Shaper cutting extra long chips - GIF

Well, this is a Planer, not a Shaper. I bet he can make money with that machine!

Having run both, they'll cut profiles difficult to generate with a rotating cutter, or into recesses that aren't accessible otherwise.
Not ultra surprised of the chip length, a nicely ground and honed HSS toolbit. in what appears aluminum. BTW, that tool looks at least partially hand-ground. It's very rare that a single point carbide would be used, not appreciative being dragged on return stroke.

The planer is still king when it comes to work such as press brake dies, long molds (ie door seal on your garage). The general use of shapers and planers is per video, using single point cutters figuratively same as lathes, including form tools. They use a clapper box, like shapers; however being offset from the supporting mount, lack the rigidity of a direct ram.

Many planers also mount self powered milling spindles, anything R8 and up. Planers are hydraulically driven tables, easily throttling down for appropriate feed rates to accommodate rotating cutters.
