Bad Dog 6″ HDII – Faster Cuts. Bigger Bites. Same Lifetime Grit.
Looking for more speed without sacrificing control? The 6″ Bad Dog HDII delivers the same unmatched cut, sand, and grind versatility as the rest of the HDII lineup—but with a larger cutting surface for faster, more efficient performance.
Built for serious material removal, the 6" HDII features 46 grit diamond on both the face and edge, letting you attack your workpiece from every angle. Whether you’re slicing through metal, masonry, porcelain, PVC, tile, or wood, this wheel gets it done—fast.
The increased diameter doesn’t just boost cutting and grinding speed—it also spreads heat across a wider surface, reducing wear and improving lifespan. And thanks to its steel core, the HDII won’t explode or crack like fiberglass wheels if it binds up. That means more safety and more confidence on the job.
With a 7/8" arbor, the 6" HDII fits most 6" angle grinders, making it a perfect choice for pros and DIYers looking to maximize power without jumping to a larger, heavier setup.
As always, it’s backed by the Bad Dog Lifetime Guarantee—wear it down, chip it, break it—we’ll replace it. No questions. No nonsense.

Absolutely. The industry standard for grinders is as follows: Rotary Tools (i.e. Dremel TM) - 1/8" 3" Cut off tools and Die Grinder - 1/4" & 3/8” 4" Angle Grinder - 5/8" 4-1/2", 5”, 6", 7" Angle Grinder - 7/8" arbor flange for a 5/8" coarse arbor shaft At Bad Dog, we find that an HDII with a 7/8" arbor flange runs truest because it is a more precise fit. The 4-1/2" and 6" Flange wheel use the 5/8" Coarse thread which is standard on ALL grinders. Call us at 800.252.1330 if you have any questions.
Wood: It will shape wood well but burns when cutting. Glass: The HDII is too aggressive and leaves a jagged edge.

We'll replace it - even if it's your fault! Here's a link to the details of our Lifetime Guarantee.
Sometimes 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 as good as new.
As safe as they get! Cut-off wheels can be some of the most dangerous tools in a shop. We are not telling you that you don’t need to be wearing safety when using our wheel, however, the 46 diamond grit is embedded on a hard steel plate to ensure that the wheel will not fly apart on you.
