Cup Brushes
Abrasive cup brushes are essential tools for removing rust, scale, and other surface contaminants from metal and other hard materials. They consist of a metal cup with abrasive filaments securely attached. These brushes are typically used with power tools like angle grinders or drill and die grinders.
Types of Cup Brushes
- Knotted cup brushes: These brushes have filaments that are knotted together at the base, providing a more aggressive cleaning action. They are ideal for heavy-duty applications like removing thick rust or scale.
- Crimpled cup brushes: These brushes have filaments that are crimped into the cup, resulting in a softer and more flexible brush. Crimpled cup brushes are better suited for delicate cleaning tasks or finishing work.
Abrasive Materials
- Carbon steel cup brushes are a common and affordable option, carbon steel brushes are suitable for general-purpose cleaning and removal of light to medium rust.
- Stainless steel cup brushes are more resistant to corrosion and are ideal for use in wet environments or when working with stainless steel materials.
- Tempered steel cup brushes offer a balance of strength and flexibility, making them suitable for a wide range of applications.
- Brass cup brushes are softer than steel brushes and are often used for finishing work or removing light rust without damaging the base material.
Compatible Power Tools
- Angle grinders are the most common tool for using cup brushes. They provide high power and speed for efficient cleaning. Cup brushes for angle grinders connect by a threaded arbor.
- Drill and die grinders offer more control and maneuverability, making them suitable for smaller or more intricate cleaning tasks. Cup brushes for drill and die grinders connect with a hex shank.
