DEWALT Cobalt Alloy Steel Drill Bit Set with Pilot Point, 14-Piece (DWA1240)

I occasionally need to drill some holes in metal to make restoration parts for antiques. Like a custom bracket here, a hidden bracing piece there. Try it with regular drill bits, the kind that come with a drill or with a "1000 tools in a 10 inch box" kind of thing. Forget it, they turn to mush, they're not meant for metal even if they say so on them. I made some messes and started some cutting oil fires, that kind of thing. So I asked a friend who works on fancy doors what he does for all the holes he has to drill in things that are metal. So what I found out is use "Cobalt" (still contains steel) bits, press really hard, and put the drill on really low speed. I knew I didn't want to pay $$$ for whatever he uses in his pro work. He admitted his bits are so precious they come packed individually. How to do this but only occasionally? So having been very pleased with Dewalt stuff in the past (my hand drill and job site saw are from them for example), I decided that a small multi-pack from a reputable brand like this would be a good bet. It was. These drill through metal sheeting with my plain 15 year old Dewalt hand drill. We're talking like millimeters in my case. So I do not know what would happen if you tried it on a hunk of railroad rail or something like that. I drill things like an extra hole in things about as thick as a shelf bracket or less. Makes a clean round hole. Punch first, then push hard and drill slowly, right into some backing material like cheap pine scraps, and a few swipes with say 150 grit sandpaper to make sure there are no burrs and you're set. So for a relatively low price, I got the result I wanted. And it's real Dewalt, so you're not just punting, yet it costs about the same as random cheap sets on here. Importantly, the benefits of it occurred to an amateur like myself, who doesn't drill metal regularly but needs it to work when he needs it.

I usually burn thru bit sets pretty quick but these have stayed sharp and unbroken for almost a year now. Use them on metal wood plastics and everything in between and are still going strong

Had zero issues with these bits. Cut through 1/4 inch steel angle iron with ZERO problems. I used these on a power drill. I was skeptical about these bits. These bits were recommended by Project Farm on YouTube.

I have used many different kinds of wood, metal and masonry drill bits over the years. Some are good, some are absolutely horrible (start burning almost immediately), and only a few are what I would consider the hammer of Thor of type of efficiency. I recently had to bore some holes in a 2x4 for a steel target hook that needed to be fastened to the post with screws/nuts/ washers. When I started the job I began by using these wood- specific IRWIN Marples Woodboring Forstner Drill Bits, and no joke all of those "special" bits I used started smoking nearly immediately. So, I stopped and went back to the garage and grabbed these. I said a quick prayer that these bits can last me through the 2 holes I needed to make, got the Dewalt bit set up and holy God! These Dewalt bits chewed through the wood in less than 2 seconds (multiple holes made). I couldn't believe how fast and powerful these bits were. Maybe I got lucky with these, but man these bits were amazing! Time will tell how long they last for, but for now I'm truly impressed.

I like these DEWALT cobalt drill bits. Used with cutting fluid, they cut well and stay sharp. I was able to drill out a broken easy out made of hardened steel — not easy, but these bits handled it without burning up or chipping. I’ll definitely consider getting more of these if I need replacements.

Recently, I bought a 99 Honda CR-V for $500 and had a lot of issues. Anyway, over the weekend, I was working on my car replacing all the suspension (ball joints, control arms, axles, tie rods, struts, etc.) and when I was nearly done, I had one screw to take off the rear lower control arm and it was the one that screws the lower ball joint onto the control. And guess what? It snapped with little to no pressure just to find out that the only thing keeping the bolt from coming was that it was rust welded onto the tack welded but on the other end! (I’m pretty glad I found that out now rather than later while I’m driving). I tried using all the drill bits I had at home and none of them worked. Even the screw extractor kit I bought Autozone didn’t even work, but with this one, it was magical. The fact that I didn’t have to punch the screw before hand was great because not of my punches would actually make an indentation on the darn bolt. But man, I put a bit of cutting oil and started drilling and man. I’ll tell you what. It was drilling through that screw like a hot knife going through butter. After drilling through two inches of Grade 8 bolt, it didn’t even seem to show any wear on the drill (besides metal flakes). This set is absolutely great and will last for years to come! Highly recommend these!

I am astonished! Believe me, I have purchased hundreds of different types and brands of drill bits in my 60 years of woodworking and medal working. These bits are like a hot knife cutting through butter. They are the best of all of my bits collection. Highly recommended.

superb drill bits. will buy again. sharp. better than cone drill set
