Drilling on Masonry Block

I live in a townhouse and one side is a wall of masonry blocks. I've borrowed a hammer drill and masonry bit in the past when i was building a overhang storage loft.

This time around, I am just planning on installing one of those hooks to hold 40lbs and i don't want to borrow the tools again. I know I don't absolutely need a hammer drill (planning on using just a regular Rigid 18V drill and take my time) but do I need a masonry bit or can I get away with a typical titanium drill bit? the answer is that i probably need a masonry bit but was hoping someone has had luck with just a titanium drill bit.

Get a masonry bit. If you buy Tapcon screws, they often come with one. They're not expensive.

If you do buy a non-kit bit, buy a hammer (percussion) bit rather than just a rotary bit. Significantly better. I've had rotary bits disintegrate.

A titanium drill bit might work if you drill the mortar, but definitely not through the middle of a block. Personally, I wouldn't ever put a screw through mortar unless I had no choice. Holes through mortar are weak unless you use a lag that spans the entire joint.
