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.
“When something goes wrong, you simply can’t move faster than a spinning blade.”
“I’m not whole anymore. I had a part of me that…I don’t have anymore. And I can’t get it back”
SawStop
Patrick Callahan was working at his stone and countertop production business in 1998, cutting Corian (a synthetic material used for countertops) on a contractor-style table saw—without the blade guard in place—for a custom job. Unfortunately, the Corian rode up on the blade, then snapped back down and shattered, pulling Patrick’s left hand—his dominant hand—into the Read more…
Table Saw Accident Victims
These woodworkers have honored us with their stories. Please take a moment to listen.
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.
Amputation of Finger
Brandan S.(hobbyist)
“It flung my finger. I couldn’t turn the saw off because I was in shock.”
Amputation of Multiple Fingers
Nick C.(hobbyist)
“I’ve been doing this for years and never been hurt. That evening I spent 14 hours in surgery.”
Amputation of Finger
Tristan(woodworker)
“You only have a split second between having your finger and not having your finger.”
