HOUGHTO-GRIND S 155 is a fully synthetic, specialist fluid for surface grinding of cemented tungsten carbide materials. The mineral oil-free, transparent solution provides long sump life and excellent tramp oil rejection.

HOUGHTO-GRIND S 155 is recommended for grinding of cemented tungsten carbide tools where cobalt is used as a binder.
The synthetic formula contains a special additive package to prevent dissolution of cobalt by the coolant. A minimum concentration of 5% is recommended.

o Rejects tramp oil completely – Excellent component visibility with no spoilage of coolant
o Inhibits dissolution of cobalt – reduces risk to workers and environment
o Outstanding low foam – no antifoam treatments necessary
o Contains lubricity additives – for longer wheel life and less viscous evaporation residues
o Rapid fines separation – excellent filterability with extended filter life
o Mineral oil, formaldehyde, chlorine, secondary amines and phenol -free – very good EHS profile
