Premium-performance lubricant for drilling, reaming and tapping


  • Excellent extreme pressure and anti-wear performance
  • Maximises tool life in arduous operations
  • Available in liquid, paste and aerosol form


Molyslip TAP is a range of high-performance lubricants designed for severe metal working operations such as drilling, reaming and tapping. They are highly concentrated mixtures of lubricity and reactive extreme pressure and anti-wear additives.

Molyslip TAP products provide excellent surface finish to components and protect tooling from wear and damage. They are suitable for most drilling, reaming and tapping (spiral point, spiral flute and fluteless) operations on most metals. However, it is advised that compatibility is checked prior to use as the sulphurised extreme pressure additives may interact with some metals. For situations where chlorine must be avoided use TAP Chlorine-free, where both chlorine and sulphur must be avoided it is advised that TAP AQUA is used.

Molyslip TAP liquid can also be used to fortify flood-applied, neat-cutting oils, typical addition rates are 5-10% (check compatibility prior to addition).
