About Lubricants

Tapping and Threading Lubricants

Use these lubricants for easier and faster tapping, cutting, and threading of hard and thick material. They reduce friction between your cutting tool and workpiece to make cutting cycles faster and easier, improve surface finishes, and extend tool life.

Solid Tapping and Threading Lubricants

These easy-to-apply stick lubricants won't drip or run for a cleaner workspace. Use them for tapping many types of metal, as well as plastic and rubber. Apply to taps to make cutting faster and easier, improve surface finishes, and extend tool life.

Tapping and Threading Lubricants
for Aluminum and Copper

Formulated for use on soft metal, such as aluminum, copper, and brass, these lubricants won’t stain. They reduce friction between your cutting tool and workpiece to make cutting cycles faster and easier, improve surface finishes, and extend tool life.

Milling, Turning, and Sawing Lubricants

These general purpose lubricants reduce friction between your cutting tool and workpiece to make cutting cycles faster and easier, improve surface finishes, and extend tool life.

Milling, Turning, and Sawing
Lubricants for Aluminum and Copper

Also known as plumber's lard oil, these light-colored lubricants are chlorine and sulfur free, so they won't stain soft metal, such as aluminum or copper. They reduce friction between your cutting tool and workpiece to make cutting cycles faster and easier.

Milling, Turning, and Sawing
Lubricants for Stainless Steel

A high sulfur concentration provides the lubricity required to protect tools and stainless steel work surfaces, but these lubricants will stain other metal. They reduce friction between your cutting tool and workpiece to make cutting cycles faster and easier.

Solid and Paste Milling,
Turning, and Sawing Lubricants

Reduce mess and waste with these easy-to-apply, nonstaining lubricants. They reduce friction between your cutting tool and workpiece to make cutting cycles faster and easier, improve surface finishes, and extend tool life. All resist running and dripping.

Food Industry Milling, Turning,
and Sawing Lubricants

For use in food-processing and preparation areas, these lubricants are NSF registered H1 for incidental food contact. They reduce friction between your cutting tool and workpiece to make cutting cycles faster and easier, improve surface finishes, and extend tool life.

Machining and Fabricating Coolants

Milling, Drilling, and Turning Coolants

Dissipate heat and prevent corrosion with these coolants that stand up to long machining cycles when milling and turning.

Solid and Paste Milling,
Drilling, and Turning Coolants

An alternative to nearly dry machining, apply these coolants to tools before milling and machining to reduce heat with minimal cleanup. They’re often used for shallow drilling, reaming, and tapping, as well as on saw blades.

Milling, Drilling, and Turning
Coolants for Nearly Dry Machining

Apply just a few drops of these coolants to your cutting tools before and during milling and machining to reduce heat with very little cleanup.

Coolants for Drill Presses

Use these lubricants with magnetic-base drill presses to cool machining cycles, improving workpiece surface finishes and extending tool life.

Milling, Drilling, and Turning
Coolants for Micro-Drop Dispensers

For use with micro-drop dispensers, these coolants are mixed with air to create small, controlled droplets that dissipate heat and are easy to clean up. Use for small jobs.

Grinding, Sanding, and Finishing Coolants

For general-purpose grinding, sanding, and finishing, these coolants prevent material from building up to ensure a high-quality finish and preserve tool life.

Long-Life Grinding, Sanding, and Finishing Coolants

Increase the time between coolant changes—wear-resistant properties allow these coolants to perform longer than standard grinding coolants. They prevent material from building up to ensure a high-quality finish and preserve tool life.

Tapping and Threading Coolants

Designed to handle high pressure generated while tapping, threading, and reaming, these coolants dissipate heat and prevent corrosion to improve surface finishes and extend tool life.

Coolants for Welding Water Coolers

Weld longer without damaging your torch—replace the water in your welding cooler with these coolants to prevent mineral deposits and frozen lines. Coolants also tolerate colder temperatures than water. For use with MIG, TIG, spot, and stud welders. They are nonconductive.
