Would these burrs be approprate for use on copper based alloys such as brass and bronze?

I don't see why not. they are very aggressive, so you have to be very careful. I use them mostly on cast iron and aluminum.

Yes, you should have no problem using these with a standard drill bit chuck. These are a great value and last longer than I expected.

I had one of these a long time ago. As far as I can tell they are only intended for wood working not metal working. They are fine for a beginning wood turner doing pens, small bowls and the like. I have not done any work on metals, but I don't think I would start working metals on this lathe. However, I have heard of some people doing limited work on brass on similar lathes, but never stainless steel. But, as I said, I haven't done metal work so I might be mistaken.

somewhat...it depends on how much "Gunk" is in there....sometimes I clean the brass before decapping then clean the hole with a Q-tip.....

Not sure. But they are not brass and will not give you a false positive when cleaning for copper.

I drilled quite a few holes into some fairly thick aluminum pieces and had no problem. With some good metal specific drill bits you shouldn't have a problem.

I know of guys in the field who do use this on lead bends. They say you just have to be careful tightening the bolts. So, technically, "no," but field experience says "yes." I used one of these on a cast flange in a slab house...the old flange snapped right off at the floor. I marked the screw holes, drilled with carbide bit, and used plastic anchors and #12 stainless screws. It worked wonderfully and is a permanent fix.

I am far from an expert on this . I use them for jewelry making and cut thru stainless and silver plated silverware with no problem. Sorry I couldn't be more of a help.

Yes these bits will drill metal. However as with any drill bit a good cutting oil is necessary to keep the drill bit cool.

Yes they will. but if you run plated or FMJ, keep a tight eye on the expansion of the casing. If too small, you will get a projectile jammed into a too small casing. A fold of copper will develop as the bullet is pressing in. It really doesn't effect the discharge or the accuracy much but there might be some yuk factor to the buyer of the round.... A good gun will shoot almost anything but a squib.

That sounds like a really BAD idea. First of all, if your bores are so dirty that you felt inclined to put a power tool in them they must be really bad. Second, copper lead and brass are very soft metals, but I wouldn't put any other metals at high speed through my barrels.

I don't know why not. They are made of solid brass - same stuff plumbing fixtures are made of.

I don't believe it would and I am not going to ruin mine by trying. They are not designed for metal, especially that thick.

Not sure. I am a metalsmith (mostly silver) but have used it on copper components of the jewelry.

They will work... they are not sized as a wrench or nut driver... they are round but are aggressively made with sharp points to grab even if the hole is completely rounded. The problem here is these are QUITE SMALL and are made for removing very small screws. You can see by the image that they resemble "jewelers" screwdrivers 2-56, maybe up to 4-40, 6-32 is too large. Anything larger than 4-40 is probably not going to work. These work best on screws that are rounded off because someone was using a metric in lieu of a standard and vice-versa and the screw is not really imbedded with rust or threadlock for 30 years etc. Just want to emphasize, they are for tiny screws.

I believe they are asking the user to use these on sheet metal and flat banding. Do not use these as wire cutters. If you're cutting flat, not round material all should be well.

Have not tried it for your application. Hence, not sure. Should work it the copper is not finished.
