Questions & Answers
Yes, the DWA1790IR and the 1/4" Impact Driver are compatible.
Yes, it can be used in the same way that butter can be used with stainless steel:
No, there will be no case or bag included.
I've seen large augers that look similar and are supposed to be used to split wood, but they don't seem to work very well. The step drill bits are only used to bore holes in small to large increments. This set is particularly useful for this, as it makes enlarging holes in 1/4-inch steel a breeze.
Selected User Reviews For DEWALT Step Drill Bit, Impact Ready, 1/8-Inch-1/2-Inch (DWA1783IR)
Even my HSS annular hole saws can't compete. On an impact driver, one of four holes was drilled with a bit through 1/4" steel plate. It chewed through the four holes like butter, so we'll see how it holds up.
Get one now. When you make holes in metal, you'll wonder why you've never done it before. When this thing hits you, the chips it throws will make you smile while simultaneously attempting to put out your eyes and burning you. PPE (personal protective equipment) is strongly advised.
On YouTube, there used to be a video of DeWalt Impact Ready step bits drilling through a quarter-inch plate like it was nothing. With a Bosch impact driver, I used one of these to drill through the steel frame of my pickup truck. When I was installing a trailer hitch, I had to drill a couple of large holes. I had done some planning ahead of time Before you use this, make sure you drill the holes according to the installation instructions. It effortlessly cut through all of that. The ease with which it went through astounded me. I've tried drilling frame steel with standard drill bits before, and it's not easy. It will make you say "uncle" because it is so difficult. br> There are two things that would make the set better, at least for me. The sizes are a little difficult to read because they aren't engraved very deeply, and a pouch to store them in would be nice. br> I'm glad I have these and would buy them again without hesitation.
These are something that I use and abuse. I cut sheet metal and steel that was more than an inch thick. For the heavier items, you'll need a lot of oil to keep them warm. You can't go wrong with these three bits for the price. These step bits are just as good as any other step bit I've tried, but they're a lot less expensive. Yesterday, I spent $65 on bits to try to drill through 1" steel, and I only got two holes done. I dug out an old 7/8 dewalt step bit and used it to drill out the remaining 6 holes. It's impressive.
Making 1/2" and 3/4" knock outs, as well as enlarging 1/2" knock outs in steel and PVC boxes and enclosures, has been a breeze with this Dewalt DWA1789IR step drill. It can also drill 3/8" holes in cabinets for low-voltage control wires' small rubber grommets. The bit has a 1/4" hex shank that fits perfectly into my impact driver, making it extremely convenient. My old Greenlee bit was more expensive than this Dewalt bit, and it only worked with a standard drill chuck, which was inconvenient. This Dewalt bit has withstood repeated use and appears to be in good condition. A guide ring has been machined into it to show where to stop drilling for perfect 1/2" KO's. If you're not paying attention or using too much force on the drill, you can easily make an oversized 1/2" KO hole, especially in PVC pull boxes where the material is thicker than the guide rings, but it'll become second nature after a little practice. When you run the bit all the way through, you'll get a perfect 3/4" KO hole. Overall, the bit has served my needs admirably, so I'm pleased with it and will buy it again if the need arises.
After reviewing a number of different brands, Tod from the YouTube channel Project Farm recommended it, so I bought it. br>So far, this thing has proven to be a beast; I used it to enlarge the thermometer hole on my Charbroil grill, and it sliced through the steel lid like butter. The hole went from 3/8 to 7/8 in a matter of seconds, and the bit showed no signs of wear.
In 1/4" steel 4 x 4 posts, I had to drill a number of 7/8" holes. I tried working my way up from small to large cobalt bits, but the results were disappointing. I bought a highly rated 1/4 to 7/8 step bit, and it worked fine, but only after a lot of fiddling with each hole. I bought this set after hearing that these DeWalt step bits had come out on top in a test group. After drilling a 1/4" pilot hole, I used this DeWalt bit to complete the project. It took less than 30 seconds to drill all the way through! The bits are incredible. When it comes to these, you get what you pay for.
Steel is drilled as if it were butter. I'd never seen this bit before, but after using it, I'm convinced it's a must-have for my campervan project. It's well worth the money, and the size is ideal.
- UPDATE: After a half-year and fewer than 30 holes, I've reduced my rating to four stars: br>After drilling the steel bed frame, one step became dull. It's now stuck on that step every time I drill. The rest of the procedure continues to run smoothly. br>Of course, it's still better than cheap junk, but I don't use it very often and don't want to pay another $16 for it.
