This is a replacement draw bar for the Optimum BF-20L mill. This mill, at least in Australia, comes from the factory with a draw bar that has a 1/2 Whitworth thread. Unfortunately this precludes the user from using commonly available M12 tooling.
The material is a high performance tool steel and it is precision CNC machined. This drawbar will fit any BF-20 mill. I can send international or within Australia.
