The Tjap MATA / Carl Schlieper bowl brush is an accessory for hand grinders used for removing heavy dirt, rust, paint, and surface preparation on metal, wood, or concrete.

Specifications and Key Features
Tjap MATA bowl brush is known for its durability and high-quality wire. This product is available in several varieties based on wire material and gauge:
