Abstract
A chisel holder is connected exchangeably in a fixed manner to at least one base mount disposed on a surface of a cylindrical cutting device, such as a cutting machine or a line milling machine, in a manner obviating use of a threaded setscrew. A borehole extends through the base mount, and a securing bolt received therein grips at least regionally through or behind an aligned recess formed in the chisel holder. The securing bolt is then clamped or locked to the base mount without use of threads.
