What good drill bit can I use to drill into stone (rock wall)?
Question:
Answers:
Carbide tipped masonry bit. Make sure that it's for rock and not just for brick. Brick bits will be cheaper but they may not do the job. If you just have one hole to drill perhaps you can go the cheap route and sacrifice the cheap bit. If the job is more extensive, don't skimp. Get a good grade bit. Might be possible to rent a hammerdrill with bit at a home improvement store. Again, if the job is too heavy you could end up sacrificing the bit and your own drill so get guidance and dont try to save pennies.
Masonry bits/Tap Con bits, certainly have more than one on hand. You don't detail the size hole you want. The large the hole the more power your drill should have, and likely you should run smaller bits initially (pilot hole) working your way up.
The masonry/tap con bits will have a kind of "plow" at their tip.
S.W.
Carbide tipped masonry bits are okay. Stone varies a lot in hardness. The bits called "percussion bits" tend to be tougher because they are made for use with hammer/drills. Either way, you should get carbide tipped.

You need the right tool for the job. Masonry bits are sold at your local Home Depot as well as a good hammer drill. You will need both to do it properly
