Would these drill through thick seashells without getting hot and breaking?

I wouldn't think that they would drill in to seashell. They are not very sharp. They are excellent with a hammer drill on concrete. I would use a glass bit for the shells

They might, but some will not, I had two that got stuck in my Bosh hammer drill, I almost damaged the drill getting them out. If I recall these bits are $19.99 or may be $29.99. So take your chances.

I wouldn't put them on an impact if that's what you're asking. I'm sure they'd shatter. I'm a body man and have used them on 1/3 and 3/8 lithium ion drives from Milwaukee with no problems.

These drill bits should have no problem drilling into metal, however, the smaller sized bits are more likely to break if to much pressure is applied. That said, these bits are of the highest quality and are less likely to break than others on the market. You get what you pay for.

Yes. Yes might be an overkill though. These are extremely durable bits and do well in any kind of steel I have ever drilled so plastic should not be a problem.

I think so, they are pretty thick! Just rip each one out and it should be fine.

I have never tried to drill through those types of matterial. I only use it on plastic parts for model kits. If you take your time it might still work, but I feel a dremel would probably work better to get through shells.

For seashells your best using a blade rated to handle cutting ceramics. If this blade is rated for ceramics, then you should be fine. If not, then I would not risk the harm to you, the tool, or your shells.

Yes, be really careful. Start slowly, Especially if you are drilling something delicate.

It depends on the size of the hole. They are pretty flexible, so its possible.

I have not tried them on anything, but they appear to be good tools and well made. I would not hesitate to try them, especially on Aluminum. Copper, if it is very thick > 1/8" may need greater care, as copper and brass tend to grab. Often specially ground drills are used to cut more slowly, but I would not be afraid to try them, especially in a drill press where greater control than a hand held drill is possible.

I use them in my 1/4" dewalt impact drill from time to time , especially in tight spots like small 9" or 12" cabinets. No problems so far.

If you have a good battery operated drill, the answer is it depends. If the sand is soft and will cave into the hole, it is up to you. If you around tree roots the answer is no. Remember this drill bit is not from harden steel and it will bend. Also, the drill may spin in a the Chuck of the drill.

Wow, that is a hard question to answer (get it?). What i have found is that they will drill very well so long as there is ample amounts of water to cool the bits. We have used them to cut holes through over 20 wine bottles and they still cut. We use lots of water to lubricate and cool the bits as well as to flush away the sludge. Heck if it takes a bit per two holes you're still doing well. These are not expensive bits to begin with. But they do cut through glass well.

With a little care they can be used in hand held drill. I would make sure the piece is securely clamped.

No. They're pretty strong. It would probably take plyers and a hammer to bend them.

I do not think these will be thick enough. I use them for melting lead and they are marginally thick for handling the metal dipper. Had to wrap the steel dipper handle to keep the heat from being too much. Only have lead at 700 degrees.
