DEWALT Step Drill Bit, Impact Ready, 1/8-Inch-1/2-Inch (DWA1783IR)

Drill bit was recommended by vendor I purchased the accessory I was mounting. Used it to drill 6 holes through a heavy steel loader bucket on a tractor. The smallest step took a bit to punch through at the recommended slow speed setting, but once that tip made it through, the next steps on the bit went quick and easy with nice clean holes at the finish. I didn’t need a file to clean up any edges as I often do when drilling steel. Great drill bit.

The media could not be loaded. I don't know what it's made of, but it is hard and sharp. Goes through structural steel so much better and faster than other drill bits that are supposed to be good. I haven't tried it on stainless steel yet, but the holes it drills into structural steel are comparable to how good individual M35 bits perform on structural steel, and since those same M35 bits will go through stainless, then I'm confident this Dewalt step bit will go through stainless steel just as well. I will have an opportunity to test it on stainless steel in about a week from now and can give an update afterwards.Update: I picked up 2 other step bits, one Oxmul M35 (5% cobalt) and one Stroton (6% cobalt). The Dewalt similarly outperformed those as well. I drilled stainless steel with the Dewalt and got a surprise---it quickly accelerated in expanding/drilling out the hole once a pilot hole was created. All drilling was done with moderate even pressure at relatively slow speed.

The slow taper makes it easier to get the hole size you want, and makes it possible in thicker material. Can also use to grind out a slotted shape, if needed. Cuts very fast.

I began my project using bits from a local hardware discount store (Warrior brand) on sale for $8.99: drilled the first hole okay though I had to drill a pilot hole to get it started; then it got dull quickly and I struggled to do a couple more holes in my new fire pit ring. Watched a You Tube review of the Dewalt bits that showed it beating all other brands so I forked out the 5x cost to try it. Total "game changer"! The 3/16" starter step eliminated the pilot hole drilling other brands seem to require. This Dewalt bit cut through the steel like butter. I drilled a total of 56ea, 9/16" holes and the last hole cut just as easy as the first with no apparent dulling. Will never buy another drill bit brand; I'm completely sold. BTW, I also used an impact driver instead of your standard drill. Performed beautifully together!

Dewalt products are hard to beat. This step-drill is used in the assembly of smokeless burn barrels. Works great.

I went through the harbor freight step bits so quick it was unreal. So I got this as a hopeful upgrade to get through stainless steel. I ran cold water on it through the entire cut, and it wasn't an easy process but eventually I got through. While the stainless steel seemed to cut the bit just as much as the bit cut the stainless, it did the job. I would buy this bit again for anything else. Stainless steel is a beast on its own. Hate that I only got one good use out of it.

This is the one you want. Sure it's more expensive, but worth every penny. I got tired of the cheaper "impact rated" step bits breaking before I got any use from them, or they would dull very quickly.Tip: Slow rpm's down and use oil. I work with 3/16 to 1/4" thick mild steel plate and angle iron mostly, and hole diameters of 3/8 and 1/2". Pre-drill with a small bit (maybe 7/32") and step up. These will last.

I purchased this after seeing it out-perform most others on a project farm review. It looks great but I've only used it on plastic boxes so far. I'll update if it doesn't last.

Sharp, accurate, durable. Best step drills I’ve used and I’ve used a lot

Los uso para perforar perfiles de herrería y corta como mantequilla y luego las brocas son muy livianas a comparación de otras que e comprado excelente producto

This bit eats thru heavy gauge steel studs pretty well. I borrowed one on a job site from somebody else, and it worked nicely. Catch this bit on sale, it’s worth every penny.

Nice quality

Bought after a cheaper set I bought failed to do the job. I balked a bit at he cost but it really does a good job.
