The Milwaukee 7/8" & 1-5/8" x 1-5/8" Combination Strut Shearing Dies, model 49-16-1578, are a replacement and application-specific die set for Milwaukee strut shearing equipment. This is a strut shearing die set designed for cutting standard strut profiles with clean, consistent results. If you already run the Milwaukee M18 FORCELOGIC Single Channel Strut Shear, this die set gives you coverage for 7/8 inch and 1-5/8 inch by 1-5/8 inch standard strut sizes in one package.

What matters here is not just the size callout, but what it does on the job. These dies are made to deliver accurate, repeatable shears, so you get cuts that are ready for installation instead of cuts that create more work. Milwaukee also rates the set for up to 10,000 shears per die set, which matters for contractors doing high-volume strut work where wear life affects real cost over time.

Milwaukee built this set specifically for its M18 FORCELOGIC Single Channel Strut Shear, not as a one-size-fits-all accessory. That exclusive compatibility is a good thing. It means the dies are engineered around the tool's shear mechanism, retention system, and intended cutting geometry. The result is a better fit and a more predictable cut than trying to make a general accessory do a dedicated job.

Jobsite practicality is clearly part of the design. Tool-free die changes help keep the shear moving between applications instead of sitting on the floor while someone digs for wrenches. Laser-etched markings help with size identification and installation, which sounds small until you are swapping dies in the field and want to avoid installing the wrong set. Milwaukee also calls out that there are no exposed blades, which is part of why strut shearing is often a cleaner, more controlled option for this kind of work.

Material and size details are straightforward and important. The dies are steel, the set weighs 1.61 pounds, and the overall dimensions are 3.11 inches long by 3 inches wide by 0.75 inches high. This set is intended for standard 1-5/8 inch wide strut and 7/8 inch strut height applications. Milwaukee also states these dies are for up to 12 gauge 1-5/8 inch by 1-5/8 inch strut, and specifically notes they are not for use in stainless steel strut.

For the right user, this is a productivity accessory, not a generic replacement part. It makes the most sense for electrical, mechanical, plumbing, and general construction crews that install a lot of channel strut and want faster, cleaner cuts with the Milwaukee cordless strut shear platform. If you own the compatible M18 FORCELOGIC shear and regularly work in these strut sizes, this is the die set that keeps the tool useful across common field applications.

A must-have die set if your crew lives on strut

The Milwaukee 7/8" & 1-5/8" x 1-5/8" Combination Strut Shearing Dies make a lot of sense for anyone trying to get more range and less downtime out of the M18 FORCELOGIC shear.

• Who it's for: Contractors and installers already using the Milwaukee strut shear for electrical, mechanical, plumbing, and HVAC support work.
• Why it stands out: Exclusive tool fit, clean repeatable shears, laser-etched markings, and tool-free changes all add up to less messing around between cuts.
