What Is a Split Mandrel Used For?

A split mandrel converts a strip of sandpaper or abrasive paper into a small rotary sanding tool. The abrasive strip is inserted into the slot and wrapped around the mandrel.

When rotated in a suitable handpiece, the abrasive can be used for:

• Smoothing metal surfaces
  
• Removing scratches and surface marks
  
• Deburring edges
  
• Surface preparation
  
• Refining jewellery components
  
• Cleaning up after filing or fabrication
  
• Preparing surfaces before further finishing or polishing
  
• General precision sanding

How to Use

Cut a suitable strip of sandpaper or abrasive paper and insert one end into the split in the mandrel.

Wrap the abrasive strip around the mandrel in the appropriate direction, ensuring it is positioned securely. Fit the mandrel into a compatible rotary handpiece and use it for controlled sanding and finishing.

As the abrasive becomes worn, simply replace the strip. Different abrasive grits can be fitted depending on whether more aggressive material removal or finer finishing is required.
