Whether you’re an aircraft mechanic, auto mechanic, welder, or DIYer, you’ll eventually need to grind or sand some metal. But what happens when your angle grinder doesn’t offer the finesse you need for a small, intricate job? What happens when you need to get into a hard-to-reach area? Here’s a solution that takes advantage of a tool you already have — 3M’s Roloc drill-mounted grinding/sanding/finishing system.

The kit comes with three Regalite grinding discs, two Scotch-Brite discs, and a 2″ Roloc backer pad. Just insert the backer pad into your drill’s chuck to remove paint, filler, corrosion, rust, and gaskets with ease. Use the Scotch-Brite discs to polish metal, finish disc brakes, and clean up welds.

Once you have the backer pad, you can buy all sorts of other Roloc discs to better suit your needs — like the abrasive-filled bristle disc, for deburring, blending, and cleaning metals. The pads’ll also remove defects and scratches. You can even attach the backer pad’s 1/4″ shaft to your favorite die grinder — just be sure to check your RPMs.

I got my system at the (now closed) Boeing surplus store in Seattle, but you can get yours at many brick-and-mortar auto supply stores or on the web. Street pricing starts at $15 for the kit, and you can find all kinds of discs in different quantities and prices online.3M Finishing Kit [3M]

    wait, the boeing surplus store closed? NOOOO!

    i lived in seattle in the late 90’s, and it was one of my favorite places to get really odd tooling parts.

    I am moving into a house with garage that I plan to turn into a woodworking shop where I can produce a very fancy, artistic ‘stick horse” for children from 3 to 73, for play or for home decor or a smaller version for stable doors to post the occupants name. I don’t really need the pneumatic tools directly for this project, but indirectly, I need them very badly.

    I am a 66 year old female who loves to work with wood. I was hit with a spinal cord injury about 3 1/2 yrs. ago that put me in a wheel chair. I still get around pretty good, but I’m going to need to build a ramp out of the house, saw horses, a work table, free standing shelves, since the garage is a masonary building, etc. As you can see, I certainly could put a nailer to use.

    M.B.

    P.M. I really like the look of 3M’s Roloc Surface Finishing Kit also. Now that could work fine on my horses. These are going to be the most realistic and pretty “stick horses” you can imagine.

    I have one of these kits, have used it a lot for buffing metal, and really like it. However, the mandrel is cheap plastic and tends to crack, and you can use these in reverse (as is sometime necessary) because they thread in. That said, they’re cheap to replace if it breaks. I just wish more stores stocked the discs (most just stock the kit).

  5. Brau says:

    Correction: Should have written “can’t use it in reverse”

  6. Try Qwest auto parts, they had a lot of Roloc discs including the bristle discs last time I was in there. If you don’t live near a Qwest then you can try Lowes, although its a nock-off brand, they sell 2″ discs that will work with the system.

    Grainger has these kits as well as replacement discs. Enven though Grainger is B2B, there is always a way you can purchase through them. Chances are, the company you work for has and account that you can use.

    In some parts of the country, you can now order Grainger items through Lowes.

  8. Bart'sDad says:

    Most automotive supply places also carry boxes of the discs in 25 counts. We go through these like water in the shop.

    Yeah I’ve used these, they’re great for removing gasket material.

    I tried them, they are very much helpful to me
