The wax core very soon disintegrates in use. What is it for and are you supposed to add more wax?
Hello Speckledhen,
The wax core is a coolant system and absorbs heat during drilling. Once cool, the wax will reset, ready to cool and lubricate the drill bit again. There should be no need to add more wax.
Thank you for using Q and A
