Jet Sub

- These over-the-hammer jet subs will allow large volumes of air to be bypassed above the hammer.
- This reduces operating pressure and allows better hole cleaning for deep, wet, or soft rock applications.
- The top ring must be drilled out per the flow chart (see below).
- Additional rings are available to drill out for different flow characteristics.
- Must be run pin up.
