Coated burrs worth it?

[BOOT]

Gonna order some new burrs for CI & alum soon and wonder if I should spring for the titanium coating this time. Any notice an improve life or less chip loading on alum?

[cgarb]

There are several different coatings. TIN coating is probably the most widespread. It must be cheap to do also because they coat everything with it. I know for a fact it will make a carbide insert not as sharp, the coating must slightly round the cutting edge. Sometimes a really hard material, or something with a thin wall thickness that is chatter prone a coated insert won't cut as well as a bare carbide edge will. I would think that it would perform better on iron than aluminum. Iron is a very abrasive metal and anything to help keep an edge protected will probably help burr life.

I do not use them. I have but still prefer non coated. For aluminum, I like to use lps tapmatic edge tapping/cutting lube it's a 14oz tube. Get the burr warm insert into the wax-like lube and cut. It really improves the life of your burrs.

The nice thing is it clings so well to the chips, that they don't fly around. But then again that's the negative.

When cutting alum. To stop a carbide burr jamming up with alum chips, wipe the burr over a bar of soap.

I use Irish Spring... Manly but my wife likes it, too!

Candle works too.

i use a waxy aluminum cutting lube called boelube used in the aircraft industry. if you try it you wont use anything else

Where do you get the stuff? I just googled it and didn't even find it.

That's exactly what I do, I use regular dial soap, I prefer dry soap vs wet n messy alternatives. Just figured maybe with the coating I may have to stop n cool the burr less but seems from the answers it'd be worse. Stupid alum and low melt temp sticking to hot burrs. I haven't messed with alum much n I'm sure there is a method to load up less, I prob should cut slower or something.

i just googled it and there were numerous listings

I've been researching this lately for another application.
For aluminum bare carbide is probably best, and the smoother and sharper the better.
Lots of different lubes to try. I like how alcohol leaves no residue.

I have never noticed it being worth it to me, jmo
