I used them to grind holes in quartz crystals. they grind,not drill. It's slow but they work.John

Yes, just hold the stone steady so you don't wallow out the hole. blow the dust away periodically or keep the stone wet.

I would say yes. Agate falls into the same Mohs hardness scale as glass (6-7) and that's what I use them for. Just makes sure to drill using water and take your time (lots of YouTube videos). Lasco makes great quality bits.

No; I use them in a Makita Drill (Any Electric Drill will work). Have saved a ton of money and time by sharpening my own Chain Saw Blades.

Any drill will work however a variable speed is better and should use water to keep them from overheating

As far as wood is concerned absolutely. I have not needed to drill any metal with these particular drills, however I would have to say that as long as you used them properly ( using lubricant and not trying to go too fast ) I would thing these would work well on most metals.

I just took a magnet to them. They are magnetic. We have a 1/2" drill, but yes they would fit in a 3/8" drill too.

Yes they wil.l I would recommend using a lubricant while drilling and a low speed setting.The small taps will break if you force slot of pressure.

You should be able to use them just fine with any good drill, especially cordless ones.

I have not tried these in my cordless drill, but they should work fairly well. I have used smaller shanked drill bits, so these should work. These are made for Dremel type hand tools that turn quite a lot faster. Give it a try................

No, or at least I did not. You will be able to use them in any drill or drill press. My only problem is that it was difficult to tighten the chuck enough to prevent them from spinning when the going got difficult. A hex end more like regular bits would prevent that. But, the bottom line is I have always gotten the job done with them.

Yes, just run water on the bit while you cut. I used them on granite slabs and they worked great.

yes sure they will. You will need to do some drilling more than likely. I had to do 4 holes on each side. its not to hard just mark spot and drill. they are strong, good looking to . a good buy

Absolutely, at least I have used them. I believe this hammer drill with a psck of upgraded bits, is the best tool purchase I have made in years!

They will cut stainless but you have to go slow and use cutting oil or they will burn out rather quickly. I have only used them on thin stainless to re-size a previously drilled hole. Good luck!

These will work in drills with three-jawed chucks that will take 1/4" size drill bits.Hope this helps.

I haven't done it but I have seen them with holes. Be sure to use the proper bit and I think you will need to follow the guidelines of drilling glass...keep glass and bit cool.

I would think so. I have a Black & Decker bit set and the drill has had no issues with using them.

Pretty sure. I'm using them in a DeWalt electric drill. I think they're universal but not for certain.
