The DWA1790IR three-bit set with stepped measurements (view larger).

With this three-piece set of impact-ready step drill bits from DEWALT (model DWA1790IR), you’ll get the job done more efficiently with less reactionary torque — in less time. They’re optimized for your DEWALT impact driver with its 1/4-inch hex shank, but they also deliver strong performance every time in rotary drill drivers.

The advanced double spiral flute design outperforms straight flute design and extends the life of the bit. The split point tip increases speed, and they also include laser-engraved measurements to increase step visibility. This package includes a 1/8- to 1/2-inch bit, a 3/16- to 1/2-inch bit, and a 3/16- to 7/8-inch bit.

Among the wide variety of applications these bits can be used for, they’re ideal for drilling into cans, panels, and junction boxes for electricians; enlarging holes in ducts for HVAC applications; and enlarging door hardware for carpenters.

    This review is from: DEWALT DWA1790IR 3-Piece IMPACT READY Step Drill Bit Set (Tools & Home Improvement)
    I am an Iron worker and I use these daily. I use and abuse these. I cut sheet metal and steel over 1 inch thick. For the heavier stuff you will need so oil for the heat. For the price of these three bits you can not go wrong. These work just as good as any other step bit I have tried but the are far cheaper. Yesterday I went through to $65 dollar bits trying to go through 1" steel, I got two holes done. I pulled out an old 7/8 dewalt step bit and drilled out the other 6 hole with the same bit. Impressive.

    I have only had these about 2 months but I really like them. I'm a commercial Electrician and I use them almost daily. This new spiral design cuts really well. I have not noticed any decline in the cutting at all. Lube them like you should for any tool cutting metal and the will last.

    Years and years and years of using twist bits to drill holes in thin-to-heavy sheet metal. I'll never go back! No bit hanging up in the metal, no twisting bones out of place in my wrist, nice clean holes. Much faster than twist bits. Love 'em.
