HD Flex-Hone Tool - 8 In - 20 Grit - Brush Research

The Brush Research GBD820 HD Flex-Hone Tool is an essential solution for professional technicians requiring a high-quality surface finish in various bore applications. This 8-inch, 20-grit silicon carbide honing tool is engineered for heavy-duty use, providing consistent and reliable results in automotive and industrial settings.

Key Features

• Heavy-Duty Construction: Designed for demanding professional environments, ensuring durability and extended service life.
• Optimal Bore Conditioning: The 20-grit silicon carbide abrasive delivers a controlled, soft cutting action, ideal for deglazing, cross-hatching, and improving surface finish in cylinders and other bores.
• Self-Centering and Self-Aligning: Equipped with independently suspended abrasive globules, the Flex-Hone automatically centers itself, aligns to the bore, and compensates for wear, ensuring uniform material removal and consistent finish.
• Flexible and Resilient Design: Conforms to bore irregularities, providing a comprehensive and efficient honing process.
• Extended Reach: Features a robust 1/2" hex shaft with an overall length of 34", allowing access to deeper or less accessible bores.

Applications

This heavy-duty Flex-Hone tool is widely used for preparing cylinder walls for new piston rings, improving sealing surfaces in hydraulic cylinders, and deburring machined holes. It is suitable for a range of automotive engine rebuilds, brake caliper reconditioning, and industrial machinery maintenance where a precise and consistent bore finish is critical for performance and longevity.
