20L Houghton (Shell) Dromus B
Houghton Dromus B is a general purpose water soluble oil for light to moderate duty machining on a wide range of materials.
This oil should be mixed with water to form a white emulsion. The mixture, commonly known as 'suds', can be applied manually to the metal being cut, or fed from a machine based coolant pump system.
The recommended concentration for general machining is 6-8%, although it can be used in higher concentrations for difficult machining tasks. The following can be used as a guide to concentrations
- Add 1L Dromus B to 7L water = 8L Coolant @ 12.5%
- Add 1L Dromus B to 9L water = 10L Coolant @ 10%
- Add 1L Dromus B to 11L water = 12L Coolant @ 8%
- Add 1L Dromus B to 13L water = 14L Coolant @ 7%
- Add 1L Dromus B to 15L water = 16L Coolant @ 6%
- Add 1L Dromus B to 17L water = 18L Coolant @ 5.5%
- Add 1L Dromus B to 19L water = 20L Coolant @ 5%
