Bosch has announced a new jobsite table saw that includes flesh detecting technology to protect the saw operator from accidents. The new saw is the first commercially viable saw to directly complete with SawStop in the safety saw arena.
Officially designated the Bosch GTS104A REAXX portable jobsite table saw, the new tool features what Bosch describes as proprietary Active Response Technology. The system detects human flesh that comes in contact with the blade and drops the saw blade below the tabletop. Bosch says the new system is also designed to save the user from injury without damaging the blade.
Fast reset after actuation
Early reports suggest the saw makes use of technology from the auto industry that is used for air bags in cars. An activation cartridge for the safety device is designed to hold two charges, so a single cartridge allows activation for two incidents. In case of activation, the system can be reset in less than 60 seconds and requires no blade replacement, according to Bosch. After two activations, the cartridge must be replaced. All necessary parts, instructions and wrenches are located onboard the saw, including storage for extra activation cartridges. After 25 actuations of the safety system, the saw must be returned to Bosch for servicing.
The competing SawStop system works by simultaneously dropping the blade below the saw table and stopping the blade’s rotation with an aluminum block that is rammed into the blade. The safety cartridge must be replaced after every use, and the blade stopping mechanism likely means the saw blade must be replaced, as well.
