I bought a dremel recently and it comes with a so called"Diamond particles" coated cutting bit.?
My question is this : Are the diamond particles made out of real diamonds ?? If they are real diamonds , how can they be so cheap ?? Isnt diamond expensive ?
Yes, it really is tipped with diamond dust. Industrial-grade diamond is really quite inexpensive, unlike the stones you'd buy in a jewelry store. Your diamond tip is made for cutting very hard materials, but is easily damaged by trying to force it to cut too fast.
