I use coconut oil as my cutting and tapping fluid/wax. It's a solid at room temperature, melts at skin temperature, has a high smoke point (450 deg F, if Wikipedia's to be believed), smells great, and is relatively cheap. And I don't know if it's the smell, but I never have to remind students to use it--they're all over it.
I picked up this tip from the shop manager at CU-Boulder and have never looked back.
