Best Power Drill Bit Sharpeners of 2025

"Having used various drill bit sharpeners, I found the Drill Doctor to be the best. It's easy to set up, especially for larger bits over 1/4 inch. While I had some difficulty with smaller bits, the quality of sharpening is excellent and it's great for garage mechanics."

"This is my third Drill Doctor, and I love the 500x model. After getting used to the setup, it effectively sharpens bits for my work in plastics. I highly recommend using a Sharpie for alignment. Once you learn the settings, it works very well."

"I bought this a few months ago and have sharpened over 50 bits. It does an outstanding job on standard 118° bits, and I've successfully sharpened masonry bits too. However, I struggled a bit with 135° split-point bits, but overall, the machine's quality is impressive."

"I was skeptical at first, but after sharpening several black oxide bits, I found it easy to use. It did a fantastic job restoring the edges. I was truly impressed!"

"I didn't expect such high quality from this sharpener. In just 20 minutes, I was able to sharpen a dozen drill bits, and they looked and felt like new. If you're considering a drill bit sharpener, just go for it!"

"This Drill Doctor sharpener has been a great addition to my workshop. I dulled about ten drill bits on a project, and within 30 minutes, I had them all sharpened. It's user-friendly, and I'm thoroughly pleased with the results!"

"I find it easy to use and it sharpens bits quickly, bringing them back to almost like new. Plus, it's not very loud, about the level of a vacuum cleaner. It's a good value, especially compared to buying multiple large replacement bits."

"Having previously used a $4000 Darex professional drill sharpener, I noticed that the Drill Doctor lacks finer adjustments and has a plastic chuck. While it still does a decent job, I have to eyeball the clocking due to the lack of angle adjustment on the split point relief fingers, which can affect the accuracy of the split point geometry."

"Initially, I thought it seemed a bit expensive, but after sharpening a lot of drill bits over the holidays, I found that it works great once you get the hang of it. I've ended up saving a significant amount of money by sharpening bits that would otherwise cost me $80 to replace!"

"I found that this sharpener works great! It took a bit to align the cutting edge correctly, but once I got the hang of it, I could sharpen my bits quickly. I mounted it with an M-12 bolt and wing nut, and it fits perfectly after a little filing. Just ensure your mount is solid!"

"After watching a helpful video review, I decided to try the GENERAL Tools Drill Bit sharpener. I've used it around 16 times so far, primarily on 1/8" bits, and it has performed flawlessly. If you come across negative reviews, I think they're mistaken. Amazon's return policy makes it easy to replace if needed!"

"Setting mine up next to my grinding wheel was straightforward. It doesn't come with much guidance, but if you're familiar with drill bit sharpeners, you'll figure it out. I managed to sharpen about 10 bits from small to around 5/8”, and it worked exceptionally well!"

"I found that it doesn't sharpen smaller bits well at all, but I haven't tried it on larger bits yet. I'll update my review later."

"This sharpener has been great at keeping my old drill bits sharp for as long as possible! I highly recommend it!"

"Honestly, when I first unboxed it, the product felt a bit cheap, but it does manage to sharpen my bits nicely. If you only plan to sharpen a few bits here and there, it's a handy tool to have in your toolbox."

"I got so tired of dull bits breaking. Sharpness is essential! The bit sharpener has saved me so much time, and I’ve stopped buying new bits. The only issue is that smaller bits don't line up perfectly, which requires a little adjustment from the exposed end. I regret not getting this sharpener sooner!"

"After an hour sharpening my bits, I was frustrated when they didn't work on metal. The Drill Doctor website mentions this model sharpens at a 118-degree angle, which is great for wood but not for metal. However, I realized my mistake was not applying enough pressure while sharpening. Now my bits work perfectly after a few adjustments!"

"This product did an incredible job on my dull bits! It's incredibly easy to use. I also saved money by not having to buy new drill bits."

“I took a chance on this sharpener, and it works perfectly and better than expensive machines. Thank you!”

“So far, my sharpener is performing well. I’ve used it for a few small drill bits, and it puts a nice edge on them. Figuring out how to hold the drill bit at the right angle was a bit tricky, but using the edge of a table helped. For the price, it’s a handy tool to have.”

“This bit sharpener is great! I used it to sharpen several of my drill bits, and it worked wonderfully. My carpenter friend was also impressed and mentioned he’d be ordering one himself.”

"I should have gotten this a long time ago. It costs about the same as 3 or 4 drill bits, and now I can sharpen my drill bits on the fly. Great deal!"

"I was surprised at how simple this was to use. I just found the right hole for my bit, pushed it in, and twisted until it started to grind. The bits I sharpened now cut cleaner and go in easier. Sure, there are better sharpeners out there, but this one works fine for me."

"Honestly, I thought drill bit sharpening was an art form. However, my super dull drill bits came back to life after using this sharpener. It’s quiet, has minimal vibration, and I love that I can easily access the power switch. The bits feel brand new for now!"

"I absolutely love the high-quality materials used in this product. It feels durable and well-made!"

"Using it is a breeze, and I appreciate the stylish design that fits my aesthetic perfectly."

"For the price, it’s an incredible deal. I feel I got great value for my money!"
