Review: This could be a one word review..... WOW! - I have never, and I mean never, been able to sharpen a drill bit free hand. Never. Any drill bit that I sharpen by hand that ends up cutting better is an accident. I've looked at drill sharpeners for decades, (really, not exaggerating) but had no interest. My dad had one of those things that you are supposed to use with a bench grinder, but it stat in a drawer and never got used by him, or the guy he got it from. I looked at the consumer units, but I couldn't get past the $160 price, and a name that made me think of one of the UHF TV station ads from Ronko back in the 70s. (wait, there's more!) But with the problem I had with a repair for a client last week caused by dull drill bits, I decided that I needed to buy one. The time lost because I scrapped out making a part cost me more than this thing did. Sure, I can buy a new cobalt drill index for under $150, but then I end up with the same bunch of dull bits in the same sizes in short order. Acrylic and materials like PEEK are surprisingly abrasive and can dull a bit very quickly. This thing is worth every penny. It works, perfectly, and I can use it any time so my drill bits can always be sharp when I need them. Keeping in mind the old adage that "Those who design things to be foolproof fail to take into account the ingenuity of fools," this thing is as close to foolproof as you get. New glasses will help with reading the small numbers on the collets, but you really are going to pick the one that fits the drill. The web diameter adjustment you make is in mm, so a small digital caliper is a good idea. Read the drill size in mm, and set the knob, set the drill bit in the collet, and off you go. The drill bit is held firmly in the chuck and collet. Once the bit is in place, it's held firmly so that there is no guessing for either the first cut, or splitting the point. Very consistent from one bit to the next. It takes less than 30 seconds to sharpen a bit. Pay attention to the setting on the "web diameter". You don't have to be super precise as you set the knob, but neither can you be way off on the diameter of the drill. I've gone through a good part of my drill index, sharpening the bits that are worn and damaged by my attempts to sharpen free hand. All are usable again. Now, the down side. Little things, but still.... No name plate, no sticker with the voltage and current draw, not UL listed. The response from the seller was that it's in the manual. I'm pretty sure it's required for to be on the device on electrical equipment in the USA. NO instructions at all on how to adjust the center of the drill, just a picture showing that it exists. It's important to have it right to get the relief angle and web diameter right. Mine wasn't set right. No warranty. As has often been said, if it isn't written down, it doesn't exist. When I queried the seller, they said 1 year - and I have a screen shot of that. But stuff happens, things fail that shouldn't, which is why warranties exist. I can't find it on the desertcart page, it's not in the manual. I'd be more comfortable if they fixed both issues. Having said that, I'm still giving it a 5 star rating because it's made well, and sharpens bits very easily and exceedingly well.
Review: Makes bits better than new - Purchased this at full price I sent a couple years contemplating buying it never wanted to spend the money but either needing a new set on bits for about the same amount or buying this so I went for it This sharpener might be the best thing I've ever purchased for my hobby machine shop small amount of tinkering on the setup fixture to learn the dial is off by a few number to align the cutting edges with the flats on the holder but 30 sec later and you have a bit that is sharper than a factory bought only wish I could've justified buying the bigger one the results from this make drill dr ( which I have) look like a caveman's tool Hands down if you need to sharpen your bits get it
