Review: Tough, Hardworking Grinder - I bought this grinder to use with poly abrasive stripping discs to remove paint on an older ranch house. I appreciate that the grinder is not heavy while still being beefy. The grip is small enough to run one handed, which I needed to do often while stretching arms length at the top of a ladder. The left-side push switch took some getting used to when using left handed. The constant on function works easily...push the switch forward and then press inward. I ran this grinder continuous for up to 15 minutes at a time, through a 5 pack of abrasive discs, over three days, grinding off old paint on wood siding. The grinder got warm, but never overheated. I was impressed. I like the safety guard. It fit the 4 1/2" x 7/8" poly discs perfectly with no contact. The guard requires an Allen key to loosen and reposition it. A clamping guard would be a plus. The auxilliary handle can be used on either left or right. One thing I. like is that the Allen key for the guard, and the wrench for the blade nut are all in one piece, an interesting tool, a little different from the standard wrench. The holes in the blade nut are standard width. It took me about one minute to assemble the tool out of the box. The single speed is rated 11,000 rpms, and I note it runs constant, and has not bogged down in my use. The wheel-lock on the back is red, and is easy to use while changing a blade. Glad I bought it. This is an excellent quality tool for professionals that definitely goes to the job site. Review: 100% Recomendado - Exelente producto!, como siempre Bosch no decepciona.
