Very Easy To Use 03/18/2020 11:06:17 PM

I picked this up last year at the tent sale, once home I gave it a test. It took a bit to get the hang of it but once I did I was very impressed. The directions can get a little confusing as this grinder is actually meant for metric drill bits when doing a set up. I found that using a digital caliper to measure the drill in metric setting made it a snap. It is way easier to use than my drill doctor

I bought one of these a couple of years ago and have sharpened 100's if not 1000's of bits with it and it is truly worth every penny. I was really skeptical at first but not after the first couple of bits I sharpened you cant go wrong on this

Valuable tool to have! 06/28/2018 10:10:03 AM

I just bought this sharpener. I had figured that I would wait a little while to post a review, to see how it shakes out. I had a hard time finding anything on it, so I definitely wanted to do a review. But, I am so impressed with it, I decided to go ahead. I do a lot of drilling- 40+ (sometimes well over 100) holes a day through 1/2" cold rolled steel, 5 days a week. I needed good bits, all the time. So, I bought a Drill Doctor. The reason- the wide difference in prices between a Drill Doctor and other machines. I've mastered the DD, and sharpened a LOT of bits with it over the last 3 years. It worked, but it took a lot to get the trick, and it doesn't sharpen them as well as I really needed- they have never been better than a new bit, but close. I came to the decision to buy something better, and started the search. I've bought other tools from Grizzly, and have been very happy. I looked at the H8203, as well as some other brands (considerably more expensive). I went for the Grizzly, because of my experiences with my other purchases. It arrived 6 days ago. I went through the manual, and set up the H8203. It wasn't bad, because I was so familiar with the DD. I sharpened the first bit, figuring that there was going to be a learning curve (based on how long it took to master the DD). Tried out that first 3/8" bit through some 3/8" steel, and man! It was better than a new bit. It cut faster, didn't walk, and that was on the first one! I've since sharpened about 10 bits or so, in different sizes. The quality and consistency is leaps and bounds better than the DD, and the bit cuts better than a new one. That's why I decided to write a review so soon- I am so enthusiastic and impressed with it. It is heavy, and exudes quality. I expect to get many years of service out of it, and that it will pay for itself in short order. It was easy to set up, simple to figure out, and I can sharpen a bit in less than a minute. It exceeds what I was expecting.
