Heavy Duty Bore-Hone™ Brushes
Tanis Heavy Duty Bore Hone Brushes are built for tough honing jobs where aggressive material removal is required. These brushes feature stiffer filaments and a denser abrasive load, making them ideal for diesel engine blocks, industrial cylinders, and surfaces with carbon, rust, or heavy buildup.
