Do these cut in such a way that it forms a long plug or does it "wear a hole" like a carbide bit? What coolant is recommended, water or oil?

Wears a hole in wine bottles... works well with water as a lube. I have a spritzer bottle that I spray with.

It removes a plug. If you don't clean it and allow the plug to stay in the "drill" it will soon stop working. Keep it open. I have never used oil with mine. I drill fused glass pieces and have always drilled under water. I hope this helps youdave

I used a handheld drill and it took about 45 minutes to drill through a 3/8"thick glass vase bottom, with soapy water as lubricant. The drill is hollow, so it did produce a glass plug.

Yes, but as with all diamond cutting tools you need to keep them cool. Slow speed and constant coolant flow will make them work better and last longer. Cold water can be used for the coolant. (Squirt bottle works great).

I disagree on the high-temperature comment. I use this for valve cover gaskets on a large (1200cc) air cooled motorcycle engine. The material is thick enough and soft enough that it pretty well stops oil seep, even though I'm using full synthetic light weight oil. Unlike some other materials (cork, for instance), I don't worry about bits breaking off and getting into the engine.The wrapper that comes with it says it's for sealing oil, water, or gasoline.I especially like it because with aluminum, there's a lot less torque for clamping down, and the soft thick material compensates for irregularities pretty well.

I used them dry, because they are supposed to hold up, however i burned through the bit pretty quick. I highly suggest a cutting oil when using these, especially on steel.

Cutting tough Aircraft material are depend on the type of cutter or carbite tool bits etc. All I know this Proxxon are good motor, strong torque, stable speed, not likely jamb, stop or stuck while cutting. excessive hogging may cause it too hot and burn out the switch (Repaired under warranty and still works great for years now)

It works that way for me. No leaks. For best results lube the plug. I used a very light coat of silicon grease, which I rubbed in and wiped off extra. Seals and opens easily now.

If a tire has a an inch long cut I would say it is rendered perilous and should not be used. However, in a pinch, you could put multiple plugs in the cut and it will seal and work. I picked up a razor in my tire once, I put, if I remember correctly, three plugs in the slit and it has not leaked for months. I will not be surprised if it starts to leak again, but it is fixed for now, so I don't care. Yes, it will probably work, no it is not advisable. I would do it to my own tire but not to someone else's.

I have had two (2) of these Mc Elect Chain Saws. Never lubed the tip, just topped up the lube tank, plugged 'er in and let it rip.

I've been using it to drill through shovel heads and its worked great. Does not have a liquid/coolant attachment. If its just an occasional job it will probably just fine. If you going to do a lot of metal cutting better off getting a drill press thats has the coolant attachment.

The aluminum bits will not hurt plastic. My Saturn had a plastic tank too. Think of it as more like glitter. When heated and running through a small leak it gets caught and eventually blocks the leak. My car took two applications for a minor leak, but it has been good since (about 6 months). Hope this helps.

I have used these bits both ways. Ideally I like to use cutting oil but sometimes if I am in a bind I will use them dry. The best bits I have ever owned.

Yes without question cutting fluid helps keep bit cool and from overheating causing premature bit dulling

I have been using Liquid Wrench, available at most hardware stores, and maybe here on Amazon too though I haven't checked. It is similar to 3-N-1, a common household light oil which I believe will work just as well. All you want is lubrication. Nothing to heavy, just a light oil to help clear the hair and let the blades slide across each other easily. I believe either oil will work just as well.

I use standard generic chain saw oil with no problem and I have never drained it out. I have never had any oil dripping as a result. Love my Makita!

Typically water is used as a coolant/lubricant for home use with these kind of bits. It's trickled over the area you're working on to keep the friction of the bit against the surface from heating things up and doing damage, like shattering in the case of glass, or ruing the bit in the case of metal. Just be careful not to get it in your rotary tool!

Wont hurt anything I was driving for a year with it leaking water into the oil seems the oil is so hot it steams the water out of the oil. I wouldnt go out of my way to put extra coolant in the oil and why dont you drain the coolant first. Its at the top of the engine prb drained down lower. I saw no coolant in mine and like you say change the oil. I just traded my 2001 Impala 118K mi for a 2013 Altima I am tired of fixing stuff. Everything was about to go in that car. Tranny was next.

Yes anti seize lubricant is good. It acts like a shield around the threads against carbon built up. Very much easier to remove the plugs later.
