Hammer Grease

---

Preventing premature tool and tool bushing wear requires a sufficient supply of the correct grease to the tool. The tool must be pressed against a hard surface until it stops up inside the hammer. This ensures proper distribution of grease between the tool and tool bushings.

The type of grease used is very important. NPK recommends a Lithium Base, Moly (Molybdenum Disulfide) or other surface protecting additives, EP (Extreme Pressure), NLGI #2 grease. A high drop point (500°F, 260°C) grease is desirable.

 

NPK Grease

It is imperative that special lubricants be used in your NPK hammer to protect the main components.  NPK now offers hammer grease specially formulated to meet severe job requirements.  The grease is available with various temperature ranges.  NPK grease products contain additives that resist extreme pressures and heat.  Our specially formulated moly-based grease and chisel paste are available through your local NPK dealer.
