### ⭐⭐⭐⭐ Caution, Page is not clear.
*by H***E on August 4, 2022*

First off, you are ordering one (1) of the items pictured on this page. And they are not shown in order.Second, these are listed by Pilot size, not Bore diameter & depth of cut.Wasn't what was needed for this project, but I'm sure we'll find a use for it someday. It is a good quality, just the wrong size today.

### ⭐⭐⭐ Misleading add
*by W***M on October 13, 2021*

Misleading add. The pictures show 5 bits, but the description states 1 bit.
