GB 3 3/4" 95MM 120SC FLEX - Brush Research

The Brush Research GB33412 Flex-Hone is a professional-grade honing tool designed for superior surface finishing and deburring of cylinders. With its 3-3/4 inch (95mm) diameter and 120 grit silicon carbide abrasive, this standard-duty flexible hone is engineered to deliver a consistent, plateaued finish and an optimal oil-retaining crosshatch pattern in a variety of bore applications. It is an essential tool for technicians and mechanics seeking to enhance component performance and longevity.

Key Features

• Advanced Silicon Carbide Abrasive: Features 120 grit silicon carbide globules, ideal for efficiently deglazing and finishing cast iron, mild steel, and stainless steel cylinders.
• Flexible, Self-Centering Design: The flexible construction allows the tool to be self-aligning, self-centering, and self-compensating for wear, ensuring a consistent finish even in bores with minor irregularities.
• Optimal Plateau Finish: Creates a true plateau finish by removing peaks from previous machining operations, which promotes improved piston ring seating, better oil control, and reduced break-in time.
• Deburring Capabilities: Effectively removes burrs from cross-drilled holes, leading to cleaner part intersections and improved operational safety and functionality.
• Professional-Grade Durability: Manufactured by Brush Research, a trusted name in surface finishing solutions, ensuring high quality and reliable performance in demanding professional environments.

Applications

The GB33412 Flex-Hone is highly versatile and widely used across numerous professional applications. It is particularly effective for deglazing and surface finishing engine cylinders and liners in automotive, heavy-duty diesel, and industrial engines. This tool also excels in preparing cylinder walls for piston ring replacement and engine rebuilds, ensuring optimal ring seal. Beyond internal combustion engines, its capabilities extend to deburring and finishing in hydraulic and pneumatic cylinders, firearm components, and various general industrial and manufacturing applications where internal bore quality is critical.
