Lifetime Customer Support

We're a proud US-based company, and we offer LIFETIME customer support. If you dull or damage your HDII, send it back and we'll repair or replace it.

  • We offer several different size HDIIs for rotary tools and various grinders. The size of our arbor holes follow industry standards. Please see the specifications image for each HDII, as well as the bullet points, for more information.

  • Wood - It will shape wood well but burns when cutting. Glass - The HDII is too aggressive and leaves a jagged edge.

  • Nothing lasts forever but we offer Lifetime Customer Support to repair or replace our HDIIs!

  • Sometime when cutting softer metals like aluminum the HDII will "gum" up. If this happens to you, simply run your HDII through a concrete block and it will be good as new.

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!!

It works but not as quick as my regular wheels. Wouldn't purchase again but for safety reasons it's a good disk to have in the shop for my guys

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.

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

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.

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.

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.
