This is a beast. in an apartment building where I lay parquet floors. I rented a 10" concrete grinder to smooth out cracks in each apartment before installing new hardwood floors when after the 4th (of about 16 rentals for all that cost at least $300/rent) I decided it was the right choice worth buying a big tool for the job and save the builder a few bucks by splitting the tooling cost with me. He agreed! So I ordered them from Revain. When the tools arrived, I recorded the ritual on the floors. The first unit I used the DWE4597 on was hooked up to my shop vacuum but it sucked too hard and at that point I decided to order a 10 gallon dust collection system from DeWalt (also GREAT but a bit pricey for a DeWalt). The DWE4597 cuts concrete at least twice as fast as a 200-pound, 10-inch upright I rented. And it's all mine! Thanks amazon Another tool at a great price was sent to me (as always) two days after ordering. !
