Review on 🚽 Enhance Your Bathroom Renovations with Drilax174 Diamond Granite Porcelain Cutting Tools, Hole Saws, and Accessories by Phillip Hoover

Purchased for drilling holes in ceramic drip irrigation pots. Tilt the chisel at a slight angle to get a reference point when starting. Then drill with medium and light pressure. Good work. No cracks! I don't know longevity. But one bit made three holes and was still good.
