Stainelec ApprovedCutting Compounds - Trefolex Cutting Fluids

Manufactured by CRC, Trefolex is a green coloured active cutting compound containing a dispersal colloid.

It melts slowly as frictional heat is generated. It maintains efficient lubrication when applied to the SEK hole saw blades. It is suitable for use on aluminum, mild steel and stainless steel material.

Trefolex prolongs the life of the cutting teeth whilst not affecting the material its cutting when applied. It will not corrode steel or affect aluminium surfaces .

We recommend the use of high quality cutting compounds when using the SEK hole saws as it will increase the longevity of the blades cutting teeth when working on thicker steel materials.
