I think it will work great on sheetrock and fiberglass. I thought I was going to be drilling through fiberglass in my boat but turns out it was actually 3/16″ aluminum covered by carpet. The bits made it through for the two speaker holes I needed but most of the carbide grit was worn off and I trashed the bit. Looks like there are also teeth under the carbide so I may get more use out of it. It’s a quality heavy duty bit for what is intended for.
