Did I bring this drill to work with plexiglass? Build your own computer. I couldn't use it until the main electronics, motherboard and I/O, LEDs were done. So I didn't use the hole saw right away until yesterday. and found it slightly deformed. It doesn't cut a clean hole, ended up destroying 2 arc pieces that took me 2 hours to cut and glue, now it's runic. And it took a while to get the hole saw back. When you pay good money you expect a quality product, this is not it. Rather spend a few euros more and get quality.
