How Safe is a Sawstop Saw? - Never Before Seen 19,000

SawStop Saws Detect Contact With Skin

The blade carries a small electrical signal, which the safety system continually monitors. When skin contacts the blade, the signal changes because the human body is conductive. The change to the signal activates the safety system.

How It Works

​1. Monitor & Detect

• The blade carries a small electrical signal.
• When skin contacts the blade, the signal changes because the human body is conductive.
• The change to the signal activates the safety system.

​2. Brake Activation

• An aluminum brake springs into the spinning blade, stopping it.
• The blade’s angular momentum drives it beneath the table, removing the risk of subsequent contact.
• Power to the motor is shut off.

All this happens in less than 5 milliseconds!

​3. Reset

Resetting the saw yourself is easy. Simply replace the blade and affordable brake cartridge and your saw is operational. The entire reset process takes less than five minutes.
