You need to move with the times and go to sds. I can't say I've seen
large diameter plain-shanked masonry bits for years.

There are multi-material bits (I use in my combi drill), but only up
to about 12mm

I wouldn't be surprised if a Chinese 1 metre 25 mm SDS bit and a basic drill
for maybe £50 was cheaper than a "western" plain drill on its own
