## Description

desertcart.com: PHITUODA 2 Inch / 50mm Diamond Drill Bits, Diamond Hole Saw Hollow Core Drill Bits for Glass Ceramic Porcelain Tiles Marble Granite Quartz : Tools & Home Improvement

Review: Works Well on Terracotta - This bit was a great value because it performed exactly as I had hoped. I used the bit to drill a hole to insert a spigot into a terracotta planter. The pot will be used with a rainchain to collect and divert roof runoff water. I used a regular handheld drill on fast speed at first to make an indentation into the pot and then I used slow speed to drill the hole. I poured water over the area about every 5 seconds to keep the pot from cracking. I found the bit easy to use because I didn't even have to press hard with the drill and I have small hands and am not partcularly strong. The hole (lol) process took less than five minutes and the bit seems barely worn. In the pictures, the worn bit is on the left. I used size 25mm for a 1 inch hole but had to enlarge the hole slightly because of the threads on the spigot; the 26mm bit would have worked better. I think I got my money's worth.
Review: Does the job - I brought this for a specific job, cutting hole for shower valve control and it worked great, just keep adding a little water and it's like butter on porcelain with minimal dust. It can be hard to start because it wants to jump around, what I did was use a dremmel diamond tip bit and scored the tile where I was gonna drill, then I started with this bit at 45 degrees and went slowly to perpendicular

### ⭐⭐⭐⭐ Worked well despite disposable build quality
*by T***9 on May 6, 2025*

Worked to cut through an inch thick ceramic planter without causing damage. I don't feel right giving it 5 stars because these are obviously cheaply produced and not meant for longevity, but beyond that they did the job for a good price.
