Increased safety against severe cuts thanks to an intelligent cartridge. Quick replacement of cartridges with just a few simple steps. There are approximately 4,000 injuries from circular saws each year, which equates to 16 injuries per workday. About 26% of serious accidents result in a disability pension. With the TKS 80 table saw, the risk of severe cuts is reduced. Upon skin contact, the cartridge releases a pre-tensioned spring that shoots an aluminum block into the saw blade. After activation, the cartridge can be replaced with just a few simple steps.
