It showed up on time and worked perfectly. I used a little running water while I drilled and it went a lot smoother than just using it by itself.
This bit worked well with concrete!!
It is easy to drill for the first time. I worked on the tiles in our bathroom and I like how easy it is to enlarge a hole and get a precise one.
Got this to finish up a new install of a soap dispenser. Got a porcelain sink and was able to cut a hole, and I'll skip the details on that job. I use this bit with a drill driver to work the sharp edges off as a final finish. The diamond grits are very hard and work well to dust away the sharp ends and turn them into good chamfered rims. Worked well with distilled water and got the job done within just minutes.
The Chamfer Bit is a great finishing tool for holes in rock, concrete, and brick. It is a well-made tool that provides a nice smooth edge to the facing of rock, concrete, and brick for ease of pass-through applications and to prevent cracking and braking of facing material. It makes the difference between a hack job and a professional installation.
