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

Re: drill bits

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.

Re: drill bits

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!
