NBT ER | No Drive Dogs

NBT Tool Holders from EMG Precision. NBT Tool Holders are exactly the same as BT Shanks, with the exception of the Drive Dogs. Sometimes referred to as Key-Ways, these features are not present on NBT Tool Holders. These are often used on automatic tool change spindles that do not support indexxing though the use of a spindle encoder. This allows NBT Tool Holders to be collected by an ATC System regardess of its rotary position.
