ABSTRACT:
A centrifugally operated clamping device for clamping a reversible blade insert in a planing tool ensures positive engagement between the clamp and the blade. The clamping device includes a clamping wedge which has an inverted T-shaped cross-section and is positioned in a similarly configured groove in the tool. The wedge is biased relative to the bottom of the groove so that the clamp will be easily disconnected from the blade.
