[QUOTE="Mike678, post: 616174, member: 16778"] I have brazed a good number of carbide tips to teeth for a drilling rig .I used to operate it for opal mining . Also silver soldered a number for lathe tools . MY tips are to grind the carbide with a green wheel if possible , to remove any coating . Drop into metho or petrol to clean well . Heat up carefully , do not over heat or you will put oxide on the surface . [/QUOTE]
