This head features a 5" protractor, radial index cheater, micro height adjustment, positive stop moveable pointer, and a dop arm with interchangeable coletts, 1/4 to 5/16" size.  The entire dop arm assembly can be removed from the facet head yoke.  This is accomplished by unlocking the point on the operator side and pulling out.  Points are 3/8" 60 degree steel.  Point inserts are brass. The dop arm assembly is also counter-balanced so that the dop arm will rise up when the operator lets go.
