Rebar Tying Tool FAQ

General

A battery powered rebar tier is a cordless handheld tool that ties rebar electronically. Re-Bar-Tiers are typically used in concrete construction to prevent rebar from shifting when concrete is poured. Compared to the conventional method of tying rebar, with hand tie wire and pliers, rebar tying tools make tying rebar faster, more efficient and more cost effective. MAX invented the original battery powered rebar tying tool in 1993 and currently has developed various rebar tying tools for various applications.
To use a battery powered rebar tying tool, insert the tool mouth into a rebar cross section and pull the trigger. This action dispatches MAX proprietary wire, which should be loaded into the magazine of the tool before use. Once the wire loops around the rebar, the tool’s twisting unit grabs and twists the wire to form a tie, before finally cutting the wire to release it from the tool.
New or less experienced rebar tying workers are able to quickly learn how to use the rebar tying tool. Extensive training is not required. It takes approximately 5 minutes to learn how to load a wire and form a tie. MAX recommends reading the tool manual before use to understand how to safely operate it.
For many years MAX rebar tying tools have been used worldwide by large contractors. Rebar tying for most projects requires the rebar not move when the concrete is poured, which is exactly what MAX rebar tying tools are designed to do. If you’re asked to submit wire specifications to the project engineer, contact MAX at 1-800-223-4293 for details.
The TWINTIER is a revolutionary rebar tying tool that has innovative mechanisms which allow it to tie faster, tighter and produce a shorter profile tie than previous Re-Bar-Tier tool models. The TWINTIER is also more cost efficient due to the lower consumption of wire per tie. The RB441T, a 6th generation MAX Re-Bar-Tier, was the first "TWINTIER". The 2nd TWINTIER, the RB611T, can tie the largest rebar combinations of any battery powered rebar tying tool on market. The RB611T is able to tie up to #9 x #10 rebar, depending on the rebar manufacturer. For more details on MAX TWINTIERs, please visit: www.twintier.global/us-en/

Wire

MAX manufactures annealed black steel, poly-coated annealed, electro-galvanized, Buy America steel and stainless-steel tie wire. Stainless steel wire is a special order item. If you require stainless please contact at MAX at 1-800-223-4293.
MAX rebar tying tools use proprietary MAX tie wire reels. Traditional MAX Re-Bar-Tier series tools use the 21ga. TW898 tie wire and the TWINTIER tools use the 19ga. TW1061T wire. Generic wire cannot be used with MAX rebar tying tools. For details on our wire platforms, please see the MAX product webpage (Click here for details).
No. All MAX rebar-tiers require proprietary MAX tie wire reels in order to work. 16 ga. or 16.5 ga. bulk hand tie wire is not compatible with any MAX rebar tying tool.
No. MAX RB218/398/518 use the 21 ga. TW898 series tie wire. MAX TWINTIERs (RB441T/RB611T/RB401TE) use the 19 ga. dual stranded TW1061T series wire. You cannot use TW898 series wire in TWINTIER tools and you cannot use TW1061T TWINTIER series wire in any 21 ga. tools, such as the RB398S. However, the batteries used with these tools are compatible. If you are looking to upgrade your RB398S tools to the new TWINTIER, MAX offers RB441T tools that do not have batteries or chargers included for a cost-efficient upgrade.
Yes, USA made steel black annealed wire is available. Mill certification is also available to download on our website (Click here for details). To download mill certs, create a log in for the MAX mill cert download page and enter the serial number of the USA made MAX wire. You can download the mill certs using the specific serial number up to 3 times. If any other assistance is needed please contact your local MAX dealer.
The capacity of a tie wire spool differs depending on the type of tie wire and the tool model being used. The 21 ga. TW898 series wire tying tools are able to tie between 75 and 210 ties per spool. The 19 ga. TW1061T TWINTIER wire series is able to tie between 115 and 265 ties per reel. The 16 ga. TW1525 series tie wire is able to tie from 120 - 230 ties per reel.

Operation

After loading the appropriate MAX tie wire spool into the tool's magazine, simply turn the tool on and insert the tool mouth into the rebar cross section at a 45° angle. Depending on the tool series, each model will have a different optimal position for tying. Once the rebar cross section is in place, pull the trigger and the tool will tie the rebar automatically. For information on how to load wire for each tool and where the optimal tying position is located, please see the owner’s manual accessible from the product pages here (Click here for details).
After a day of work, wipe down the tool with a piece of cloth to remove any moisture and clean away any debris surrounding the tool mouth and feeding gears. We do not recommend using the tool in the rain. Rust on the wire can cause the tool’s feeding gears to wear faster than designed. Do not use any degreasing solutions such as WD40 to clean the tool. This can cause grease build-up on the internal parts which will lead to serious operational issues.
MAX rebar tying tools use proprietary MAX tie wire reels. Traditional MAX Re-Bar-Tier series tools use the 21ga. TW898 tie wire and the TWINTIER tools use the 19Ga TW1061T wire. Generic wire cannot be used with MAX rebar tying tools. For details on our wire platforms, please see the MAX product webpage (Click here for details).
No. All MAX rebar-tiers require proprietary MAX tie wire reels in order to work. 16 ga. or 16.5 ga. bulk hand tie wire is not compatible with any MAX rebar tying tool.
Both 19ga. and 21ga. rebar tying tool platforms operate on the 14.4 V MAX battery. The RB655 uses the MAX Ni-MH 9.6V battery. Use of a non-MAX battery or tie wire may result in service issues, so please use MAX wire and batteries to ensure best tool performance.
All MAX rebar tying tools go through an initiation process when turned on. This initiation adjusts the wire position and repositions the internal twister so that the tool is ready to tie. By turning the tool on and off the tool will cut off the wire for you. If a TWINTIER has a jam, simply face the tool towards the ground then turn the tool off and then back on. The initialization process should self-clean the jam.
