Drill bit?
#1

So recently bought a Tapcon hammer drill bit with carbide tip for concrete, the guy and homedepot said it would work for what I’m doing, I’m trying to install a latch on the corner of my house between the garage an house but it’s rock not concrete, brick or block, I got about 1/2 inch in each hole before the bit was smoked, not exactly the best hammer drill that I'm using either, what exactly am I doing wrong or what type of bit do I need to use? Thanks

They are just like using a regular bit trying to drill steel, it's an extremely hard material and those are not the best bits.
I have dozens of them, sometimes it takes a couple but they sharpen easy!

Bits used for concrete, masonry, brick, and block need to be carbide tipped or they will dull instantly. They also cannot be sharpened.
A drill with a hammer function (hammer drill) will work better for drilling into rock when using carbide tipped bits. I am a fan of SDS hammer drills but a "screamer" hammer drill with a standard chuck will also work.

You cannot use tapcons in rock. It's too hard for them.
You also need to use a diamond bit when drilling rock.
You may need to use lead shields in the rock to screw into.

Lead shields come in all sizes. You may want to use 1/4" - 5/16" - 3/8" galv. lag bolts.
The link below is for 3/8"s but they have all the sizes.
