I want to create some core drills for a project with various grades of diamond powder and was wondering what you would recommend for attaching it to the end of the drill bit.
I've looked at diamond brazing rods but they are as rare as rocking horse shit.
Also thought of casting some tough RTV silicone caps with the powder in. I may have a bash at that some day.
So the idea is to to mix in the powered diamonds to a something, then dipping the end of the tube in it and hopefully it will set hard enough not to crack off the pipe whilst machining.
