Tapered Deep Hollowing System
The Tapered Deep Hollowing System was designed by Mark St.Leger and is manufactured by Mike Hunter. The components to this new system are two boring bar choices and a three-tool cutter package.
Four grub screws are drilled with the thought that if two got messed up there are two more to take their place. It is actually a good practice to tighten all four grub screws there is a lot of torque at the tool tip at 17” of depth (someone aggressive might just spin the tool with only two tightened).
