4.0 out of 5 stars great bit - not packaged like the photo, January 13, 2010
This review is from: Irwin Industrial Tools 10502 Unibit 502 Step Drill Bit Set, 3-Piece (Tools & Home Improvement)
GREAT BITS!
If you haven't used a step bit to drill sheet metal, you have no idea how nice they are.

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? A step bit eliminates that, by drilling in steps - just a 1/16" at a time. Want a 7/16" hole? Just count the number of steps, and drill that many. 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. At over $50 a set, it would be nice to not have them in a tool box drawer getting banged around. Four stars for lack of a box, while advertising that there is one. The bits deserve five (and protection).

2.0 out of 5 stars False Advertising, November 16, 2011
This review is from: Irwin Industrial Tools 10502 Unibit 502 Step Drill Bit Set, 3-Piece (Tools & Home Improvement)
If you aren't going to send these bits in the case that is shown then maybe you should advertise differently. I felt ripped off when I received my item and it did not include the case that was shown. Slick.......

5.0 out of 5 stars Irwin 10502 3-Piece General Purpose Unibit Set, May 12, 2007
This review is from: Irwin Industrial Tools 10502 Unibit 502 Step Drill Bit Set, 3-Piece (Tools & Home Improvement)
It is a great set to have, I wish I would have bought this many years sooner. The product shows a case, and mine did not come in a case.
