EN5 The Drilex standard even-thickness rotor coating is the EN5 formulation. It is an economical coating that is used in light duty applications where corrosion is not a concern. It has good wear resistance and can be applied to either an alloy or stainless steel substrate. Like chrome, EN5 can be easily stripped and reapplied to prolong the life of the rotor.
SR2 The Drilex SR2 coating is a direct replacement for chrome. Unlike chrome, it is applied with an even thickness to minimize rotor profile distortion. This coating offers good performance and life in most types of light to medium duty applications.
XR3 The Drilex Extreme Rotor Coating (XR3) is a proprietary, even-thickness, tungsten carbide coating suitable for use in medium to severe applications. XR3 offers outstanding wear protection and is excellent for use in high chloride applications. Additionally, this type of coating performs very well in pneumatic applications with very little lubrication. With a coefficient of friction less than typical chrome plating, XR3 can significantly extend stator life over other types of coatings. The XR3 coating is an excellent heavy duty coating that does not require a stainless steel substrate.
