Northern Industrial Step Drill Bits - 5-Pc. Set
this bit set is amazing I would recommend this to anybody who does a lot of steel drilling also that it replaces over a 100 drill bit. I kept on snapping bits and replacing bits over and over until I found these now I don't have to worry about replacing bits and looking for the right bits again. Another thing that was great was I had a coupon for it so I got it for half the price.

i find them very usefull but the most often used are the 1/2 inch and the 3/4 inch they tend to burn out quickley and resharping is a major question? but i use them often instead of changing bits all the time i use them more then my speed changer system whitch has expensive bits

5 piece Step Drill set
Having been bitten by cheap tools in the past, I was skeptical of the quality of these drills. After talking with an NT sales associate and learning of the 1 year warranty, I decided to give them a try. I am pleased to say that these drills are fantastic and I now use them in lieu of an entire index full of regular twist drills. The sharpness is amazing and these drills cut through mild steel like butter. After having drilled at least a couple of dozen holes all the way up to 3/4" in 16 ga steel, I can't tell any difference in the sharpness. In fact, the nitride coating is not even visibly worn yet. Highly recommended, especially for sheet metal work.

step drill bits
These bits are the best. They are as handy as a shirt on a pocket. You always have the right size and they cut light high dollar bits.

Northern Industrial Step Drill Bit Set — 5-Pc
These are great addition to anyones tool inventory! I don't know why I didn't invest in a set earlier! They work perfectly and are extremely clean cutting. They made short work of my task of drilling numerous large holes in sheet metal.

It is nice to have all the different hole sizes available. This is a set of bits that any workshop should have available.

This is a good set to have around for those projects that ordinary bits just can't cut it.

Step Drill Set
This is a great set for the price.
I mainly use it on metal studs in place of knockouts.
I recommend this set for anyone.
Only wish the larger bit went up to 1 1/2 inch.
Smaller bits cuts easily and smoothly.
The larger bit will make you have a good grip on the drill as it works up to the largest size hole.
I have used all the bit on up to 10 gage plate steel - but will bite in and you need a drill that will take the load.
On thicker stock, the pilot hole may take a little longer but once past that point the other diameters go quickly.
