Can you set a corner finisher / flusher head to leave on less material?

TapeTech has two different tool categories for finishing internal corners.  Corner Flushers and Corner Finishers

If you have what TapeTech refers to as a corner flusher, there is no way to adjust the amount of joint compound the tool leaves in the corner.

However, our Adjustable Corner Finishers, models 48TT and 48XTT, have adjustment arms on the back of the tool that allow you to increase or decrease the amount of pressure, thereby allowing you to leave more or less compound on one side, or both sides, of an internal corner. Models 40TT, 42TT and 45TT Corner Finishers do not have adjustment arms.
