Joint cutter

Piranha Cutter

Item no. 90200

Rokamat Chameleon


  • Milling of hard joints
  • Cutting of cable slots


  • Low vibration
  • Almost dust-free renovation of joints
    (fine dust / particulates only 0.25 mg/m³)
  • Fatigue-free operation due to light weight hand tool (approx. 1.7 kg)
  • Motor separated from cutting device -> longer motor life
  • Robust aluminum housing


The joint cutter Piranha Cutter is the right choice for the renovation of hard joints.

The 1 500 W motor and the up to 9 100 min-1 of the diamond cutting discs provide plenty of traction - whereas machines from other manufacturers sorely lack the power. Successfull joint renovation (e.g. of clinker facades or swimming pool tiles) or cable slot cutting is guaranteed - without exertion.

The robust aluminum housing has been carefully designed to ensure an almost dust-free milling process. The Piranha Cutter is recommended by the European Federation of Building and Wood Workers for low dust generation during work.

The sophisticated handhold of the joint cutter provides significant additional value. Firstly, it allows a good view upon the working area. Secondly, the built-in anti-vibration buffer makes work much more pleasant compared to conventional joint milling machines.

Another factor that contributes to working comfort is the separation of motor and hand tool. The motor can be carried on a belt or shoulder strap, which not only makes the machine very light weight (hand tool 1.7 kg), but also increases the service life of the motor.
