Back Boring

Through the use of standard components, BIG KAISER boring heads have the flexability to additionally perform back boring opporations. In some instances a new insert holder is required, but for most, users can simply reverse the existing insert holder.

Please note: We have decided to change our tool connection description of KA/KAB to CK/CKB to be consistent with how the product is referred to globally. There is absolutely zero geometric difference between a tool marked KA/KAB and CK/CKB, it was simply a way to differentiate North American inch tools from metric tools sold throughout the rest of the world.
