Brush Research Manufacturing’s Flex-Hone® oil is specially formulated with a unique blend of honing and lapping oils, a moisture dispersant, a lard oil to prevent galling of aluminum, a non-ionic surfactant wetting agent, and a special additive to help keep metal cutting and contaminants in suspension. The oil is emulsified and contains an anti-bacteria agent for reliable, long-term performance in your gunsmithing work.

This petroleum-based formula will not harm aluminum, brass or steel, and proper use of Brush Research’s Flex Hone Oil is essential—use of other oils destroys the abrasive ball and voids the guarantee. when working with finer surface tolerances, better quality honing fluids are required to achieve the smooth, accurate honing operations that professional gunsmiths demand.

Flex-Hone® oil is available in 1/2 pint, quart, gallon, and 5 gallon plastic containers. The 1/2 pint size provides a convenient, compact option for shooters and gunsmiths who want to keep the correct lubricant on hand for maintenance and refinishing work.
