SawStop Technology

Our Patented Active Injury Mitigation (AIM) SAFETY TECHNOLOGY is what makes a SawStop a SawStop

1 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 STOP
- An aluminum brake springs into the path of the blade.
- The blade comes to a complete stop and power to the motor is shut off.
3 DROP
- After the blade comes to a stop, the blade’s angular momentum drives it beneath the table, removing the risk of subsequent contact.
- All of this happens in less than 5 milliseconds.
4 Reset
- Resetting the saw yourself is easy. Simply inspect the blade (and change if damaged) and replace the brake cartridge, and your saw is operational.
- The entire process takes 90 seconds and you’re back to work.

How SawStop Technology Works

At the most basic level, our technology works by continually monitoring a small electrical signal in the saw blade. The human body is conductive so the signal in the saw blade changes when skin makes contact with it. It’s that change to the signal that activates the AIM safety system and engages the aluminum brake.

Two Accidents in One Month

Joe M. (woodworker)

Joe, now retired, worked for 30 years as a general contractor. Joe had two accidents in a one month period doing woodworking as a hobbyist. As result of the accident, he no longer has feeling in the tips of his fingers on his left hand, and his right hand appears deformed.
