Annular cutter

An annular cutter is a special drill bit that is used to make big holes in metal. It looks like a fat tube with a bunch of teeth on the bottom. When you put the annular cutter into a drilling machine and turn it on, the teeth on the bottom spin really fast and dig into the metal, making a clean and precise hole. It's like using a cookie cutter to make a big cookie out of a small piece of dough. Annular cutters are very strong and can make big holes without breaking or getting stuck. So, when you need to make a big hole in metal, you can use an annular cutter to do it quickly, easily, and neatly.
