The selected tool always depends on the nature of the processing operation. Single- and double-edged tools are used for milling operations with a routing machine.
Single-edged tools permit a variety of setting values and can be simply resharpened. Such tools must be clamped into an eccentric chuck, otherwise chip removal is not possible.
Double-edged tools can be clamped into an eccentric chuck. Only one tool cutter operates and, as in the case of single-edged tools, the knife cutting circle can be variously set. When using a centrical chuck both tool cutters operate and the knife cutting circle remains constant.
Figure 7
(1) Single-edged tool
(2) Double-edged tool
Tools with a taper shank or tap shaft can only be centrically chucked.
Figure 8

(2) Tool with cylinder shank
(3) Tool with taper shank
Why does only one cutter operate during chip removal given the
eccentric cucking of a double-edged
tool?
