This review is from: Irwin Industrial Tools 10228 Unibit 228 Step Drill Bit Set 4-Piece (Tools & Home Improvement)
I haven't used these in ferrous metals, but they are indispensable for drilling and countersinking in brass and aluminum. Twist drills often grab in softer metals, leaving an out-of-round hole. These bits drill smoothly and accurately, and countersinking is a simple operation, too. Highly recommended for brass and aluminum fabrication.

I have used the #3 to enlarge 15 holes in a 1mm thick carbon steel box.
I didn't know if it would stand for that job but it was amazing how easily it cut the steel. No scratches on the bit, excellent finishing. If you need it, don't hesitate to have yours.

no longer worth buying.,
By Barthbill (lowse ahnhaylayse) - See all my reviews
This review is from: Irwin Industrial Tools 10228 Unibit 228 Step Drill Bit Set 4-Piece (Tools & Home Improvement)
I have used these for years, but the current production is of inferior steel. Very soft and does not cut well at all. Suitable only for soft metals. Irwin seems to have outsourced the production to the lowest bidder.
