The Makita GRT01D 40V max XGT Brushless 16 Gauge Rebar Tying Tool Kit (2.5 Ah) is a cordless 16 gauge rebar tying tool built for concrete reinforcement work where speed, tie consistency, and reduced labor matter. This is a rebar tying tool designed for fastening rebar and wire mesh in concrete construction. Model Number: GRT01D. If you are tying steel all day on slab work, bridge work, tilt-up jobs, pool construction, conduit runs, or pre-cast work, this tool is built to do one job fast and do it the same way every time.

The big reason this tool matters is output. Makita rates it for up to 3,600 ties per charge with a 40V max XGT 2.5Ah battery and up to 245 ties per reel on #3 x #3 rebar. That translates to fewer interruptions on large reinforcement layouts. The tool is also engineered to dispense the exact amount of wire each tie needs, which is not just a spec-sheet talking point. On jobs where you burn through reels, controlled wire use can make a real difference in consumable cost over time.

Capacity is where the Makita GRT01D separates itself from lighter-duty tying tools. It handles a minimum tying capacity of #3 x #3 rebar or wire mesh x wire mesh and a maximum tying capacity of #9 x #8 rebar. Makita also calls out deep tying capability, which matters when bar spacing and overlap make access tight. If your work includes larger bar combinations or congested reinforcement, that extra range is the kind of detail that keeps the tool useful across more of the job instead of just a narrow slice of it.

The six tie strength settings give the tool some needed flexibility. Instead of being stuck with one fixed tension, you can match the tie strength to the rebar combination and job requirement. That is useful when you move between lighter mesh work and heavier bar intersections and want control over hold without wasting wire. Makita also states the tool produces up to 65% stronger ties with 16 gauge wire, which points to this being built for crews that need stronger fastening than typical lighter-gauge systems provide.

From a design standpoint, Makita kept the jobsite details practical. The easy-load wire reel design with automatic locking protective cover simplifies reloads and helps protect the reel during handling. A lock-off button helps prevent accidental startup when the tool is being moved around a busy site. There is also a hook that fits up to #6 rebar, which sounds minor until you are working around a mat and need somewhere secure to hang the tool instead of setting it down in mud, slurry, or debris.

The powertrain is brushless and built on Makita's 40V max XGT platform. That matters because this is not a casual-use tool. Rebar tying is repetitive, high-cycle work, and the XGT system is designed around higher-demand cordless applications. Makita also includes Extreme Protection Technology for improved dust and water resistance in harsh conditions, plus digital communication between tool and battery to help manage overload, over-discharge, and overheating. For crews trying to move more concrete work cordless, those system-level protections are worth paying attention to.

As a kit, this version is ready to go with two 2.5Ah XGT batteries, an XGT Rapid Charger, four 16 gauge steel tie wire reels, and a tool bag. That gives a crew a usable starting package instead of just the bare tool. It also makes more sense for first-time buyers getting into the Makita concrete fastening platform, since you can rotate batteries and get to work without piecing together the essentials separately.

Who should buy it? Contractors and crews doing concrete reinforcing work at production volume. That includes commercial building, road and bridge, tilt-up, pool construction, residential foundation work, electrical conduit installation in slab, and pre-cast applications. If you only tie steel once in a while, this is more tool than you need. If tying rebar is part of your daily workflow, the Makita GRT01D is the kind of purpose-built cordless fastening tool that can save real time and reduce hand fatigue across a long day.

Makita GRT01D 40V max XGT Brushless 16 Gauge Rebar Tying Tool Kit means business

This is a serious production rebar tying tool for crews that need cordless speed, stronger 16 gauge ties, and enough capacity to stay useful across a wide range of reinforcement work.

• Who it's for: Concrete crews, bridge and road contractors, tilt-up teams, pre-cast shops, and anyone tying rebar or mesh often enough that hand tying slows the whole job down.
• Why it stands out: The combination of deep tying capacity, up to 3,600 ties per charge, 245 ties per reel, and six strength settings makes it more than a niche tool. It is built to keep moving on real production work.
• Worth knowing: This is a specialized tool with a premium price, so it makes the most sense when rebar fastening is a regular part of your workflow, not an occasional task.

• What type of tool is this? It is a cordless 16 gauge rebar tying tool designed for fastening rebar and wire mesh in concrete reinforcement applications.
• What rebar sizes can it tie? Makita rates it from a minimum of #3 x #3 rebar or wire mesh x wire mesh up to a maximum of #9 x #8 rebar.
• How many ties can it make on one battery charge? It can deliver up to 3,600 ties of #3 x #3 diameter rebar per charge using a 40V max XGT 2.5Ah battery.
• Does it have adjustable tie tension? Yes. It has 6 tie strength settings to match different tension strength requirements.
