It does fine . Problem is I haven't got enough run time on it in 5-6 -7 years to even seat the rings yet . Maybe an hour 2 at the most run time .
That's one problem with a big azzed saw like that is finding enough big stuff to put it under load . 20 inch stuff is childs play for that thing . These things run an 8 tooth .404 as standard equipment because of the torque they produce .
With iron bore and tool steel rings it might be a long time until get set in .It does okay though because the rings seat some under pressure .Better of course if fully seated .
