Review on 🔨 Bosch CSG15 Concrete Surfacing Grinder: Top-notch Performance and Precision by Chris Chincuanco

Good grinder. I used it to sand down the burrs on the concrete slab before laying the laminate. However, one thing prevents me from giving the coffee grinder five stars: 1. The wheel cup fell off twice. Both times I turned off the grinder, picked it up off the floor and waited for the cup to stop spinning. Somehow this allows the lock nut to loosen and loosen with the wheel. I stopped lifting the grinder off the ground when turning it off until the wheel stopped and I had no more crashes. I'm sure the lock nut was tight before it came loose on both occasions. Also, the coffee grinder tripped the circuit breaker in my house 4-5 times in a single day. Each time this happened, I squeezed the grinder a little harder. However, this cannot be compared with a coffee grinder, 12.5 amps and a large shop vacuum cleaner on the same circuit are pretty close to the limit. I feel the grinder was a little pricey but worked really well, no dust.
