Does this price include the core bit shown?

It does NOT include the bit shown. You can get a 2.5" - 3" bit for $50 -$80 on Amazon... Hell of a drill and a great bargain. I have owned three SDT 85's prior to this because the STD 85's water feed is a major flaw. Had this one for month's and drilled hundreds of holes... still works perfect. Worth every penny.

I bought this with 3" and 4" core bits, but there is no pilot bit. Can you refer me to the appropriate pilot bit.

I have used this drill with up to a 4 1/2" bit. I do not use a pilot bit for drilling on flat surfaces. I drill mainly into masonry and concrete to anchor newel post for railing and fencing. This method would not be advisable for counter tops I think...We use a ply wood or composite lumber strip two or more inches wider than the hole and drill the appropriately sized hole with a hole-saw in it, centering the hole over my mark I use that to get the drill started. Once it is 3/16" or more into the material you can remove the guide if you want. It works well for us.

What's up with the water connection? I read it needs to be replaced or something. I would need to be able to hook up a garden hose to this

It connects to a standard garden hose, however every connection on mine was loose and had to be tightened in order to stop it from leaking

I am new with core drill. is there anything else i need to buy if i just need to drill a 4 inches hole? thanks!

You will need a 4" core drill bit if thats the hole size you need. It will screw onto your drill and you are ready to go except for water and power. Good luck.
