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]
