Wire cup brush 120 mm with M14 thread — steel wire filaments, model SZ TG 120

Wire cup brush 120 mm with M14 thread — steel wire filaments, model SZ TG 120 is a 120 mm diameter cup-style wire brush designed for attachment to angle grinders and compatible rotary tools with an M14 threaded arbor. The brush uses steel wire filaments arranged in a compact cup shape to provide a controlled contact area for removing rust, paint and scale, preparing metal surfaces and deburring edges. Its construction suits workshop and construction tasks where reliable mechanical cleaning and surface preparation are required.

Advantages

The steel wire filaments deliver aggressive but predictable material removal on ferrous surfaces and welded joints. The cup shape concentrates brush action for accessible cleaning of seams, welds and corners while reducing the risk of excessive contact on flat surfaces. The M14 threaded connection ensures straightforward mounting on a wide range of angle grinders and rotary tools. The 120 mm diameter balances working area and maneuverability, offering efficient coverage without compromising control.

Suitable for

• Removing rust and scale from steel surfaces
• Stripping paint and coatings from metal
• Cleaning and preparing welds and joints
• Light deburring and edge blending on metal parts
• Surface preparation prior to painting or coating

Key specifications

• Brush diameter: 120 mm
• Filament material: steel wire
• Brush shape: cup
• Arbor/thread type: M14 threaded connection
• Typical applications: rust removal, paint stripping, weld cleaning, deburring

How to use

Mount the wire cup brush securely on an angle grinder or compatible rotary tool using the M14 thread, following the tool manufacturer's instructions for installation and tightening. Always verify the brush is centered and rotates freely before powering the tool. Operate the grinder at the recommended speed range for wire cup brushes, applying steady, even pressure while moving the brush across the workpiece. Use controlled passes to avoid gouging or overheating the surface; allow the brush filaments to do the cutting rather than forcing the tool.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, gloves and respiratory protection when generating dust or particles. Use in well-ventilated areas. Inspect the brush for wear, loose filaments or damage before each use and replace when performance degrades. Avoid using the brush on non-ferrous or soft materials where steel filaments could cause contamination or damage; choose a suitable filament type for such tasks.
