Review on Enhanced Concrete Core Adapter - Toolocity AD1112 by Alex Taylor

This adapter's threads don't go as far as the Toolocity 3/8" shank adapter, but it won't bend either. With another 1/4" gauge so I didn't have to use 2 5/8" shims to get in, I'd give it 5 stars. I only used it with a crown so it could work with other bits without washers just not mine.
