BALL HONE 1 1/4" - OTC Tools and Equipment

The OTC 7011-8 Ball Hone is a precision abrasive tool engineered for professional-grade cylinder bore finishing. Designed to create an ideal cross-hatch pattern, this 1 1/4" (32mm) diameter hone effectively deglazes cylinder walls, preparing surfaces for optimal ring seating and oil retention in various automotive and industrial applications. Its flexible design ensures consistent contact and a superior finish, crucial for component longevity and performance.

Key Features

• 1 1/4" (32mm) Diameter: Perfectly sized for a range of smaller bores, including brake and hydraulic cylinders.
• Self-Centering Design: The flexible shaft and abrasive globules conform to the bore, ensuring even pressure and a consistent finish throughout.
• Produces Optimal Cross-Hatch Pattern: Creates the preferred plateau finish necessary for effective lubrication and sealing of piston rings.
• Professional-Grade Abrasives: Constructed with durable abrasive media designed to withstand repeated use in demanding workshop environments.
• Enhanced Component Life: Proper bore finishing reduces wear and tear on mating components, extending the service life of rebuilt assemblies.

Applications

The OTC 7011-8 Ball Hone is an essential tool for technicians performing rebuilds and maintenance on systems requiring precise bore finishing. Common applications include deglazing and finishing the bores of automotive brake master cylinders and wheel cylinders, ensuring proper sealing and brake fluid pressure. It is also suitable for small hydraulic cylinders found in industrial equipment, motorcycle engine cylinders, and other applications where a critical surface finish is required for optimal performance and fluid retention. This tool helps ensure components operate efficiently and reliably after servicing.
