Purposes are rabbets and sometimes tenons.

Reasons are safety and precision.

Safety, because the blades stay buried under the wood being cut and the sacrificial fence. However, I still don’t use my hands to move the wood or hold it down; I gots enough push pads and blocks and other accessories that I don’t need my naked hands near even a covered blade.

Precision, because it lets you “fit” the rabbet. I often use rabbets on plywood edges for cabinets. Plywood ain’t NEVER 3/4”. So I set up a 3/4” dado and bury a 1/16 under the sacrificial fence. Make a test rabbet and try to fit another piece of plywood in it. The new piece will be proud (usually about 1/32”). I scooch the fence over a little less than that and recut the test rabbet. Try the fit again. Usually just barely proud. Scooch and test again, until I’ve “snuck up” on a perfectly flush fit.

Always fit, sneaking up on the exact right size. Never measure.
