Do Masonary drill bits require a hammer drill in order to use them?

Depends what you are trying to drill through, but a hammer drill isn't required.
Drilling through concrete the aggregate will make it tough without the hammer drill, but a chisel can be used to break them up.

My thoughts as well.

You will burn up a masonry bit very quickly if it isn't in "hammer" mode, in my experience.

As with so many other things it varies. You can do without on softer materials, and using slow speeds on harder materials. Also smaller holes may be do-able without a HD. All the HD's I've seen have an option to switch the 'hammer' off, and if you're not using it a lot a cheaper HD is well worth considering since it does double-duty. On harder materials it might take as much as ten times longer without a HD, and some things will be darn-near impossible without it. Larger ones can be rented and may come with bits so for a one-time use that may be an option to consider too.

Just saying: I bought a BOSCH masonry bit a few years back...After many uses, it is still as sharp as new.

And where did I buy it? Not in the USA, but on a vacation trip abroad.

So this is what general contractors are doing on their vacations.

When traveling or in a new town, I always keep a sharp lookout for old hardware stores. Sometimes they haven't updated the prices since they stocked an item back in 1982 :cool: Yeah, Bosch masonry bits are good ones.

I was given a box of generic Tapcon screws and my bits seemed oversized for them so I ground one a little narrower with the diamond blade in my mini-grinder- then they worked like a charm!
