Bluetooth® lithium-ion (Li-Ion) battery with tabless cell technology and AIRSTREAM cooling

TBX 8 Tabless Battery

When the job demands more, the TBX 8 delivers. With 8.0 Ah capacity and tabless
cell technology, this is the most powerful and longest-running battery in the Festool
system—built for high-demand tools like saws and dust extractors. Tabless technology
reduces internal resistance, delivering more usable power with less heat. That
means longer runtime, consistent performance under load, and faster charging. With
AIRSTREAM technology, the battery is actively cooled during charging—so it’s ready to
go again in as little as 25 minutes with the SCA 16 rapid charger. Bluetooth® connectivity
adds even more control. Automatically start a paired Dust Extractor when the tool
powers on, or use the Festool app to monitor charge level, temperature, and usage data.
From heavy-duty cutting to continuous extraction, the TBX 8 keeps you working longer—
with the power to get through the toughest tasks.

Maximum runtime for demanding tools
Run longer and stronger on high-demand applications with 8.0 Ah capacity delivering extended runtime and consistent power for tools that need it most.
More power with less heat
Work longer with less downtime as tabless cell technology reduces heat and internal resistance for longer battery life and faster charging.
Connected and ready
Stay efficient and in control on the job with Bluetooth® enabling automatic dust extractor start and providing real-time battery data through the Festool app.
