Lubrication whilst drilling or threading on the lathe is often overlooked, or if not overlooked is often done with lubricants that aren't necessarily the wisest choice.
Shield Technology is a small company based in the UK, who despite their small size are market leaders in rust prevention. Their boss also happens to be a pen maker and a customer of ours, and they have formulated a bespoke lubricant specially for pen makers, that will also inhibit rust on the tool itself.
