What is the best bit for putting a 3" dia. hole thru the stucco exterior wall of my home?
Will the 6755 work?
This drill bit is not recommended for drilling through stucco. It is designed for porcelain tile.
Why am I unable to add items to my cart????

Does this come with all the bits or do you just pay for one?
These porcelain bits are all sold individually.
I need to cut glass discs from 1/16" thick borosilicate plate glass. Can these cutters do the job, without significant chipping of the outside edge of the disk, and without excessive wear?
These diamond drill bits are designed for ceramic, porcelain and glass tile. 1/16" material is very thin and may crack entirely due to the stress of cutting. If you are able to get a successful cut, you will still need to knock the disc out of the hole saw, which may likely result in chipping the edge or fracturing the disc.
Good luck !
Let us know if you have any other questions.
For the larger diameters do you need to purchase a pilot bit?
At the larger sizes you can use a pilot bit to start the hole, but it is not needed to be used with these bits.
if there is no pilot bit in the center of the hole saw. how do you cut a hole in a specific place? like a drain.
Pilots in diamond drill bits have become less common due to them wearing before the bit does, the extended length of time cutting hard materials, and do not allow use of center water-feed equipment. You can use a template to cut holes in specific areas.

The only bit that worked for us drilling hard porcelain tile.Up to 24 holes and the bit is still going strong(1/4 inch). Just follow the directions as described. We tried many others and got nowhere.
Excellent, Highly recommend.

Best tool to do the job. Works everytime used.
Cut through glass subway tile with ease

Using the spear shaped bits available at the big box stores are a waste of time and money. Unfortunately I wasted many hours, numerous pieces of tile, and bought several useless bits before I learned that lesson. I'll never attempt glass drilling again without these diamond bits.
best bit for the money

I just had two bathrooms professionally completed and decided to install a grab bar in the shower after they had left. The contractors had remarked about their difficulty in securing cabinets to the walls since the tile was unbeliveably hard so I was apprehensive about cutting 1 1'/4" holes into it. As a first time use of any bits for tile, this one was a breeze to use and not one chip on the finished holes!

These drills are the real deal. If you keep them lubricated you will have long life. I used them to drill holes in PE5 porcelain tile for my walk in shower door frame and they worked as good on the last hole as they did on the first. (Tip - clean the ID hole between each hole)
