Good performance and good quality.

Good plug!

Good plugs, nice performance!

The performance of the the plug is very great.

Worked well on my old concrete, great!

So far, this has performed very well. I am grinding down high spots on my concrete slab and it worked very aggressively. Very pleased with the job it did!

Worked without any problems. I didn't expect it to work for so long since the price was cheaper than that I bought before. But the tools are very durable.

Bought diamond tools from DTS store for the third time. Always in good quality, good service and fast delivery. What a trusted supplier! High Recommended.

I purchased this to prep a concrete floor prior to laying down some vinyl tile. No issues at all. This was two days worth of grinding and the grinding plug still has more than 80% of its life left. It ate through the 4500 psi concrete. Awesome!

Item as described. High quality and nice package for a decent price.

The grinding plugs are very powerful for opening steps on the uncoated concrete. They have not worn too much so far since I just used then for a small area. But they seem very good quality at a reasonable price.Will buy more for my next project.

The terrco plug performed well as the plug I bought from the local store but the price was much cheaper. Fast shipping and well packaged.

Aggressive terrco plug. Delivery on time and good packing.Deserve a five star.

Fast ship. So far the plugs worked great! and same performance as the terrco plug I bought local store. Happy deal!

Very fast shipping, did a great job on surface preparation grinding.

Fast grinding, works well on old concrete, next month I will buy some soft bond plugs for my new job.
