The aim of near dry machining is to replace traditional coolant and pure oil flood systems in a machining environment with an accurately controlled compressed air stream that carries minimal quantities of oil lubrication in an "aerosol" format to the cutting surface. This ensures lubrication of the cutting surface and allows for high performance machining.

Lubricating Aerosol is transported to the cutting surface in two ways:
 
With External Lubrication: oil is transported via a nozzle to the cutting surface.
Dropsa has a complete product line from simple, easy to install products such as the Grip and Vip4Tools series for External lubrication.

With Internal or "through-the-tool" lubrication: oil is transported through internal lubrication holes in the cutting tools.
The MKD-Dual product leads the way with patented technology that generates specifically profiled micron-sized oil aerosol particles that can be injected through existing spindles and tool-holders to the leading edge of the cutting tool.
