BUCKTOOL 370W Bench Grinder 150mm Double Wheeled with LED Light Spark Protective Covers 2980RPM Induction Motor Professional Wobble-free Wheel Grinder HBG625

Muy buen, pero muy buen producto de calidad, recomedable

This is quality piece of equipment. Well made very precise and quiet during operation

The grinder works great and is doing a great job of sharpening my turning tools, eventually I will replace the oxide wheels with CBN wheels, but for now the 80 and 120 grit is going a great job. I love the 1.5 inch wide disk, but wish it was the 80 grit. My disappointment is that the threads for the vision guards were not threaded properly, I had to chase them both with my tap and die set and replace one of the bolts that came with the grinder with one of my own.

Well made, quiet motor, solid and steady with no wobbles at all.

I began my search for a new 8" bench grinder with a good deal of pessimism. My history with these important tools has been mixed. I have a couple of well-made 6" grinders, but they are underpowered, and I really wanted one with 8" wheels for grinding my turning tools. I am replacing the equivalent model made by Rikon. Right out of the box both wheels of the Rikon wobbled badly. I took it back to the retailer, who insisted that the grinder itself was fine and that the wheel collars were a little asymmetrical. All I needed to do, he said, was to fiddle around with them until the wheels ran true. That didn't work, nor did turning the collars flat, or replacing them with precision-ground ones. Finally, I checked the grinder itself with a dial gauge, finding that both arbors have significant runout. The grinder has sat mainly idle for several years now. Having recently bought several high-dollar items for the shop, I decided that I couldn't justify buying a name brand like Jet or (gasp!) Baldor. Turning to reviews, I saw that the Buck (which I had never heard of) was highly rated. I managed to suppress my skepticism and ordered one. Being about 70% certain that I was going to end up returning this grinder, I decided to check everything before even switching it on. I was dumbfounded to find amazingly tight tolerances! The arbors (shafts sticking out from either end of the motor) are within 0.0002" of perfectly round, and the steps against which the collars rest are within 0.0004". The collars themselves are another matter. Although robust and apparently well made, they are not machined, and near their edges (they have a diameter of just under 2") they wobble by 0.006 to 0.008". That doesn't sound like much (about the summed diameters of 2-3 human hairs), but where it counts, on the periphery of the 8" wheel, that translates to about the 0.025" that I recorded there. I switched out the collars with the aftermarket, machined ones (made by Raptor) I had on hand from the Rikon failure, which wobble only by 0.001-0.002". I consider this to be really stellar performance for a bench grinder in this price range! The Buck grinder is nicely finished. I was delighted to see that the wheel covers, although stamped and not cast like a Baldor, are of heavy construction, probably about 1.5 mm thick (about 16 ga). This is a really high quality grinder for the price, and I highly recommend it.
