What our customers have to say about the Bad Dog HDII Multipur...
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.
Nothing lasts forever but we Guarantee the HDII for LIFE! If you ever dull or damage your HDII return it to us and we will repair or replace it. For full details see our Lifetime Guarantee page.
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.
