Specifications

Precision Cleaning for Metal Surfaces

The fine fiberglass bristles provide localized abrasive action for cleaning small metal surfaces and components. This makes the brush especially useful when a larger conventional scratch brush would be difficult to control.

Use it to remove rust, dirt, oxidation, and surface contamination from compatible metal parts or for light surface refinement and polishing during repair and restoration work.

Adjustable Screw-Feed Design

The screw-feed holder allows you to control the amount of fiberglass bristle exposed during use.

As the fibers wear down, additional bristle material can be advanced from inside the holder. This keeps the tool useful throughout the life of the insert and eliminates the need to replace the complete holder when the exposed fibers become worn.

Replaceable Fiberglass Refills

When the original fiberglass insert is used up, replace it with Grobet 16.333 Fiberglass Brush Refills, available separately as a set of two.

This replaceable design makes the 16.332 a practical tool to keep at the bench for routine cleaning and restoration work.

• Watch and clock repair
• Camera and optical repair
• Precision mechanical repair
