FLEX-HONE GBD60018 Cylinder Hone, 6 Inch Bore, 180 Grit, Silicon Carbide
- The Brush Research GBD60018 Flex-Hone is a heavy-duty cylinder honing tool designed for 6 Inch bore diameter applications. Featuring a 6-1/4" abrasive section with 180 grit silicon carbide, it delivers a plateau-style cross-hatch finish ideal for improving lubrication retention, reducing leakage, and preparing sealing surfaces in engine blocks, hydraulic cylinders, and industrial bores.
- Features:
- Bead-style, flexible filament design with self-centering, self-aligning, and wear-compensating action
- 180 grit silicon carbide abrasive balances peak removal with preservation of oil valleys (approximately 30–40 µin Ra)
- Non-directional plateau cross-hatch pattern enhances seal performance and fluid retention
- Heavy-duty construction suitable for large bore applications in automotive and industrial environments

- The FLEX-HONE GBD60018 can also be referred to as 6" bore hone, GBD60018 flex hone, silicon carbide cylinder hone, plateau finishing brush, and heavy-duty bore tool.
Brush Research Manufacturing’s GBD-Series Flex-Hones are trusted in automotive, hydraulic, and industrial sectors for delivering consistent plateau-style finishes in large-bore applications.
Q: What bore diameter is this hone designed for?
A: The GBD60018 is engineered specifically for use in 6" bore diameter cylinders.
Q: What finish quality does the 180 grit provide?
A: It creates a plateau-style finish in the range of 30–40 µin Ra, ideal for sealing surfaces and oil retention.
Q: Can this hone be used with a handheld drill?
A: Yes—when used with drill presses or handheld drills, maintain speeds up to 600 RPM and use oil-based honing lubricant.
Q: What materials is this hone suitable for?
A: Effective on cast iron, carbon and stainless steels, and other ferrous materials commonly found in large-bore engine, hydraulic, and industrial cylinders.
Q: What lubricant should I use?
A: Use oil-based honing lubricant to protect the abrasive bond and achieve consistent finish quality.
