BONDERITE® Machining Coolants 101
Performance Machining Fluids
Metal manufacturing is an enormous and varied industry - requiring specialty lubricants to maximize production and protect workpieces, machine tools and optimize safety in the shop itself. Henkel strives to provide best-in-class performance for all of these factors in the Bonderite® Metalworking Lubricant portfolio. Dive deeper into the pros and cons of metalworking coolant types and feel more confident in selecting the ideal solution for your operation.
What are Machining Coolants?
Machining coolants are specially engineered lubricants that provide protection for workpieces and machine tools by controlling friction, reducing extreme temperatures, protecting from corrosion & rust, and physically removing metal chips & flakes.

Types of Machining Coolants
There are four main types of metalworking fluids – Straight Oil, Soluble Oil, Semi-Synthetic and Synthetic Fluids. Each of the metalworking coolant types provide their own specific benefits and disadvantages for use and it’s important to understand which type of fluid is right for your machining operation.
