When to choose it

The 1901 makes an edge recess with a listed 3/8-inch radial depth and a half-inch axial cutting section. It fits a back-panel or overlapping joint design when those are the two dimensions you need.

Compare it with the thinner 1914 slotting profile if the axial cut should be only 1/4 inch. Both list a 3/8-inch radial depth with their stated bearing arrangement.
