Introducing the Jaz Cup Brush High Performance BRUC-125H — a purpose-built cup brush engineered for portable machines, including electric and pneumatic angle grinders. With a 125 mm diameter and a 30 mm trim, it delivers concentrated brushing action exactly where you need it, offering a focused, medium-removal profile for efficient surface prep.

Created for versatility, BRUC-125H is designed to handle rust, old paint, and stubborn adherents on metallic surfaces, while also offering cleaning potential on rubber, plastic, wood, and glass when appropriate for the task. What makes it stand out is the breakthrough cable-crimped wire construction — instead of traditional single filaments, this brush uses grouped wires that form crimped cables. Each cable packs several 0.23 mm high-resistance steel wires, delivering a flexible, compact, and aggressive brushing action that stays true across uneven contours.

What sets BRUC-125H apart

• Cable-crimped wire design — multiple-wire cables provide improved conformity to curved edges and irregular surfaces, reducing chatter and wire shedding while maintaining aggressive material removal.
• Focused, large-surface brushing — specifically optimized for high-efficiency rust and paint removal over broad areas without sacrificing control.
• High-strength materials — 0.23 mm coating-on steel wires offer durability and consistent performance under heavy-use conditions.
• Broad compatibility — built for portable grinders with M14 x 2 mounting threads, making it a versatile choice for a wide range of tools and setups.
• Versatile surface prep — while particularly effective on metallic surfaces, it can be used for treating and cleaning various materials when the task requires careful, controlled brushing.

Ideal uses and scenarios

• Rust and paint removal on automotive chassis, frames, and metal panels during restoration or maintenance.
• Surface preparation for coating, plating, or welding where a clean, ready-to-coat surface is essential.
• Cleaning and deburring of metalwork, fabrication components, and machinery surfaces with a wide brushing footprint.
• Light material removal on metal, with potential applications on rubber, plastic, wood, or glass where gentler, controlled brushing is appropriate.

For best results, pair the BRUC-125H with a compatible portable grinder set to appropriate speeds. Maintain a steady, even pressure and keep the tool at a consistent angle to maximize contact with the surface. Regularly inspect the brush for wear and replace when the wires begin to shed or lose integrity. If you’re tackling large-scale rust removal, coating prep, or surface cleaning projects, this high-performance cup brush delivers rapid, reliable results with a distinct edge over traditional single-filament designs.
