Koolmist formula 77 coolant the improved formula “77” is highly recommended for mistcooling any metal or alloy where tougher machining condtions require greater lubricity. It is particularly useful where tool pressure is exceptionally great or where the material is very abrasive. Formula “77” provides the extra lubrication needed to protect the cutting edge of the tool. Formula “77” has been reformulated to provide the same safety for use as formula “78” where incorporating additional lubricity ingredients for more demanding machining applications. In addition, formula “77” provides excellent service in most general purpose flood cooling applications. One coolant-formula “77” – will fill most of your general mist and flood coolant needs. Formula “77” eliminates double coolant inventory, cuts storage space requirements and reduces your costs.
