Hangsterfer’s S 500CF – A Proven, High-Performance Soluble Coolant That Just Works

by Bernard Martin

S 500CF is a long-established soluble coolant built for consistent machining performance,
long sump life, and reliability in CNC shops.

Some coolants show up with a lot of marketing noise and disappear a few years later. Others quietly earn their place and just keep running. S 500CF from Hangsterfer’s Metalworking Fluids falls into that second category.

This is not a “new formula” coolant, and that’s actually part of its strength. S 500CF is built on a mature, well-established soluble coolant chemistry that has been refined over decades of real-world machining. Long before water-soluble coolants became common in North American shops, this formulation approach was already being proven in demanding production environments.

When Hangsterfer’s expanded beyond straight cutting oils into soluble coolants, S 500 was one of their first coolant offering and soon there after the "chlorine free" or "CF" variant was developed. That foundation gave them a solid starting point—and it shows in how S 500CF performs today.

At its core, S 500CF is a chlorine-free, water-soluble coolant designed to be easy to live with on the shop floor. It’s non-corrosive, non-toxic, and operator friendly, which matters when machines are running multiple shifts and sumps stay charged for long periods. From a management standpoint, it simplifies coolant selection by covering a wide range of machining operations without needing multiple products for different machines.

Material flexibility is one of the reasons shops stick with it. Hangsterfer’s S 500CF performs consistently in aluminum, carbon and alloy steels, and stainless steels, and it holds up when you move into tougher materials like titanium, nickel-based alloys, and powdered metals. Whether you’re milling, turning, drilling, or tapping, it delivers reliable lubrication and cooling without constant tweaking.

Sump life is another area where this coolant quietly earns its keep. The formulation is stable, resists bacterial growth, and rejects tramp oil well. That means fewer odor issues, cleaner machines, and less time spent chasing coolant problems instead of making parts. For shops running central systems or machines that don’t get drained often, that stability becomes a real cost saver over time.

Day to day, S 500CF doesn’t demand much attention. Mix it correctly, monitor concentration with a refractometer, skim tramp oil, and it stays predictable. That predictability translates directly into consistent surface finish, better tool life, and fewer surprises when jobs change or materials rotate through the shop.

Hangsterfer’s reputation was originally built on straight cutting oils during World War II, where performance and reliability mattered more than marketing claims. That same mindset carries through in S 500CF. It’s a coolant designed to work, stay stable, and support machining operations without becoming a problem of its own.

For shops looking for a proven, high-performance soluble coolant that’s been tested by time rather than trends, Hangsterfer’s S 500CF remains a dependable option.  For more information on Hangesterfer's products get in touch with our team at Factory Tooling Solutions and we can help you with testing as well as on site tech support.
