*by W***R on December 11, 2025*

This drill bit work and did what I wanted it to do. Easy to use and I will need to order some smaller ones for a future project.

### ⭐⭐⭐⭐⭐ Amazing value, durable, and clean edges!
*by M***O on June 30, 2020*

There is a little bit of a learning curve based on the wood that you are using. I had never used these type of bits before, but I quickly realized that in order to effectively drill mortise/tenon joints without having to spend a ton of time chiselling, I could just measure and drill small pilot holes spaced just inside the span of each bit. Huuuge time saver! They are sharp and ready to work. Well oiled for storage (for the couple of sizes I haven't used and likely won't often). Amazing value for the set compared to others selling singles!!
