Review on 🔩 Hardened Plastic Drywall Drilling Mandrels by Sfl Richardson

Honestly. Don't skimp on tools. I only needed two sizes, so I figured this whole set at Home Depot was cheaper than one size. And I understood why. The first had trouble cutting through 1/2 inch plywood. The set screw holding the bit was removed so it could not be realigned. I ended up throwing them away and buying a real bat. Don't waste money and time. Get quality once or buy twice.
