This is a boring bar I designed and machined. Key features include the replaceable carbide insert and cooling/air hole down the middle to clear chips.

Project Detail
This project consisted of designing and machining a deep, replaceable insert, chip-clearing boring bar. After pricing similar items, it seemed best to machine one. It was designed to fit the quick-change boring bar holder and accommodate carbide inserts I already use with other tooling. Also, to clear chips, the whole assembly was drilled out for compressed air to blow down the center. To aid in alignment the shaft was knurled at the large diameter that supports it against the tool-holder.
