In a pinch, it’s possible to create small-diameter bends in rebar by pulling it around a piece of pipe, but that can get old fast if you’re dealing with a whole house foundation’s worth of it. Hitachi’s VB16Y rebar cutter/bender makes the whole process a lot easier.
When you place a piece of rebar in the VB16Y (perpendicular to its handle) and squeeze the trigger, its electric motor drives a small rotary table via reduction gears to bend the ‘bar around the table’s central vertical rod. You can pre-set the amount of bend, and detents make it easy to set 45, 90, 135, and 180 degree bends.
The VB16Y can also cut ‘bar up to #5 (5/8″) ‘bar, and it features a slip clutch for overload protection.
It’s not cordless, but it still looks like it’d be pretty simple to carry the VB16Y around the job site to bend where needed. Street pricing starts around $2,000.
