Model S2289-00 (shown at bottom right) is ideal for smaller parts and turning centers - with its 1 3/16" diameter roller and 9.5" overall tool length. This tool can burnish inside diameters as small as 1 3/8" and reaches up to 3" with an .031" radius roll. Model S2289A00 has an .093" radius roll.

The carbide roller is spring loaded in two axial directions to provide the correct pressure for burnishing.

**The carbide rolls can be reground several times as a tooling cost savings.
