I’m assuming you’re using a masonry bit so I’m gonna give you another tip:
LET THE BIT/DRILL COOL DOWN. You might burn the drill out and you WILL dull the bit. You don’t need to drill through in one shot…drill for 20-30 seconds and wait a few minutes. It’s slow but worth it.
Masonry bits are carbide tipped and don’t dull, they just break. Heat is not an issue and the bit doesn’t even function by cutting. It’s a downward 45 angle in order to chip as it rotates. There’s no cutting force from the rotation.
You’ll be ok.

Good masonry bits are carbide-tipped but not all of them. I used those with our sls drill but I stuck to the cheaper ones for anything under 1/2"
Perhaps dull was the wrong word but the tips do wear out. You wind up with a useless flat stub at the end that won’t push through anything
