Using it in a wet-only environment helps manage heat and dust, contributing to a cleaner, safer workspace. The wet-drilling capability also extends the life of the bit, reducing wear compared to dry drilling. It's ideal for longer jobs where precision and extended use are key.

### ⭐⭐⭐⭐⭐ Good bit. Preforms well
*by R***N on August 16, 2025*

Great bit. Went through a lot of rebar and it held up well. I rent the drill stand and I’m always worried about hurting a rental bit. This is great didn’t have to worry and saved the bit rental. Will be buying all the sizes I commonly use.
