The Milwaukee 49-16-2660JS Jaw Set for M18 FUEL 1/4-Inch Blind Rivet Tool is a replacement jaw set built for Milwaukee's M18 FUEL 1/4 inch Blind Rivet Tool with ONE-KEY, model 2660-20. This is a rivet tool jaw set designed for restoring proper gripping performance when the original jaws wear down. Model Number: 49-16-2660JS. If your blind rivet tool is starting to slip, miss pulls, or need more repeat attempts on the same rivet, this is the service part that gets it back to doing its job.

Milwaukee uses a 3-jaw design here, which matters because the jaws are the part that actually grab the mandrel during the pull. When that gripping surface wears, riveting gets slower and less reliable. Replacing the jaws instead of pushing a worn set too long helps keep pull consistency up and wasted rivets down. Milwaukee also calls out premium alloy steel construction, with a stated service life up to 2 times longer, so this is aimed at users who run their rivet tool enough to care about wear parts and maintenance intervals.

This jaw set installs 3/16 inch, 7/32 inch, 1/4 inch, and 9/32 inch blind rivets, which gives it useful range for common fastening work in metal fabrication, equipment service, and general assembly. That size coverage is important if you are using one rivet tool across multiple fastening jobs instead of keeping separate dedicated setups. The point is simple: keep the tool pulling the rivets it was built to handle without fighting worn consumable parts.

On the practical side, Milwaukee designed these jaws for easy swapping in and out of the tool. That saves time during maintenance and cuts down on routine service frustration. For crews and techs who depend on the 2660-20, quick jaw changes matter because a worn gripping set can slow production long before the rest of the tool has any issue. This is a small part, but it directly affects how well the blind rivet tool performs on the job.

Compatibility is specific, which is worth calling out clearly. This jaw set is made for the Milwaukee M18 FUEL 1/4 inch Blind Rivet Tool with ONE-KEY 2660 only, sold separately. It is not positioned as a universal blind rivet accessory. If you own that exact Milwaukee cordless rivet tool and want the correct replacement part from the same brand, this is the right fit.

Who should buy it? Anyone maintaining a Milwaukee 2660-20 blind rivet tool instead of replacing the whole tool because of normal wear. It makes the most sense for metalworking, mechanical service, fleet maintenance, trailer work, panel fastening, and shop or field users who install blind rivets regularly enough to burn through jaws. For occasional users, it is smart to keep a set on hand. For heavy users, it is just routine upkeep that keeps the tool productive.
