A: Grainger sells a kit of 3 of these bits. Theirs say porcelain. So I imagine if you go slow and easy you should be ok.

A: WingIt's sell their own grab bars. If the gauge of the WingIt's bolt is comparable to 3/16" or 1/4", (t's probably a #10), then you're fine with any Grab Bar. What you're really asking is what is the diameter on the mounting hole on a Grab Bar and what is the gauge of the bolt or screw. If in doubt, then buy some everbilt toggle bolts, they have Truss Heads that are great when the GB hole turns out to be larger than expected. As soon as you buy your GB's, all will be revealed.
A: I bought a Glacier Bay (20135-03202-36) which specified Wing-It compatible on the box. The Store SKU (240826) is the easiest # to search on HD app/website - then just choose desired length.
A: I don’t remember the brand of grab bar I used but it was nothing specific for WingIt anchors. I used a grab bar based on the length I needed. I installed the grab bar on tile and it was as secure as if I screwed into studs. Fantastic anchor, I will definitely use again.
A: Yes. From the HD Wingits Apache product page: "...as you drill through ceramic wall tile, masonry board, marble, steel, glass and plaster,..."
A: I'd give you a very firm "probably", as they are designed to go through ceramic/porcelain tiles. However, you can buy a set of assorted sized carbide glass and tile bits for less than the cost of this bit.
A: tried it on ceramic tile .could not even get one hole done and it broke the bit and cracked the tile
