A dependable general purpose tooth for 40 to 48 ton excavators on earthmoving and utility contracts. The 4T5451 keeps a full wear face for most of its life, which matters when machines run double shifts and tooth changes have to be scheduled, not improvised.
Cast in alloy steel and tempered as a whole piece, it holds shape in sandy ground where thinner aftermarket teeth taper off quickly.
