Makita GRT01Z 40V max XGT Brushless 16-Gauge Rebar Tying Tool

The Makita GRT01Z 40V max XGT Brushless 16-Gauge Rebar Tying Tool is a cordless rebar tying tool built for faster, more consistent tying on reinforcing steel. This is a rebar tying tool designed for fastening rebar intersections and wire mesh in concrete and structural work. Model Number: GRT01Z. If you spend your day on slab work, bridge work, tilt-up, pre-cast, conduit runs, or pool steel, this is the kind of tool that cuts hand-tying time and helps keep your pace up.

What matters most here is capacity and output. This tool ties 16 gauge wire and handles a wide range of combinations, from #3 x #3 rebar up to #9 x #8 rebar, with support for wire mesh to wire mesh tying as well. Makita also rates it for up to 65% stronger ties with 16 gauge wire. On the job, that means this is not just about speed. It is also about getting a tighter, more consistent tie across a broader range of assemblies than lighter-duty tying tools can manage.

Runtime is another big selling point. Makita states up to 3,600 ties of #3 x #3 diameter rebar per charge when used with a 40V max XGT 2.5Ah battery, and up to 245 ties per reel of #3 x #3 rebar. For crews trying to keep production moving, that translates into fewer stops for battery swaps and fewer reel changes during repetitive tying work. It is also designed to dispense the exact amount of wire each tie needs, which matters because wasted wire adds cost over a long day and over the life of the tool.

The GRT01Z is built around Makita's brushless motor platform, which is the right call for a tool that gets used in repeated cycles under load. Brushless design helps with efficiency, run time, and long-term wear. Makita also gives you six tie strength settings, so you can match tension to the application instead of being stuck with one output level. That is useful when job conditions, material stack-up, or inspector expectations call for a little more control.

Makita also paid attention to day-to-day usability. The easy-load wire reel design with automatic locking protective cover makes reloads more straightforward, which is exactly where production tools should save time. A lock-off button helps prevent accidental start-up, and the side hook fits up to #6 rebar for jobsite storage. Those are small details until you are working around steel all day, then they start to matter a lot.

For rough site conditions, this tool includes Makita Extreme Protection Technology, which is engineered for improved dust and water resistance. It also benefits from the XGT platform's digital communication that monitors and protects against overload, over-discharge, and overheating. That is important on a high-demand cordless fastening tool because repeated cycling can create heat and battery strain fast. The system is designed to manage that load instead of just hoping the operator backs off in time.

System fit is clear. The GRT01Z is part of the Makita 40V max XGT platform and is compatible with Makita 40V max XGT lithium-ion batteries only. If you are already on XGT, this tool makes a lot more sense because you can keep batteries and charging in one system. If you are not, this is still a serious production tool, but remember this version is tool only, so battery and charger are not included.

Who should buy it? Contractors and crews doing concrete reinforcement work, commercial building, road and bridge, tilt-up, pre-cast, pool construction, and electrical conduit installation are the obvious fit. Serious users who tie rebar daily will get the value fastest because the speed, tie consistency, deep capacity, and lower wire waste all pay back where repetition is high. If you only tie steel occasionally, it may be more tool than you need. If rebar tying is regular work, this is exactly the kind of tool that earns its keep.

A serious production tool for serious steel work

The Makita GRT01Z 40V max XGT Brushless 16-Gauge Rebar Tying Tool makes the most sense for crews that tie rebar every day and want more capacity, better consistency, and less wasted motion.

• Who it's for: Concrete, pre-cast, tilt-up, bridge, and pool crews that need a cordless rebar tying tool for repeated fastening work.
• Why it stands out: Deep tying range, 16 gauge wire strength, up to 3,600 ties per charge, and six strength settings make it more than just a convenience tool.
• Worth knowing: This is a tool-only version, so plan on adding an XGT battery and charger if you are not already on the platform.

• What battery platform does this tool use? It is compatible with Makita 40V max XGT Lithium-Ion batteries.
• What rebar sizes can it tie? Makita lists a tying capacity range from #3 x #3 up to #9 x #8 rebar, with wire mesh to wire mesh capability as well.
• How many ties can it make per charge? Makita rates it for up to 3,600 ties of #3 x #3 diameter rebar per charge with a 40V max XGT 2.5Ah battery.
• Can tie tension be adjusted? Yes. It has six tie strength settings to match different tension strength requirements.
