If the Core Catcher material is difficult to manually push out from the core catcher, use the Arbor Press (see Figure 4 and Figure 5). There are two different jigs is a jig that can be used to assist with the pushing . One for APC (Figure 6) either APC and one for XCB ((one for lower bit; Figure 76). Lubricate the moving parts of the arbor press with Lubriplate, or a mixture of Lubriplate and Marvel Mystery Oil.
There are two sides to the toothed, square rod that moves through the press. One has a longer end portion without teeth. Does your bit not fit? The end with the longer portion without teeth, must be on top. This sometimes gets flipped when opening the press for servicing. You should be able to retract the rod all the way into the press' gearbox.
See Figure 7 below.
