The RT545 electric rebar tying tool is an 18.5V, 5th-generation cordless rebar binder built to handle a wide range of bar — up to around 45mm — at speed.
What the RT545 does
It's a powered, automatic rebar tier. Position the head, pull the trigger, and the 18.5V tool feeds, wraps and twists the wire in one motion. The wider tying range makes it suited to heavier structural work as well as everyday slabs.
Why it stands out
- Wide tying range: handles roughly 4–45mm rebar, covering light through to heavy cages.
- 18.5V power: strong, consistent twisting for reliable ties.
- Speed and consistency: sub-second ties with even tension every time.
- Less fatigue: saves hands, wrists and back over a long shift.
Who it's for
Steel fixers and contractors who tie a mix of light and heavy rebar and want one tool that covers the range.
