Restore Cylinder Performance with Professional-Grade Honing
The Cylinder Honing Ball Brush (4.125" / 105mm Diameter, 240 Grit Silicon Carbide) is a flexible, resilient honing tool designed to restore and improve internal cylinder surface finishes. Whether you're rebuilding an engine, servicing hydraulic equipment, or refinishing brake cylinders, this ball-style hone delivers professional results every time.
Features
Abrasive Technology
The 240 grit silicon carbide abrasive create hundreds of cutting points that conform naturally to your cylinder's surface. This design ensures even material removal without altering the original bore geometry or accuracy.
Self-Centering Action
This flexible hone automatically centers itself within the bore. The abrasive balls float and adjust to compensate for wear, maintaining consistent pressure and finish quality throughout the life of the tool. This makes it ideal for both experienced machinists and DIY enthusiasts.
Applications
Engine cylinder walls and engine blocks
Hydraulic and pneumatic cylinders
Brake cylinders and wheel cylinders
Compressors and pumps
Valve bodies and valve guides
Industrial deburring and surface finishing
