These are great. I use them to drill holes in RC body shells. Has a nice clean hole.

### ⭐⭐⭐⭐ Initial impressions
*by R***M on January 19, 2026*

Haven't had a chance for thorough testing in multiple materials, but the edges on these bits seem like they'll probably do okay in wood and plastic... metal might be iffy. The included pouch, while a nice touch, came with inadequate hook & loop to hold the pouch flap closed and secure the bits. And what little hook & loop was there wasn't fully attached. Therefore one of my brand new bits fell onto the tile floor (not good for my bit or my tile).
