The existing hole in my granite counter top was 1-1/4" and I needed to make it bigger to mount a new faucet. I went with this bit and I have no regrets. It took me about 2 minutes to expand the existing hole to get the new faucet to fit. I only used this bit once so I can't comment on its durability but it seems to be of good quality from what I can tell. I would recommend this product.

This diamond milling bit is great for doing some of the fine tuning of stone grinding like enlarging holes or taking off a little extra material. It's meant to compliment other tools, it does not do the majority of removal itself. Very sturdy, coarse grit, it screws right on to a 4" grinder.

This was a fun order to open and examine. During this time I found that the smoothing bit felt nice solid smooth and felt of a quality construction with thought given to proper materials. Now with usage it seems like it is working just as promised and expected. My friend is a contractor and as we discussed this bit we came to the conclusion that until we find its failing point a fair rating of a 5 for consumers and a 4 for contractors. This is only based on the fact that we are unsure of its longevity under heavy daily use. As far as we can tell at this point it will most likely hold up as well as to be expected at this price point. He was so excited to test it out. We are both kind of nutty when it comes to computers, electronics, tools and stuff. Guess we get easily excited in any of those categories. Pros: Quality finish.Quality manufacturing.Quality coating.Cons: Really just a question of longevity.Would I order this again? Yes.Give as a gift? Yes. Overall, I feel that this brand of bits will serve me just fine as a consumer user and feels like a fair value for consumer/hobbiest/general home owner use.

•Overall Impression:-This is a very nice milling bit that is very sturdy and well made. It has a nice diamond coating (grit 50/60) that's well done, heavy duty and should last a long time.-It's not suitable or meant for every application, material or surface. There are some surfaces you are directed in the instructions not to use it on. You can not use it on lumber or metal.• Pros-what I liked and what worked well:-Fits standard devices, easy to put on and remove with the 5/8" thread.-Sturdy, well made base and diamond finish.-Has a 50/60 grit diamond finish. It's well done, heavy duty, evenly finished and looks like it will hold up well.-The domed top and elongated shape of it makes it work very well and easy to use.-Laser engraved size and grit finished on the base.-Rated for use on: porcelain, ceramic, marble, concrete, granite, brick, quartz, masonry, tile.-It's to smooth edges and openings or adjust the size and fit of an existing opening. Note that it's not meant to cut or make new openings, but adjust slightly and smooth them. You'll need something different if you need to make new openings not already on your surface, item or material. This can not do that.-Has no unpleasant scent to it.• Cons-what I didn’t like and what didn’t work well:-No issues.• Tips & Thoughts:-We used it on concrete that already had circular openings and it helped smooth and adjust them a bit for the fit to remove a little of the material to help something fit. It worked very well for this and wasn't a struggle to use.-Always wear eye safety protection during use, there may be bits of material and debris flying during use.-Do not use this on any other material or surface than the ones listed. The instructions say it is not to be used on lumber or metal.-You will need your own device to put it on, no device is included.

I used this bit with my Milwaukee angle grinder. I am very impressed qith it's performance. I used it to carve out a larger hole in ceramic floor tile.I have done this kind of work before but never with a bit that chewed away at material, the way this one does, it had an aggressive bite to it. I wasn't sure how this course coating of diamonds would work with regard to "clogging" but the surface retained it's bite and never clogged with material. After completing the work, I inspected the surface coating and it shows no damage to it, at all. I am surprised by this. The bit has holes in it for water flow, which would extend the life of this bit, dramatically. I am not setup for that right now and I am not even sure of how long this bit would last under those circumstances but it my first experience (dey) is any indication, this bit should have a pretty impressive lifespan.Operationally, this bit is solid and stable to use. It "cuts", it doesn't "dance" and that makes using it, so much more of a pleasure. For it's size and shape, I am pretty impressed at how much control it allows the user.For performance vs. price, this is a really solid value and I definitely recommend it to anyone that wants to remove, stone or tile material. I will be looking at products from Larouoba, that is how impressed I am.

This review evaluates the “0.75” (20mm) Blue Dry Diamond Finger Bit” made by LAROUOBA.The product was shipped with no excessive or wasteful packaging. What’s in the box: one (1) 0.75” (20mm) blue dry diamond finger bit, and one (1) hard plastic case.First impressions: The overall quality of the bit seems good, there is a generous thick coating of diamond abrasive. It fits any standard angle grinder with a 5/8”-11 spin-on arbor. ProTip: for small tile work I use a drill press using a 5/8”-11 female to SDS mandrel adapter (not included) to hold the bit perfectly vertical. For holes into something cylindrical, I use a “Vee” jig in my drill press to hold my round work. Another key element to a clean, easy-to-cut hole as well as ensuring extended drill bit life, ALWAYS use water or oil to cool the bit. Also, it is essential that you don’t “force” the bit into your work – let the bit do its job by providing even positive pressure. Forcing the bit into the work or using the bit dry will excessively overheat the bit and wear off the abrasive coating.Since I am evaluating this product as part of the Amazon Vine program, I am limited to a 30-day window to submit a review. In order to determine drill bit durability and length of life, I intend to monitor this product over the next 12 months. Should anything change over this period, I will update this review accordingly.Cost-effectiveness and value: Overall I am satisfied with the product; it does the job easily and conveniently. Proper care will last quite a few jobs. At a current price of $26.59 (plus a $4 off coupon), I feel that this product is fairly priced for the quality and functionality delivered. In reality, at this price, if you use the kit for one or two jobs it has paid for itself.In summary: the “0.75” (20mm) Blue Dry Diamond Finger Bit” made by LAROUOBA is well made and does the job easily and conveniently at a fair price. I would recommend this product.Pros 👍:✔ Made from good quality materials.✔ Generous amount of abrasive coating.✔ Comes in a convenient hard plastic case.✔ Extremely useful for enlarging existing holes and removing sharp burrs.✔ Fair price point.Cons👎:✘ None!
