To cascade deletes, override the delete() method in your model:

class Model_Alpha extends ORM
{
  protected $_has_many = array(
    'beta' => array(
      'model' => 'beta',
      'foreign_key' => 'alpha_id',
    ),
    'gamma' => array(
      'model' => 'gamma',
      'foreign_key' => 'alpha_id',
    ),
  );

  function delete()
  {
    foreach($this->beta->find_all() as $entry)
      $entry->delete();
    foreach($this->gamma->find_all() as $entry)
      $entry->delete();
    parent::delete();
  }
}

You can then cascade further by overriding the delete() method on the models you're deleting.

I'm afraid there isn't in Kohana. If you really need one, you should apply it on the database level (ON DELETE CASCADE)
