Bad DogTools 4.5” Endless Handi Disc Deux (HDII) Diamond Wheel for Grinding, Sanding, and Cutting. Use on Iron, Steel, Brass, Tile, Stone, Brick, & Plastic. Use with 4.5” Angle Grinders.

Best disc and probably the last one I will ever have to buy!I've been using this for months and it looks like it's never been used! Cuts and grinds awesome! Maybe seems expensive, but I don't see ever needing to replace it. And if I do it's warrantied!!

I have used the wheel to cut and grind mild and stainless steel and the performance is great. better than any other cutting wheel you will buy amazon. does well grinding; but the cutting is what really impressed me. also very nice to be able to cut and grind without switching tools.

This cutting wheel has been working great in my Dremel for the last year. It's not as precise as Dremel discs due to its size but it doesn't ever need to be changed due to its durability.

The price tag is steep but if the lifetime warranty is genuine, it may be worth it. So far I have cut and/or ground plastic, wood, aluminum, and steel and it just keeps on cutting. The grinding surface doesn't seem to blind when cutting softer materials. I'm a fan so far.

Blade can be used as a cutter and grinder. Kerf width is 0.10” (2.5mm).Use with "NIKX STIKX Metal Cutting Compound" is not a lubricant but is applied to cutting tools and saw blades to keep them cutting smoothly. The waxy compound is rubbed on and can’t spill like liquid coolants.

I cut a lot of scrap and was going through box after box of fiberglass wheels. Then I found this and my world changed. I just got done doing three mixed reels of metal (steel, copper (drop cord) and fiber and tits still cutting. Normally I would’ve gone through 100 fiber glass cutting wheels with this amount of heavy scrap. This thing lasts. I’m interested to see how long it will go.

My husband had me buy this for his job (welding) he loves it

This thing is a beast. Stays cool and cuts clean and fast though. As a stone carver, this is my go to blade.
