This rebar cutter is a work and back saver. It cuts #4 Grade 60 rebar with ease and little deformation. I tried cutting the rebar manually. I purchased a 42 inch HD bolt cutter from Harbor Freight, it was the biggest one they sell. With two men working the bolt cutter, it barely made a mark on the rebar. This rebar cutter quickly paid for itself eliminating trips to the Chiropractor and doctor. LOL! I'm cutting a lot of #4 rebar so I got the model a step up from the cutter rated for cutting #4 rebar. I recommend buying the rebar cutter at least one step up from the rating of the size of rebar you plan on cutting. I almost wish I purchased the biggest rebar cutter but this one is doing a fantastic job so far. Be advised that the operator manual is not written very well.
