## Customer Reviews

### ⭐⭐⭐⭐⭐ working as expected
*by Y***Y on March 13, 2024*

good quality, price should be lower for such a simple tool

### ⭐⭐⭐⭐⭐ Perfect drill press adapter
*by D***G on February 15, 2023*

I have no idea why this type of adapter is not more common, since annular cutters are so far superior to hole saws being used on drill presses. anyhow, the adapter fits 3/4 shank perfect and I had no issue fitting and using any of the annular cutters i have. It is a bit pricey, but worked very well for me. No complaints.

### ⭐⭐⭐⭐⭐ Perfect and well made.

As described! Delivered by horseback….
