FLEX HONE GBD 3-1/2 120SC - Brush Research

The Brush Research FLEX HONE GBD 3-1/2 120SC is a heavy-duty flexible cylinder hone engineered for professional surface finishing and deburring in 3-1/2 inch bores. Crafted with durable silicon carbide abrasive, this tool is designed to deliver a consistent, high-quality plateau finish, optimizing component performance and longevity. It is an indispensable tool for technicians and mechanics seeking to improve critical surface integrity.

Key Features

• Self-Centering and Self-Aligning: The unique construction allows the tool to be self-centering and self-aligning to the bore, eliminating the need for elaborate or rigid setups and enabling use in both online machine tool applications and as a secondary operation.
• Optimal Surface Finishing: Effectively reduces Ra, Rk, and Rpk values while maintaining the Rvk and Vo volume necessary for superior oil retention, crucial for moving parts.
• Efficient Deburring: Removes burrs from cross-drilled holes, creating clean, radiused intersections. A forward and reverse rotation technique ensures a symmetrical deburring pattern.
• Advanced Plateau Finishing: Pioneers the concept of a plateau finish by removing machining peaks, creating a substantially flat surface that allows rings and seals to seat without damage. This cross-hatch pattern aids in lubrication control, reduces seepage in hydraulic and pneumatic applications, and promotes extended seal life.
• Heavy-Duty Construction: As a GBD series tool, it features a longer abrasive length compared to standard hones, providing more abrasive material for enhanced durability and making it suitable for larger diameter or high-production applications.
