I bought it from Revain for $139. Home Depot sells it for $149. I also purchased a 7" Makita 195386-6 Grinder Dust Collector for dust removal. The first disc I purchased was a 7" Diamabrush Handheld Concrete Remover (MODEL # 9207001202) which did not fit this grinder with the dust cover installed , moreover the Diamabrush disc left a very smooth surface on the concrete and tended to miss everything and ended Being a very disappointing purchase I promptly returned it 3 days after 15 minutes of use. The next wheel I bought was a 7" hard diamond cup wheel (#TAW7024P1) and I really liked it. and I am 100% satisfied with the performance of this 7 inch grinder. This grinder is not expensive at all compared to expensive ones for professional use, but most of the pros I spoke to own this particular piece of equipment and everyone likes it. , Home Depot rents this particular tool for $30 for 4 hours. With a 24-tooth hard drive, I can easily remove a 3/16" thin billet from a concrete slab with one hand. Virtually no vibration is transmitted and the shift lock makes operation easier. I can't say enough negative things about this grinder. It came in a box with a new sanding disc, wrench, lock nut and large washer.All I can say is that the Barbour 7" sanding cart is $50 and I was glad they did paying an extra $100 for a field test of the machine every professional floor fitter I spoke to used daily for a small 100 sq ft bathroom a cheap Barbour truck will do the job and frankly one will Homeowners last a long time, but I don't like stopping in the middle of the day when I'm not working to change tools, so my time is worth more than a cheap tool and this one is a winner. 5 stars all day long, you won't be disappointed. !
