Here is a drilling tip from @kkmetalwerk4640 - “While making a chain I had a lot of links to drill. After making a divot to facilitate the hole I rubbed a candle stub over each divot for lubrication.” Thank you for sharing! There are proprietary lubricants like BurLife, PepeLube and Lube-Stik but using a candle is always an option as well. I love that we can share all the options on this page! Thanks Karla! #drillingmetal #drillingtip
