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 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 :)

Not for the faint of heart. It will do a good job, but requires practice and patience to get the set up correct. Practice on a blade that you don’t mind destroying and then use it on better blades after you’ve get the hang of it.

unfortunately after attempting to calibrate this machine to make it work. the tolerances are gust two sloppy motor runs at a good speed but there is end play on the shaft. along with movement on the stops and the in/out slide the machine ruined the blades

Just got it set up and sharpened my 24” buzz saw blade. As heavy as the base is ( made out of cast iron) this blade, when mounted would almost tip the sharpener over. Won’t be a problem with smaller saw blades. I had to make a center adapter for this blade had a larger hole than the ones supplied with the unit (not a problem for my shop). It comes with a diamond wheel. Some indicate that they don’t get but one or two blades sharpened before it wares out, but in their pictures they are not using the water cooling. Take the grinding slow and use the water cooler and it should last thru several blade sharpening. The diamonds don’t ware out, they get knocked out of the binding material. The angle markings seem to be spot on, this makes the set up quick (once the individual blade settings are figured out ).

Disappointed in the condition of the sharpener out of the box. The adjustable blade arm for the slide was extremely dirty and rusty, all stickers for gauges, alignment and warnings are crumpled and peeling off. Pushing them back on sticks for a few seconds and then they peel again, and the supplied allen wrench is too long to adjust the stop pin. Would not cost any more to oil the arm to prevent rust, take more care applying the stickers and provide the correct wrench!!! After correcting the issues I ran it. The motor is smooth and the blade sems ok. We will see how it holds up.

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*

Not a bad little machine… Just kinda hard to use

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.
