A yellow-treated corrugated sisal brush, sized 400×150 mm (14 inch), consisting of 3 durable layers with a pleated and corrugated design, intended for cutting or initial polishing work on metal surfaces, especially when a balanced performance between hardness and softness is required.
🟡 The yellow treatment gives the sisal balanced properties that make it less aggressive than red brushes, yet more durable than white ones, making it ideal for the medium or foundational cutting stage on metal before final smoothing.
🌀 Its corrugated design helps provide continuous cooling during rotation, preventing surface overheating and maintaining polishing efficiency and finish quality.
✅ Recommended for use with the strong polishing compound C94 to achieve consistent results on stainless steel, aluminum, and other metals.
⚙️ Recommended speed range:
1400 – 1800 RPM
