There are four types of concretor’s nippers and pliers available. These are the standard manual concretor’s nipping pliers, high-leverage manual nipping pliers, rotary tying pliers and electrically-powered rebar tying machines.
Standard concretor’s nipping pliers
These are the most common type of concretor’s nippers and pliers. They are particularly suited to the DIYer or trades person who only occasionally needs to tie steel reinforcing bars together.
These are the least expensive type of concretor’s nippers and pliers and have a wide range of features available, including polished jaws, black phosphate, chrome- or nickel-plated surface finishes and PVC or bi-material handles.
ADVANTAGES
DISADVANTAGES
Least expensive type of concretor’s nippers and pliers
Manually operated so require no external power supply or charging
Available with either bi-material or PVC handles
Requires more user effort than other types
Has a smaller cutting capacity than high leverage concretor’s nippers and pliers
High-leverage concretor’s nipping pliers
These are a larger version of the standard concretor’s nippers and pliers. Not only are the handles longer but the jaws are a shorter distance from the pivot bolt. These two factors greatly increase the leverage that can be applied, making cutting through thick tying wire easier than with other types.
They also share many of the same features as standard concretor’s nippers and pliers. However, bi-material handles are not available on this type.
ADVANTAGES
DISADVANTAGES
Less effort required than with standard concretor’s nipping pliers
Manually operated so require no external power supply or charging
Less expensive than electrically powered rebar tying machines
Have the largest cutting capacity
More expensive than standard concretor’s nipping pliers
Not available with bi-material handles
Rotary tying pliers
This type of concretor’s nippers and pliers is designed to both speed up the process of tying rebar together with wire and reduce the fatigue and muscle strain on the user. It does this with the use of a rotary handle. With the wire tie clamped in the jaws, pulling the rotary handle spins the tool around, quickly twisting the wire.
This eliminates the twisting movement in the wrist that is required with other manual concretor’s nippers and pliers.
ADVANTAGES
DISADVANTAGES
Manually operated so require no external power supply or charging
Less expensive than electrically powered rebar tying machines
Quicker at tying rebar than other manual concretor’s nippers and pliers
Causes less fatigue and wrist stain than other manual concretor’s nippers and pliers
More expensive than other manual concretor’s nippers and pliers
Has a smaller cutting capacity than high leverage concretor’s nippers and pliers
Not readily available outside the U.S.
Electric rebar tie machine
These tools are capable of tying wire around rebar in just 0.8 seconds, making them the quickest way of securing rebar. They also don’t require twisting movement of the user’s wrist, so they cause less strain and fatigue than manual concretor’s nippers and pliers. However, they do weigh more than manual types at around 2kg.
They also cost considerably more than manual concretor’s nippers and pliers, making them only suitable for professional concretors who are regularly tying a lot of rebar together.
ADVANTAGES
DISADVANTAGES
Much quicker than using manual concretor’s nippers and pliers
Tie tension of wire can be adjusted
Cause far less user fatigue than manual concretor’s nippers and pliers
