1GAL (3.78L) Rapid Tap Cutting Fluid for All Metals

The Relton RT4 Rapid Tap Cutting Fluid is a professional-grade metal cutting fluid designed to improve tool performance and precision across a wide range of metalworking applications. This 1-gallon (3.78L) container provides excellent value for high-use environments, and the fluid’s advanced formula is engineered to reduce friction, manage heat, and prolong tool life. Whether you’re cutting, drilling, tapping, or threading, this non-toxic, ozone-safe lubricant delivers cleaner, smoother results—especially on hard-to-machine metals like stainless steel, molybdenum, and Stellite. While it’s safe for aluminum, users focused solely on aluminum may benefit more from a dedicated aluminum-specific solution.

Its anti-mist formula supports a healthier workplace by limiting airborne particles, meeting safety requirements without the need for special labeling. The Rapid Tap formula is ideal for operations requiring clean, accurate cuts on challenging materials—making it a go-to solution for demanding jobs in machining, heavy-duty fabrication, or specialized production work.
