The KYA-590 Automatic Electric Rebar Tying Tool is a handheld battery-powered tool for automatic rebar tying in construction applications. The current KYA specification lists a tying range of 8–34mm, 0.8-second tying speed, 12.8V 2.2Ah battery and more than 1,500 ties per charge.
KYA-590 uses 0.8mm tie wire and the current product page specifies 2 wraps per tie. Published applications include civil building construction, steel-bar reinforcement, floor pipe work, heating-floor mesh and concrete foundation work.
For purchasing and wire selection, use the exact KYA-590 tool specification rather than assuming compatibility with wire reels designed for MAX, TJEP, Makita or other rebar tying systems. Wire diameter alone does not establish reel or feed compatibility.

Wire-length data note: the current KYA-590 page contains two different reel-length values: 100m in the top product specification and 110m in the detailed specification. This page should not present either value as definitive until the current KYA-590 reel specification is confirmed.
KYA-590 is designed to automate repetitive tie-wire fastening around reinforcing steel and related reinforcement assemblies. The operator positions the tool around the required joint and activates the tying cycle with the trigger.
The current KYA page identifies applications including civil construction, steel-bar reinforcement, floor pipe installation, heating-floor mesh and concrete foundation work.
The current KYA-590 product specification publishes a tying range of 8–34mm. This value should be used exactly as published rather than converted into specific U.S. rebar combinations that the current page does not identify.
Different rebar-tier manufacturers describe capacity differently. Some publish combined bar configurations such as #3 × #3, while others publish a total workpiece-thickness range. When evaluating KYA-590 for a specific reinforcement joint, provide the actual bar or mesh dimensions rather than assuming that another manufacturer's capacity notation is directly equivalent.
KYA currently publishes a 0.8-second tying speed per knot for the KYA-590. This is the product-page speed specification and should be kept separate from competitor tie-speed claims because tying mechanisms, wire systems and test conditions vary by tool.
For production planning, actual output will also depend on operator positioning, wire replacement, battery changes, reinforcement geometry and jobsite conditions.
The KYA-590 uses a published DC 12.8V, 2.2Ah battery. The current product page states approximately 90 minutes for charging and more than 1,500 ties per charge.
Ties-per-charge values should be treated as the published KYA product specification rather than a guaranteed jobsite output. Actual battery output can vary with tie conditions, temperature, battery condition and operating pattern.
The current KYA-590 specification requires 0.8mm tie wire. The product description identifies the wire as low-carbon steel and specifies two wraps per tie.
Do not select replacement tie wire by diameter alone. The reel dimensions, hub design, wire feed path, wire condition and coil format must also match the KYA-590 tying mechanism.
The current product page is internally inconsistent. The top specification states 100m, while the detailed specification table states 110m / 360ft.
Because reel compatibility depends on more than total wire length, buyers should confirm the current KYA-590 reel part and loaded wire specification before purchasing replacement coils in volume.
| Current Source Location | Published Value | How to Use It |
|---|---|---|
| KYA-590 Top Product Parameters | 100m | Treat as one current KYA page value pending specification confirmation |
| KYA-590 Detailed Specifications | 110m / 360ft | Treat as a conflicting current KYA page value pending specification confirmation |
The KYA-590 page specifies 2 wraps per tie. The detailed table also lists a published wire consumption of approximately 300–500mm per knot.
Wire consumption varies with the size and geometry of the joint, so the 300–500mm figure should be treated as KYA's published range rather than converted into a fixed ties-per-coil number without the corresponding reel specification and test conditions.
Automatic rebar tying tools are not one universal consumable system. Current professional tools on the market use different wire gauges, reel formats, jaw capacities, battery systems and tying mechanisms.
| Selection Parameter | KYA-590 Reference | Why It Must Be Checked |
|---|---|---|
| Tying Range | 8–34mm published by KYA | Other manufacturers may express capacity as combined rebar sizes rather than one millimeter range |
| Wire Diameter | 0.8mm | Other current tools use different wire gauges and cannot be cross-referenced from diameter alone |
| Reel Format | KYA-590 reel system | Hub, spool geometry and feed design must match the tool |
| Wraps | 2 wraps | Different tying mechanisms can use different numbers of wires or wraps |
| Battery | 12.8V, 2.2Ah | Battery platforms and chargers are tool-specific |
| Tie Speed | 0.8 sec per knot | Competitor speed figures may use different tying mechanisms and test conditions |
Compatibility note: do not describe KYA-590 as compatible with MAX TWINTIER, TJEP, Makita or another manufacturer's wire reel or battery merely because the tools perform the same general rebar-tying function.
The current product page lists civil building construction as a primary application for automatic tying of compatible reinforcing-steel joints.
KYA-590 can be used for repetitive steel-bar tying where the reinforcement joint falls within the tool's published 8–34mm tying range.
Floor pipe reinforcement is listed on the current KYA page. Confirm the actual workpiece dimensions before selecting the tool for a specific pipe-and-mesh arrangement.
Heating-floor mesh installation is another published application. The tying range and joint geometry should be checked against the mesh and reinforcement configuration used on the project.
The current KYA page also identifies concrete foundation work as an application for automatic rebar tying.

KYA-590 is a handheld automatic electric rebar tying tool designed to tie compatible reinforcing-steel and mesh joints using 0.8mm tie wire.
The current KYA product page publishes a tying range of 8–34mm. The page does not provide a complete individual-bar combination chart, so use the actual joint dimensions when checking a specific application.
The current published specification is 0.8 seconds per knot.
KYA lists a DC 12.8V, 2.2Ah battery for the KYA-590.
The current KYA-590 page publishes an approximate charging time of 90 minutes.
KYA currently publishes over 1,500 ties per charge. Actual output can vary with operating conditions and battery condition.
The current specification uses 0.8mm tie wire.
The current KYA page contains conflicting information: the top parameter list says 100m, while the detailed specification says 110m / 360ft. Confirm the current production reel specification before ordering wire.
The current KYA-590 product specification lists 2 wraps per tie.
The detailed KYA specification lists approximately 300–500mm of wire per knot. Actual wire use depends on the tied joint.
The current KYA product page lists a weight of 2.5kg / approximately 5.5 lbs.
The current KYA-590 page does not establish compatibility with MAX TWINTIER reels. MAX's current TwinTier systems use their own 19GA wire products and reel system. Do not assume compatibility from the general rebar-tying application alone.
No compatibility conclusion is supported by the current KYA page. TJEP products use model-specific wire systems, so reel and wire specifications must be compared before substitution.
The current page lists civil building construction, steel-bar tying, floor pipe reinforcement, heating-floor mesh installation and concrete foundation work.
The current troubleshooting table identifies two long beeps as a low-battery warning and four short beeps as a high-temperature warning.
The current KYA troubleshooting data says to check whether the curl guide is fully closed, whether the reel is empty or caught and whether the cutter or wire-feed area is blocked.
Provide the exact KYA-590 tool model and confirm 0.8mm wire, reel dimensions, hub geometry and current coil-length specification before purchasing replacement reels.
The PDF currently linked from the KYA-590 product page lists KYA-210B and KYA-400B in its technical-parameter section rather than KYA-590. Confirm the correct KYA-590 manual before applying model-specific technical values from that document.
KYA-590 is positioned for construction-tool distributors, reinforcement contractors, concrete-product operations and other professional users requiring an automatic rebar tying system.
For quotations, provide the required tool quantity, actual reinforcement sizes, intended application and tie-wire requirement. If replacement wire is also required, confirm the current KYA-590 reel specification rather than relying only on the 0.8mm wire diameter.
