The Milwaukee Multi-Size 1/4, 3/8 and 1/2 Replacement Threaded Rod Cutting Die Set was designed to produce clean, burr-free cuts. The superior blade geometry effortlessly cuts through 1/4 in., 3/8 in., 1/2 in. mild steel and 1/4 in., 3/8 in. stainless steel coarse threaded rod, without creating chips or sparks. The 4-sided rotatable threaded rod cutter dies allow users to cut all three sizes of threaded rod with the same tool. Size markings are clearly indicated on all thread cutter dies as well as markings for upper and lower jaw placement. The replacement dies are compatible with the Milwaukee M18 Brushless Threaded Rod Cutter (2872-20) and M18 Brushless Threaded Rod Cutter Kit (2872-21).
