Trefolex Cutting Paste is a green coloured, active cutting compound containing a colloid. It melts slowly as frictional heat is generated. It maintains efficient lubrication throughout operations such as pipe screwing, hack sawing, tapping and reaming. It is suitable for all users of hand tools. Trefolex Cutting Paste prolongs the life of the tool. It will not corrode steel nor affect aluminum. Although the surface of copper and brass is darkened, the metal suffers no detrimental effect. It is ideal for use with stainless steel.
