We carry three lengths of bit extender. All have lobed shanks to interlock and prevent slippage in the chuck; a simple insert-and-twist action holds securely yet allows quick changes. The lobed shanks also interlock with the three sizes of Morse taper adapters we offer, allowing you to mount any of the extenders directly in a lathe.
Patented. Made in France.
Note: The 1/2" maxi-cut Forstner bit cannot be used with the bit extenders.
