Grind it off

Had to clean up a concrete floor glued grout mastic. No problem

Does a good job on marble

Over priced like all Dewalt stuff; but it worked well.

grinding wheel

Did a great job grinding down concrete high spots in new garage. Used on wet floor to minimize dust.

Grinding wheel

Worked very good taking the old parjing off of our foundation, haven’t finished but it looks like it is going to last for the whole foundation.

Cuts though like budda!!

Had to remove paint and mastic from a cement basement floor. After several several other attempts with other type bits, I broke down and bought "The Judge". Use with a dust shroud or you will be in a dust cloud! It bites hard and fast.

Dewalt Dependable

“Dependable diamond blade by Dewalt is always on the job pulling its weight, and gets my 2ThumbsUp!”

A brand you can trust!

Does a great job in half the time as single wheels. Worth the price!

Solved Painted Patio Problem

I used this wheel to remove 2 layers of paint from my patio. Took 2 days to remove 240sqft, but all the solvents I tried just made a mess. Definitely a better choice.

Does a Great Job, Makes a HUGE Mess!

This wheel does a fantastic job on concrete: Smooths it down in no time and the wear is acceptable. The problem is that you don't appreciate how much of a mess (dust) it makes until you go to clean up. The dust is very fine, stay airborne for a long time and gets EVERYWHERE. It *might* help to wet the surface first...wish I had tried that, but in the end, it got the job done.

AWESOME !

Bought this to not only remove adhesive on top of a slab of concrete but to level and refurbish the concrete surface as well. Was a bit skeptical at purchase time but after about a half an hour of use this tool is incredible ! Went WAY above my expectations ! It ate away the adhesive without effort or problem and smoothed and leveled the surface too ! HIGHLY RECOMMEND IT !

emove Glue from outdoor carpeting job

Old carpet was removed and the old glue was dry and tough.. This tool did a very good job of cleaning the concrete back to a nice smooth finish. Warning though it is a dusty job to say the least. You need a good strong fan to blow the dust away and wear a good respirator mask and goggles for eye protection. Nasty job but someone had to do it. Without a tool like this it would have been a very difficult job.

Grinder wheel for removing glue from concrete.

I was looking for a chemical or tool to remove carpet glue from concrete in preparation for ceramic tile. I removed 90% of the brown stuff with a manual floor scraper that I purchased. It was tuff on my back to say the least plus the periodic blade sharpening. It did the job. Still I was left with residual glue. I was hesitant to use any toxic chemical for this, only as a last resort. Upon reading some online reports and reviews I spent the $50 on this diamond wheel. It fit my Millwalkee grind...

Safer and faster than cable twist wire wheels.

I had to grind off 25-year old construction adhesive left after removing faux foam ornamentation from 3 stucco'd pillars. After an hour, I was bleeding from 3 puncture wounds caused by embedded wire bristles in my forehead, arm and leg, and, I had only cleaned up about 15SQFT of surface when the bristles wore down to nothing. The Lowes sales rep suggested this pricier diamond wheel. Wow! In an hour, I completed another 80 SQft of surface, no brush splinters, and the wheel was only about 40% ...
