Customer Questions & Answers

  • Question: What is the purpose of the Brush Research GB312600 FLEX-HONE®?

    Answer: The Brush Research GB312600 FLEX-HONE® is designed to provide surface finishing and conditioning for various metals, particularly mild steel, stainless steel, and cast iron. It effectively deburrs edges, removes small imperfections, and creates a fine surface finish. This is crucial for applications where a smooth surface is required, such as in engine components or hydraulic cylinders, enhancing overall performance and longevity.
  • Question: What types of materials can I use the FLEX-HONE® on?

    Answer: The FLEX-HONE® is perfect for working with mild steel, stainless steel, cast iron, and softer ferrous materials. Its silicon carbide construction allows it to tackle a variety of surfaces while maintaining its integrity. This versatility makes it an ideal tool for metalworkers and machinists who work with multiple materials, ensuring a consistent finish across different projects.
  • Question: How do I install the FLEX-HONE®?

    Answer: Installing the FLEX-HONE® is straightforward; it can be used with a standard drill or rotary tool. Ensure that the tool is set to the appropriate speed, usually between 200 to 500 RPM, depending on the material you're working with. Align the hone with the surface and use a smooth in-and-out motion for even coverage. This method ensures optimal performance and extends the life of the tool while providing high-quality results.
  • Question: What is the grit size of this FLEX-HONE® and how does it affect performance?

    Answer: The GB312600 FLEX-HONE® features a 600 grit size, striking a balance between aggressive material removal and achieving a fine finish. This grit is particularly effective for honing purposes where a smoother surface is needed. In contexts such as valve guides or cylinder bores, this level of fineness aids in reducing friction and maintaining efficient engine performance over time.
  • Question: Can the FLEX-HONE® be used on non-ferrous metals?

    Answer: While the FLEX-HONE® excels on ferrous metals like mild steel and stainless steel, it can also be used on some non-ferrous metals, although its effectiveness varies. Users must consider the material's hardness when employing the hone. For aluminum or brass, lighter touch and adjustments in technique may be necessary to avoid potential damage or excessive wear of the tool.
  • Question: What maintenance does the FLEX-HONE® require after use?

    Answer: After using the FLEX-HONE®, it's essential to clean it to ensure optimal performance for future applications. This can be done by rinsing it with water or using a brush to remove any debris or buildup. Proper maintenance helps in preserving the grit and extends the lifespan of the tool, making it a reliable option for consistent quality in upcoming projects.
  • Question: Are there any specific safety measures to take while using the FLEX-HONE®?

    Answer: Yes, using the FLEX-HONE® safely involves wearing appropriate personal protective equipment, including safety goggles and gloves. Ensure that your workspace is well-ventilated and clear of obstructions. Additionally, always inspect the tool before use to avoid accidents. Following these precautions not only protects you but enhances the overall effectiveness of the honing process.
  • Question: What is the diameter specification of the FLEX-HONE®?

    Answer: The Brush Research GB312600 FLEX-HONE® has an 89mm diameter, suitable for various applications like honing engine cylinders or hydraulic components. This size is designed to efficiently address different bore sizes while providing the ability to maneuver easily. Being able to access tighter spaces makes this tool particularly valuable for automotive or machine shop environments.
  • Question: Can the FLEX-HONE® be used with power tools other than drills?

    Answer: Certainly! The FLEX-HONE® can be utilized with various power tools, such as pneumatic or electric flex-shaft tools, enhancing versatility in operations. Depending on your workspace setup, this adaptability allows users to choose the best tool to achieve their desired surface finish while ensuring smooth operation across multiple types of applications.

Flex-Hone Flex Hones Editorial Review

The Brush Research FLEX-HONE Cylinder Hone is an excellent choice for refreshing a block, honing out scratches and score marks, and re-honing a cylinder. It comes in a variety of sizes, from 4mm to 14 inches, and has a range of grits from 60 to 600. The silicon carbide abrasive is of high quality, and the honing process is quick and easy, providing a perfect crosshatch. The larger models can be used over a broad area of bores, and they are an improvement over older honing tools. However, some caution must be taken when using this product to ensure the correct size is being used, or it may cause problems.
