The 7" HDII Flange Wheel – Built for the grind, backed for life.
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.
