple.If you have variety of holes to drill of different sizes, you don't have to change bits.Obviously they don't work on thick material.They are pictured with a box (drill index) yet didn't ship with one.
Four stars for lack of a box, while advertising that there is one. At over $50 a set, it would be nice to not have them in a tool box drawer getting banged around.
GREAT BITS.If you haven't used a step bit to drill sheet metal, you have no idea how nice they are. Just count the number of steps, and drill that many.
The bits deserve five (and protection). You know when you're drilling sheet metal and when the drill punches through, the back side of the hole is really ugly and has sharp things (burrs) attached.
Want a 7/16" hole.
The product shows a case, and mine did not come in a case. It is a great set to have, I wish I would have bought this many years sooner.
