The KYA-660B uses an 18V 5.0Ah Li-ion battery and can complete over 4600 ties per charge. The battery charges in approximately 70 minutes, helping reduce downtime on continuous construction projects. For large jobsites, spare batteries and sufficient tie wire stock are recommended to maintain productivity.
| Advantage | How It Helps Construction Teams |
|---|---|
| Higher Productivity | 0.6-second tying speed helps complete repetitive rebar tying work faster than manual tying. |
| Reduced Labor Fatigue | Battery-powered one-hand operation helps reduce wrist, arm and back strain during long tying tasks. |
| Consistent Tie Quality | Automatic tying improves tie consistency across repeated rebar intersections. |
| Lower Wire Waste | Wire pull-back mechanism reduces unnecessary wire use and helps lower consumable cost. |
| Compact Tie Height | Shorter tie height can help reduce concrete cover requirements in suitable applications. |
The KYA-660B automatic rebar tying tool is suitable for reinforced concrete projects where large numbers of rebar intersections must be tied quickly and consistently. It is especially useful for contractors, precast factories and infrastructure construction teams.

The KYA-660B is designed for one-hand operation. Load the 1.0mm twin wire coil into the quick-load magazine, use the push gear release to feed the wire, position the tool over the rebar intersection and press the trigger to complete a tie in approximately 0.6 seconds. Always read the tool manual and follow safety requirements before operation.
