Review on 🖤 【Black】6 Piece Ceramic Mgtgbao Concrete Tungsten Set by Cory Mosley

I used these drill bits to drill drainage holes in small glass objects that can be used as tiny outdoor plant pots. If you follow what one person said by using a small jet of water to lubricate and cool the drilling process, they work great. Don't try to drill too hard into the glass as you could break the glass. Also use them on small ceramic pots for succulents. Just take your time and let the drill do its job and it will make a perfect hole. Always wear safety goggles when drilling anything that can break.
