A blue-treated corrugated sisal brush, sized 400×150 mm (14 inch), made of 3 durable layers, used for medium cutting or smoothing stages on metals, especially when a balance between strength and control is required.
🔵 The blue treatment gives the sisal improved hardness with less friction than the red type, making it suitable for applications that require medium preliminary smoothing without leaving a rough effect on the surface.

🌀 The corrugated design provides continuous ventilation during operation, preventing overheating, improving efficiency, and extending service life.

✅ Recommended for use with C94 polishing compound, especially when working on stainless steel and hard metals.

⚙️ Recommended speed range:
1400 – 1800 RPM to ensure the best balance between performance and professionalism.
