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.

What is the best drill bit for porcelain tile?

We recommend the DiamondSure wet drill bits for drilling through porcelain tile.

For drilling on granite, what bit do you recommend?

For drilling granite, we recommend using a diamond core bit .

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. To begin drilling into porcelain, start on an angle and begin the hole. Once you have started the hole, adjust the drill bit so it goes straight and creates a flush hole. You can use a template to cut holes in specific areas.

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.

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.

Does this come with all the bits or do you just pay for one?

These porcelain bits are all sold individually.

They get the job done

I love my drill bits and they arrived in good order however I was dissatisfied with the high shipping charge. I used the same envelope to mail something of mine and the postage was under five dollars dollars but I paid $13.95 for 2 bits weighing the same as what I put in the mail

Awful Useless Product

This was an absolutely useless product. We couldn’t drill a single 1/4” hole through a porcelain floor tile. Unfortunately I purchased multiple bits and hole saws. One of my tradesmen has his own Bosch kit. The Bosch bits worked fine.

EXCELLENT PRODUCT !!

Excellent product. I only wish these hole saws were made in larger diameters.

No worries with these drills!

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)

cuts good

Cut through subway tile pretty quick for a diamond hole bit. keepin it wet of course
