The long-awaited grinding and polishing dedicated model has arrived in the Rising Sun series! Magic Coolant was born as a completely new third option compared to the traditional cutting oils, which offered two choices: oil-based and water-soluble. Magic Coolant 'Rising Sun GD' meets the needs of users who want to use oil-based coolant but are concerned about fire hazards, as well as those who want to use water-soluble coolant but experience poor surface roughness and tool life, leading them to use oil-based options instead. It offers lubrication performance equivalent to oil-based coolants and cooling performance equivalent to water-soluble coolants, providing very high machining performance that improves tool life and surface roughness. Since it can be cleaned with water, there is no need for hydrocarbon-based cleaning solutions, resulting in cost savings.
