VEVOR Circular Saw Blade Sharpener, 370W Rotary Angle Mill Grinder with Water Tank, Water Injection Grinding Sharpening Machine & 6 Saw Centerings, 5-inch Grinding Wheel for Carbide Tipped Saw Blades

I started by tearing the entire thing down to clean and lube all the parts and understand all the adjustments possible. This is something you probably want to do to get the smoothest operation. I also bought an assortment of grinding wheel grits since I didn't know what grit was included with the machine or what would work best for the types of blades I had. There are many grits available in the 125x10x32x8mm size that fits this machine. After comparing the ones I bought separately (#150, #180 & #400) I can only guess the stock wheel is about #120. It shows up unmarked and seems just a bit more course than any I bought. The stock one is good for heavy material removal on blades that are in really bad shape (burning your wood) but if you just want to touch up a serviceable blade even 150 might be too course. If you can get a water dripper for this it's definitely worth the trouble. It seems to be designed for one and dry grinding loads your wheel quickly. Especially if you use something finer than #150. It's probably why they deliver such a course wheel. The stock one doesn't load up too quickly.

Instructions are worthless. Setup is a bit of pain in the ass, but once set up it seems to have sharpened well. The spacers do not match the holes in the blades very well (10” & 12” dia. blades), but was able to adapt. The product works but requires some patience for setup. Would recommend product for people with some ingenuity.

Great saw blade sharpener! Once you figure out all the adjustments needed to get started, the machine works well. After the set up is complete, you can sharpen a ten-inch 80 TPI saw blade in about three minutes. It’s a little heavy, but stores easily if you remove the adjustable angle arm which makes the unit about 13 inches long.

Instruction manual very poorly written leaving you to guess at how to adjust blade for proper indexing. The slide mechanism is sloppy. The motor does appear to run very well and quiet. But if the blade can't be properly indexed for each tooth your better off going to a saw blade a professional sharpener. I'm pleased that Amazon has a good return policy.

I ordered this knowing from watching videos on YouTube that the arbor sizes are metric not standard. That being said when I received the order I ground down the arbor shim for the center of the saw blade to fit as it is a hair too big. Works wonderfully no issues to complain about, I also 3D printed custom shims for it as well. Really easy to use and works well sharpens the blade like new definitely saves you money after a few uses. For me for a 10” blade different tooth counts it will cost between $25-$35 plus shipping of $7-$10 to have each blade sent it to be sharpened, that’s $32-$45 each. I hope this helps :)

You know how people always rag on "Made in China" meaning its made like crap? Well, that hasn't been true for a long time. A lot of very good quality stuff comes out of China these days. Except for this thing... its still made like crap - at least half of it is. All of the frame is nice and sturdy +1* A bunch of the parts came 100% rusted over -1* The motor works good enough +1* The shaft on the motor is kinked and wobbles significantly -2* I was able to machine a new hub and rotate it out of phase just right enough that it fixed the wobble. +2* It does the job in the end after a bunch of work +2*

Works fairly well and can do the job it was suppose to do. BUT- the 6 different-sized saw centerings attachments are off size and on my first use of 4 blades with the smallest centering piece, I found out that they are threaded and mine came loose all the time ( maybe user error? ) Asked if this unit will face & top & side grind and the reply was yes it will do all 3, it will do the face & tops of each tooth but not made to side grind at all. The blade stop is finicky as can be, I am going to make my own so I can take the same amount of material off each tooth. Unit has the power you need for sure. Water cooling needs to be adjusted carefully as it is just a clean hose from the tank, wish it was a thin & small copper pipe so I could mount it so it want move out of place. For the price I am still making my mind up and this all might not be fair as I used to sharpen carbide blades for a living and the unit was over $1500, this is way less.

Fit, form and finish is not very good. So be prepared to sand/deburr on it before you can begin using it. Collets to hold the blade in place and allow it to turn will have to be sanded in a way not to comprimise roundness. I used a wooden dowel rod and a hand drill with sander. I almost want to say the one I bought years ago from Harbor Freight is a little easier and better to use. It's solid built for sure but no room to turn knobs is a pain in the (***) Kinda dissapointed in the youtube reviewers. Seems money and views have most of them by the balls. The best looking and feeling knobs on it are for the machine to sit on. I suppose it will work good enough for me, but definitely not to sharpen blades as a business at all. If it gets any better I will try an update.
