I am using my dremel tips to drill holes in plastic. I am using these tips http://www.micromark.com/20-PIECE-DIAMOND-COATED-MICRO-BURR-SET-1and8-SHANK,7593.html and others from micromark in larger sets. When I do it though, it melts the plastic a bit and gets stuck in on the bit and I dont know how to get it off, can anyone help?
You could soak them in lacquer thinner, MEK or Tenax to disolve the plastic off them.
I don’t know if it would affect the burrs or not but I wouldn’t think so.
Maybe you could sent Micro-Mark and email and ask them.
Too much speed, too much pressure…you getting heat buildup causing the plastic to melt and stick. If you get a plastic cooccon around the tip you can score with a knife and split it. Soaking as described above works too…in MEK.
This works great! It’s a soft stone-like manufactured material that abrades the stuff clogging the bit, but doesn’t damage the bit.

It doesnt serem to be cutting if I dont add the pressure and or speed…
My thought is, why use a diamond burr for plastic?
There were designed to cut hard materials. Get a steel bit and slow the Dremel down to get the desired results.
Mainly because a single steel bit could be 10-15$ but the whole set of diamond ones I bought were 13
Diamond burrs are abrasive in action; metal or carbide bits cut. Different functions and uses.
These are $8 for a set of four:

With a different collar size in your Dremel you could use standard drill bits as well and the collar will not cost you but a couple of dollars.
maybe, but I’d rather just clean the diamond ones, I have so many different ones that were so inexpensive, I havent needed a shape that I didnt have
Watch out for those Bargain priced diamond bits…soaking can and sometimes will cause them to dissolve. You’ll find out this has happened when you turn on the tool and get a face full of scrapnel. WEAR SAFETY GLASSES!
I trust micromark not to put out crappy products like that, eveything I have purchased from them has been top notch, and if I do get shrapeneled, they will get laywered
It’s still a good idea to ALWAYS wear safety glasses when using a Dremel.
You only have one set of eyes. [:)]
