The Handi Disc II is the ultimate cutting, sanding, and grinding wheel. The surface and edges of the wheel are covered with over 6 Karats of 46 grit diamond. At 10 on the Mohs scale Diamond wins every contest, put this wheel up against almost any material and it will cut, sand, or grind its way through.

    My son and I work in the marine industry and just last week I used the HDII for the first time. i had a damaged fiberglass hood that required major repair. I used the wheel to first cut out the damaged area and after the initial buildup of glass used the flat side to shape the bracket posts, didn’t clog at all and cut very fast without binding.
    My son could not get a U Joint cross out of an outdrive input shaft so I had him try the disk using only the edge to cut thru the hardened cross…. 4 mins later it was cut clean.
    We will be using it a lot more and I will order the cupped version..
    Will update as I come across more uses that are challenging to us in the field…

    Can’t say enough good things about this wheel! I’m a hobbiest blacksmith, and do some light metal fabrication work, vehicles, around the house, art projects, etc. I admit, I was skeptical. Grinding with a cutoff wheel? YGBSM!?!? Well I’m here to tell you – it works! My wife bought me one for Christmas and it works! Way better than a standard cutoff wheel. You can cut faster, grind, do things you would never do with a standard cutoff wheel. I’m a pilot for my day job and I’m paranoid about protecting my eyes. I’ve been using the heck out of this thing for a while now and it still looks shiny and new! I love it. I’m buying it for gifts for all my friends that do metal work. One of those rare products these days that performs exactly as advertised! Thanks Bad Dog Tools!!!

    This is a great product. I don’t know how I could ever get along without it. So many projects, so many uses- AWESOME! It’s actually the best Christmas gift I ever received (from my wife).

  5. Robert P

    Bought this a few yrs ago at the BigE after buying the saw blade OMG I cut through everything I have this one and just picked up the smaller one for tight spaces

  6. Twah

    I’ve cut hundreds of feet of steel for projects. Grinded hundreds of welds. Cut stone and concrete blocks without issue! Best cutting tool you can buy!! Some of the best money I’ve ever spent. Saved so much over the old style cutoff wheels
