Milwaukee’s M18 cordless knockout punch tool deserves some serious attention, but there’s also a lot of interest in their manual punch set. The manual punch set (49-16-2694) includes 6 sets of punches and dies, 2 draw studs, a tube of grease, and a long 1″ ratcheting wrench.
The set comes with 1/2″, 3/4″, 1″, 1-1/4″, 1-1/2″, and 2″ punch and die pairs, with the sizes corresponding to typical electrical conduit sizes. Nominal hole sizes are going to be a bit different.
These punches and dies are identical to those included in the M18 powered knockout punch driver sets, and feature laser-engraved crosshairs for easy alignment, large size markings, and split tooth geometries that break up slugs for easier removal.
Milwaukee’s knockout punch sets are compatible with competitive knockout tools, in case you run out of elbow grease.
Surprisingly, Milwaukee’s manual knockout punch set is priced a bit higher than Greenlee’s comparable Slug-Buster set, model 7238SB. Milwaukee’s set is available for $329, Greenlee’s is ~$290.
The reason for the price difference is because Greenlee’s standard knockout set is rated for use on mild steel, while Milwaukee’s is rated for use on mild steel and stainless steel. The exception is the included 1/2″ punch set, which is only rated for mild steel, but a stainless steel-rated 1/2″ punch set is available separately.
