HL TAB Bit
When the HL TAB pilot bit is attached to a 3" self feed bit, it becomes the full HL TAB installation piece. The HL TAB pilot bit is the 1.5" guide to keep the 3" self feed bit on track in the proper manner. You can choose to buy the HL TAB pilot bit solo, or we have an option of buying the TAB bit combo.
