I did not use the anchors but according to the instructions an 8mm bit is needed. If wood stud wall mounting the anchors are not needed and a 3mm bit is used to pre-drill.

The bolt (screw) circle is 11 5/8" so the hole diameter should be about 1/2" smaller than that or NO BIGGER THAN 11 1/8" otherwise the screws will have nothing to screw into. You can probably get away with using only 4 screws at 12-3-6 and 9 O'Clock. That's what I did.

Use the hammer drill. Start with a bit one size smaller than what you need.

It has to be the same chuck size. Check the drill and the bit before purchase.

Maximum screw placement is 17". If your studs are 18" OC, you can make it work. Pre-drill pilot holes at outward angle of about 20 degrees. If your space is 18" inside the studs, you'll need to use an anchor on one side. My preference is the Hilti Toggler Bolt. Use a lag screw in one stud and space the other anchor as far apart as possible. This minimizes the distance to the stud. Then install an extra drywall screw in the stud as close as possible to the anchor. The smaller the drywall area between those two points, the stronger it will be. I'd even add a second anchor on that side, 2" closer to the center. If your equipment is heavy though, you might want to purchase something different. Maximum screw placement is 17".

I used a 1/2 inch diamond drill bit (it's not like a normal bit, it's hollow in the middle), you can purchase at your local home improvement store. There are videos that will show you the procedure. I just saw the other comments, those are wrong. I just checked my drill bit to make sure, it is 1/2 inch. DON'T use anything bigger or you will have a giant hole in your nice counter tops.

I think the instruxction calls for a 5/8 inch bit, I would use a metal drill bit if I were you.

That depends on the size of the wood screw you are using. I believe I used 1/4" diam screws so drill was about 3/16"

At the hardware store, get a closed circle hook with the appropriate weight limit. The package usually tells what size hole to drill for it. If it doesn't, you can hold a drill bit in front of the "screw" part of the hook. If you can see the entire threads of the screw on both sides of the drill bit at the same time, it's the right size.

You will need a masonry drill bit, a concrete/masonry anchor (insert) and a screw to match. Any hardware / home improvement store can help you figure out what you need.

Use a 1.25" spade bit to drill a 1.25" hole. The package include a template for locating the hole and mounting screws. I installed it on a steel door using the template. Worked fine.

Go down to your local hardware store and tell them what you are trying to do - they will point you towards the right hardware. Briefly, you're going to want a HSS (high speed steel) or a titanium carbon-coated drill bit and the right screws. Make sure you're not exceeding weight specs (for the mount OR your wall)

The hole needs to be big enough for the bolt and wirers. One inch is big enough for most wirers. Now with the bolt though the hole shift the base over to see the hole place the wirers though then shift it back and tighten the bolt.

It comes with a Philip and Flat Tip combination drill bit. You can use that as a sample to get the right size you want.

We bought them for my dad. He said he used either a 1/8 or 3/16 drill bit. He said it stated in the directions which size to use. If you got yours second hand and it didn't have the directions he said you need to drill a hole to accommodate the size of screws you are using.
