These are great for wood. If you are using them for metal you may want to swap out the drill bit

Came with extra bits which is nice. Springs are not so smooth. These types of bits tend to work better with a beveled tip. These are flat so it's necessary for shroud to fit precisely into your tap hole, not so versatile that way. They're ok. Maybe update once I've used them some more.
