The Brush Research FLEX-HONE GB Series is a 3.5-inch diameter flexible abrasive cylinder hone featuring 120 grit silicon carbide beads. Designed for precision surface finishing and cross-hole deburring, it self-centers, self-aligns, and compensates for wear, making it easy to use by hand or CNC. Suitable for a wide range of cylinder sizes and materials, it delivers a plateau finish that improves oil retention, seal life, and overall component performance.
