Fisch 150mm Extension For 12mm Shanks

An extension for Forstner bits and similar boring bits with 12mm shanks. The extension enables you to bore to a greater depth whilst still maintaining rigidity. The overall length is 150mm, giving an effective extra 120mm of depth of cut. Two grub screws ensure a secure fixing of the shank of the Forstner bit. Made in Austria. Note: Due to the diameter of the extension this is suitable for cutters 22mm diameter and above.
