Product Highlights

  • Increased power output.
  • High output with low weight.
  • Smart connectivity with Bluetooth® and the Festool app.
  • TBX batteries with tabless cell technology deliver higher power transfer with less heat buildup—resulting in stronger performance, longer runtime, and extended battery service life for demanding cordless applications.
  • The TBX 4 Compact Battery delivers impressive power in a lightweight, well-balanced design. At just 600 g, it provides high output without added bulk, making it ideal for medium- to high-demand applications where control and handling matter.
  • Integrated Bluetooth® technology automatically starts a paired Festool dust extractor when the cordless tool is switched on. With the Festool app, users can monitor detailed battery information including charge level, temperature, and charge cycles—keeping performance transparent and predictable.

Features and Benefits

  • Maximum output when it counts. Advanced tabless cell technology delivers strong, consistent power—even for demanding applications—by improving energy flow and reducing internal resistance.
  • Lightweight power for reduced fatigue. 4.0 Ah capacity delivers full power at just 1.3 lbs (600 g), helping reduce fatigue during extended use without sacrificing performance.
  • Extended battery service life. Lower heat generation reduces stress on the cells, helping extend overall battery lifespan and maintain performance over time.
  • Reliable performance in tough conditions. Tabless Battery design maintains dependable output in both hot and cold environments, keeping tools ready across a wide range of jobsite conditions.
  • Faster recharge cycles. Low heat buildup allows the battery to be recharged immediately after use, minimizing downtime between tasks.
  • Smart battery management. When used with the Festool app, Bluetooth® functionality provides access to detailed battery data including charge level, temperature, and charge cycles.
  • Clear charge status at a glance. Integrated LED indicators display the current charge level anytime, so you always know when you’re ready to work.
  • Stable, tool-protective design. Soft-touch perimeter protects the tool and provides a secure resting surface, even on sloped or uneven work areas.
  • Backed by Festool Service. Covered by Festool Service for stress-free ownership and long-term reliability.
  • Rapid AIRSTREAM charging. When used with the AIRSTREAM SCA 16 quick charger, active cooling enables recharge times of approximately 25 minutes, getting the battery back to work faster.
  • Automatic dust extraction start. Bluetooth® connectivity automatically starts a paired Festool CLEANTEC dust extractor when the cordless tool is switched on.
