A heavy-duty aluminum brake stops the blade.
The blade stops within milliseconds of detecting contact, quicker than a car airbag deploys.
During this time three things happen:
- An aluminum brake springs into the spinning blade, to stop the blade.
- The blade’s angular momentum drives the blade beneath the table, removing the risk of subsequent contact.
- Power to the motor is shut off.
Resetting the saw is easy. It takes about five minutes to replace the $69 single-use brake cartridge and blade.
