Hougen Rotacut Hole Cutters - Trick-Tools.com

[@lunkydog]

I believe the "washer" on the small kit is also to keep you from plunging straight thru on the straight walled sizes 1/2" and above IIRC. The spring loaded center pin also acts as a ejector for the center plug.

Use a 1/16 pilot hole to locate the hole center and flip the material over to drill thicker material.

Do you have any " tips" on removing the cutter from the arbor after it gets tightened to the arbor?

[@YouTuber-mc2el]

You stated they cut 1/2" depth. The set that I have a 3/4" cutter will only get me 5/16". Bummer too because I'm cutting 3/8 material.

There are two different series from Hougen, the Holcutters are 1/4" depth and the Rotacut are 1/2" depth
