GBD 3 1/4" 83MM 240SC FLEX HON - Brush Research

The Brush Research GBD 3 1/4" 83MM 240SC FLEX HON is a heavy-duty, professional-grade flexible honing tool engineered for superior bore finishing in demanding automotive and industrial applications. This specialized tool delivers a consistent plateau finish, crucial for optimizing component longevity, improving lubrication retention, and ensuring effective sealing in cylinders and other critical bores.

Key Features

• Heavy-Duty Construction: Part of the GBD Series, this hone features a longer abrasive length, providing more abrasive material for extended tool life and robust performance in high-production or large-diameter applications.
• Precision Surface Finishing: Utilizes 240 grit Silicon Carbide abrasive globules, ideal for efficiently removing torn and folded metal while creating an optimal plateau finish with an oil-holding cross-hatch pattern.
• Self-Centering Design: The flexible, self-centering, and self-aligning construction ensures uniform pressure against the bore wall, delivering a consistent finish and compensating for wear without complex setups.
• Versatile Abrasive: Silicon Carbide (SC) abrasive is highly effective on various materials including mild steel, stainless steel, cast iron, and other softer ferrous components.
• Made in the USA: Manufactured with professional-grade quality and reliability in the USA.

Applications

This flexible hone is an essential tool for technicians and mechanics seeking to enhance the performance and lifespan of internal components. Common use cases include:

• Deglazing and finishing automotive engine cylinders, including those in passenger cars, light trucks, marine engines, and small engines.
• Honing hydraulic and pneumatic cylinder bores to reduce leakage and improve seal performance.
• Preparing brake caliper bores for rebuilding and other brake system maintenance.
• Deburring cross-drilled holes and conditioning various industrial bores for optimal function and reduced friction.
