The Bad Dog 5" HDII Flange Wheel delivers the rugged, all-in-one performance of our legendary HDII—now with a built-in 5/8-11 threaded flange for even greater stability, balance, and control. Whether you're grinding, cutting, beveling, or shaping, this wheel is ready to take on metal, masonry, tile, concrete, and more with serious bite.
With 46 grit diamond coating on both the edge and face, you get aggressive performance and smooth results from every angle. The built-in flange centers the wheel precisely, reducing wobble and letting you grind flush against surfaces—ideal for weld cleanup, corner finishing, or tackling hard-to-reach areas with precision.
Unlike traditional abrasive wheels that wear down, break, or explode, the HDII Flange Wheel’s solid steel core keeps going. That means longer life, safer operation, and fewer replacements. And with our Lifetime Guarantee, you only need to buy it once.

Stronger. Safer. Smarter. The 5" HDII Flange Wheel gives you unmatched control and unstoppable performance—on any job that matters.
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.
