Electrical discharge machining assembly including electrode

An electrical discharge machining (EDM) electrode, comprising:

• an electrode first end;
• an electrode second end opposed to the electrode first end;
• an electrode longitudinal axis that extends between the electrode first end and the electrode second end;
• an electrode axial opening that extends between, and opens at, the electrode first end and the electrode second end;
• an electrode first portion that includes the electrode first end;
• and
• an electrode second portion that includes the electrode second end, wherein
• the electrode is electrically conductive,
• the electrode first portion has a first flexibility,
• the electrode first portion includes
• an axially-extending fluid path corresponding to the axial opening that allows fluid communication between the axial opening and an exterior of the electrode, and
• a second fluid path that allows fluid communication between the axial opening and an exterior of the electrode, the second fluid path extending radially with respect to the longitudinal axis,
• the electrode second portion has a second flexibility, and
• the second flexibility is less than the first flexibility.
