Question: Does this grinder have exhaust ports on the guards to allow connection to a shop vac?
Document: The second one is good-to-go. I use the grinder at various places on our farm here and always previously had to clamp down the old six-inch one, but this Metabo is so smooth that I just put it on my shop card and use it there with no stabilizing necessary.
After a ton of research I purchased this Metabo DS 200 and love it! It is super quiet, well made and durable. I use it for all kinds of metal work, grinding and sharpening. Must have for a metal shop. I do light fabrication and love this grinder.
This German-made bench grinder is quality throughout. It comes to speed in under 10 seconds, but the grinding wheels keep turning for 3 minutes after shut-off. The bearings are obviously top-notch. The only small gripe I have is that there was only a small exploded diagram to aid in assembling the eye shields and grinding platforms. This grinder will without a doubt last for many years in a home work shop environment.
Grinder works as its supposed to. Wheels are somewhat hard to find in the spindle size needed to fit . This is in addition to two Jet bench grinders I have in the shop. I use the Jet grinders every day finding them to be tough and able to handle all uses I put them to With the limited use of the Metabo thus far, I find it to be as useful as the other grinders. No balance problems, or wobble.
I timed the time it took for the grinder to come to a complete stop after turning it off and I was amazed when it took over 90 seconds to completely spin down. I think this is a hallmark of good bearings with lots of inertia from the spinning wheels and motor.Like others have observed, the eye guards aren't great - they are a little on the small side, but that's not an issue at all since I always wear a full face mask when grinding.
I mounted a Hitachi 729306 brush (purchased on Amazon) and it works well. Although advertised to fit  1/2 to 2&#34; arbors, I had to enlarge the hole in the plastic center pieces to fit on the odd 1-1/4&#34; bushed flange on this machine. i also had to make a large spacer/washer to position the wheel and allow the flanges to grip it properly (I cut one from a piece of plastic).
The flange must be used as it is spaces the wheel away from the body of the grinder so it clears.
This grinder is great. No wobble, it worked perfictly out of the box. I think this tool will last the rest of my carrear.
i have had many cheap to good (delta) bench grinders. worth the extra money for the supper smooth action in this grinder
This grinder is heavy duty. Have used it none stop for two weeks with problems. Well balanced and well built.
