Abstract: Mechanical sensor for stopping the operation of a cutting tool in the event of tool bit breakage, in which a pivotable tip is carried by a tool holder with its lower extremity adjacent the tip of the cutting bit. A spring releasably urges the pivotable tip in a given direction, and a rod carried by the holder with one end thereof engaged with the tip and movable in response to pivotable movement thereof. A spring urging said rod into engagement with the tip, the opposite end of the rod being positioned to actuate a switch to cut off the power to said cutting tool.
