Keeping cool is no problem with our cooling spray for core drilling applications - and this is not only applying to core drills from Alfra. Extend the service life of your tools and benefit from easier workflows for drilling, tapping, reaming, countersinking and demanding machining. Further advantages: As a pump spray, Alfra 4000 requires no propellant gas and is therefore ideal for drilling and threading high-alloy steels, chrome-nickel steels, or titanium and manganese-carbon steels. It meets all requirements of occupational safety and hygiene.
