DESCRIPTION
DAMO's cup wheels are designed for profiling edges, smoothing out inside sinkhole cuts, smoothing rough surfaces, preparation of material for lamination and heavy stock removal. They are the premium choice for any grinding, shaping or beveling work of concrete, granite, and other stones.Utilizing the latest "Multilayer Vacuum Brazed Technology," the cup wheels are super aggressive, so the operator doesn't need to apply a lot of pressure when pressing down, the cup wheels will naturally use the gravitational force for operation unlike the conventional cup wheels. They really make the job easy loaded for the operator.All of DAMO's cup wheels are balanced by Dynamic Balancer, which will prevent your angle grinder to vibrate vigorously for unsafe operation as well as premature failure.DAMO's cup wheels are designed with special swirl turbo segments which act as a turbofan for quick cooling of the working cup wheels. This will help prevent high temperatures that will lead to short life and less aggressiveness of the cup wheels.The coarse type (diamond grits 30/40) is used for aggressive grinding. The medium type (diamond grits 70/80) is for slower grinding action.They are designed for dry applications but work very well during wet applications. They can be used on most popular high-speed angle grinders with 5/8"-11 threaded spindles.You may buy seperately our adapter 5/8"-11 to M14 to use with power tools with M14 thread spindle.You may purchase separately our 5" Dust Shroud to help eliminate dusts for concrete floor applications. It is sturdy, simple and collects dusts very effectively with most vacuum systems.We DAMO Diamond Tools, LLC holds exclusive distribution to DAMO Trademark products as you can see clearly marked from the picture on the product listing.

I needed a diamond grinding wheel that would attach to a small bosch angle grinder to shape and form some limestone slabs for a water feature I am building in my back yard. At first I balked a little at the cost of this tool but now that I have used it I realize it is worth every penny. It does exactly what I need it to. Fast material removal, good surface finish and its stood up to a LOT of use and still going strong and has plenty of grinding material left. I couldn't be more pleased.Used this product to grind a granite cutout to accommodate a larger cooktop. It wasn't pretty but worked well. This was my 1st time using any sort of grinder so I blame the operator for the inexact edge. The edge is covered completely by the overhang of the new cooktop & can't tell it's not an exact square edge. Had to make the cutout about 1/4" deeper & since none of the granite installers in my area were willing to help me out, I accomplished the task with the help of this grinding cup wheel.I had already gone through several cheaper grinding wheels that feel apart before buying this one. Unlike the others, it lasted through many hours of cement grinding. Worth every penny.This worked great! I made a cabinet and had to install granite countertop with two walls. I used this to conform the countertop to the imperfections in the wall.The price was good, but the cup bounces on the surface. None of my other cups and disks do that. The price might be pretty good, but the cup seems a little warped or off center. The trouble is I bought 2 because the price seemed good, but now I have spent money on a product I can't return and don't really care for.Had to grind out and expand the sink opening on a granite counter top and this grinding cup was incredible. Took about 1/4" off all sides of a 22"X25" opening and cleaned up the corners for a new over mount sink. It did the job in under an hour.If you're grinding a concrete surface for stain or epoxy prep, SAVE yourself some money and buy a Dewalt double row diamond grinding cup. This one was double the cost, had annoying vibration and left tons of "kiss" marks no matter how you held it.. The Dewalt was smooth grinding, and lasted much longer!POWERFUL! I needed to round up a rather large rock and this bad boy did the job wonderfully.
