Best Long Drill Bits of 2025

"I found the drill bit exactly as pictured when it arrived. I used it with my DEWALT drill, and it fit perfectly without any issues. Originally, I was concerned about the round shape of the end, but it worked just fine. I needed it to expand a small hole for my studio strobe, and it performed very well, cutting through hard plastic quickly. Now, my umbrellas fit perfectly, and the drill bit is still in great condition after use."

"For a special project, I needed a 1-inch drill bit and decided to buy this one. It has proven to be very durable and easy to use. Thanks to its size and reduced shank, my project was completed successfully, and I couldn't be happier with my choice!"

"I originally bought a comparable Drill America bit to drill through 1/4" steel plate but had a miserable experience with it. Switching to the DeWalt bit was a big time saver; it worked incredibly well, and I'm very pleased with the results."

"I needed to use 5” fasteners to join 2 2x4s on my fence frame. I initially tried without a pilot hole, which was a disaster. I ended up using an angle grinder to separate the boards after rounding off the fastener. After watching a YouTube tutorial, I drilled a pilot hole slightly larger than the screw through the first board and only partially into the second board. This method worked perfectly! The SALI 3/16 x 12” cobalt extension drill bit performed flawlessly. It never stalled or slowed down, and it's still sharp after five uses. I'm thrilled to have added these to my DIY toolkit!"

"I bought the 3/16 in x 12 in HSS black oxide bits to make installing yard signs easier. The ground can be incredibly hard, making it impossible to push the wire frames in without bending them. With this 12-inch bit, drilling deep holes for the frames became effortless. I was able to recruit four helpers and set up multiple signs in one weekend, thanks to the reusable plastic packaging. This bit has made my job so much easier!"

"I've been using drill bits for nearly five decades, so I know when a tool isn’t up to par. Unfortunately, the SALI 3/32” x 6” drill bits were a major disappointment. They struggled to cut through a simple piece of pine and required excessive pressure. I had to frequently pull the bit out to clear the flutes, which halted my progress. The bits did handle some plastics well, but they were ineffective on sheet metal. I wouldn't recommend these bits as they seem to be of poor quality compared to other options on the market."

"I found the 3/32 Inch x 12 Inch bit to be a great deal. Even though I ordered a different size, it still got the job done without any complaints."

"These 6-inch, 5/32" bits were just what I needed for a tight spot. They allowed me to drill all the way through the wood without any hassle."

"After using this bit four times, I can say it seems durable. No warping, and it came in a sturdy plastic case that I appreciate."

“I needed a specialty bit for my project, and this was exactly what I needed. It worked as designed.”

“I bought several sizes of HSS drill bits at once. An extra long drill bit is rare, but when you need one, this is the solution!”

“This bit is great for my woodworking projects if I use it slowly. Perfect for small tasks.”

"I couldn't find these locally in this size. Glad I found them! They're good quality and have remained sharp after much use."

"I specially ordered these for installing downspouts on my gutter system. These bits went through two layers of stamped 22 GA steel and 1/2 plate steel. They saved the day for drilling pilot holes for grade 3 stainless steel tech screws!"

"I bought this drill for a specific project and considered its price in my repair costs. It's well-finished, sharp for wood, and comes in a reusable case that keeps it from getting dull. Most importantly, it didn’t bend while I used it."

"I bought this for a specific job and it worked well. High quality and sharp. A good purchase!"

"Someone had replaced the factory front sight on my 617. I used this to drill the hole for the new sight. It worked well!"

"This is a fantastic product, just as described and works as it should. I'm glad I bought it and will shop here again."

“I found this drill bit perfect for drilling through 4x and 2x lumber while building a play set. It worked flawlessly and showed no wear after drilling over 50 bolts.”

“This product has been great for my needs. I’ve managed to use the same drill bit for 500 feet of field fencing with multiple gates, and it’s still sharp enough for more work.”

“I’m pleased with my purchase. I used it to drill a hole through a wooden door frame for a doorbell installation, and it performed exceptionally well with my Craftsman power tool.”

"I found this drill bit perfect for drilling out the air tube on my Daisy Red Ryder. Starting with smaller drills, I gradually increased the size, resulting in a 35fps increase in velocity. After some modifications, I achieved 310-320fps. Great for basically free mods!"

"I needed a 6” bit that I couldn’t find in local hardware stores, and was thrilled to discover this one on Amazon at a reasonable price. It seems to be of good quality too!"

"I really like how these 7/64" drill bits are long enough to drill pilot holes for my 3" #8 deck screws. They worked efficiently in soft wood, drilling over 100 pilot holes without breaking. For the price, I highly recommend them!"

"I was surprised when the first bit broke after just 8 holes."

"The second bit didn't last either, breaking on the first hole. Unreal!"

"I used these bits to mount a garden hose hanger to brick. They worked fine for that single use, but I probably won’t need them again for years. They still look brand new!"

"I purchased these for drilling holes for tapcons in concrete and brick. So far, they've performed excellently with my Milwaukee hammer drill. I've drilled dozens of holes, and I’m still using the first bit. Definitely worth the investment!"

"I wanted to install handmade shelves in my stone basement. I went through 10 bits to drill 93 holes across various materials, and they held up decently. The bits went through cinder block easily, but I can see they might wear out quickly with heavy use."
