SawStop Video Demos

Protect your fingers and those of the people you care about. This Table saw system will stop a running blade in less than .1 second after it contacts a human body part. This demo uses a hot dog for the demonstration.

SawStop in Slow Motion

This is a slow motion video of the SawStop system in action. You can see in the lower right corner the time it takes to stop the saw and move it out of the way (.00150 seconds).

Why SawStop?

This 8-minute video will show some testimonials and other information pertinent to this amazing saw! This is a large file and will take some time to download, but is well worth the time. Windows Media Player is required.

Every year in the United States there are tens of thousands of serious injuries on table saws. These injuries change people’s lives and they cost society billions of dollars in medical expenses, lost wages, worker’s compensation, increased insurance rates, lost productivity, etc.

The US Consumer Product Safety Commission reports that every year table saws are involved in:

•		Over 60,000 injuries
•		Over 3,000 amputations
•		$2 billion in injury-related costs

That's One Injury Every 9 Minutes!

SawStop saws are designed to address this risk. Every SawStop saw includes revolutionary new technology to detect when an accident occurs and stop the blade in milliseconds.

The SawStop safety system includes an electronic detection system that detects when a person contacts the blade. The system induces an electrical signal onto the blade and then monitors that signal for changes. The human body has a relatively large inherent electrical capacitance and conductivity which cause the signal to drop when a person contacts the blade. Wood has a relatively small inherent capacitance and conductivity and does not cause the signal to drop.

This drawing below shows the changes in the electrical signal when a finger touched the teeth of a spinning saw blade during an actual test.

The line represents the electrical signal that dropped quickly when the blade touched the finger. The dips in the signal line illustrate the changes in the electrical signal that were detected as two successive teeth touched the finger. When the detection system sees dips like these, it knows a person has touched the blade.

A fast-acting brake stops the blade when contact is detected. The brake includes a heavy-duty spring to push a block of aluminum, called a brake pawl, into the teeth of the blade to stop the blade from spinning. The spring is held in compression by a fuse wire until contact is detected. When contact is detected, the system sends a surge of electricity through the fuse wire to burn the wire and release the spring. The spring pushes the brake pawl into the teeth of the spinning blade, and the teeth cut into the aluminum and bind, thereby stopping the blade. All this happens in about 3–5 milliseconds, or 1/200th of a second. At the same time, the angular momentum of the blade causes the blade to retract below the table and the power to the motor is shut off.

The brake mechanism is shown in the drawing to the right. The arrow shows how the aluminum brake pawl pivots into the teeth of the blade. The brake pawl is part of a replaceable cartridge that includes the spring, fuse wire and electronics necessary to burn the fuse wire. An optional dado cartridge provides the same protection for dado cuts.

The standard and dado brake cartridges are single-use components that must be changed if the brake is ever activated. Changing a brake cartridge is fast and easy, no more complicated than changing the blade.
