Sanding disc Metabo 624123000 for metal 18 cm 8500 RPM

The Metabo 624123000 sanding disc for metal is a circular abrasive designed for surface preparation and finishing on steel, stainless steel and non-ferrous metals. With an 18 cm diameter and a 2.22 cm bore, this disc mounts on compatible rotary sanders and delivers consistent material removal at working speeds up to 8500 RPM. Supplied in a pack of 25, the discs support continuous operation in workshop and on-site environments, providing even wear and predictable performance for grinding, deburring and surface blending tasks.

Advantages

These sanding discs are specifically formulated for metalworking, combining abrasive grit and backing strength to maintain shape and cutting action under load. The 18 cm diameter gives a larger contact area for faster stock removal compared with smaller discs, while the 2.22 cm bore fits a wide range of standard tool adapters. Rated for up to 8500 RPM, the discs are suitable for high-speed rotary sanders without premature failure. Pack quantities of 25 reduce downtime by ensuring replacement discs are readily available.

Suitable for

• Sanding and smoothing weld seams on steel and stainless steel
• Removing rust and scale from metal surfaces
• Deburring edges after cutting or machining
• Surface blending and preparing metal for painting or coating
• Light stock removal and finishing on non-ferrous metals

Key specifications

• Intended material: metal (including steel, stainless steel, non-ferrous metals)
• Disc diameter: 18 cm
• Bore diameter: 2.22 cm
• Maximum permissible rotational speed: 8500 RPM
• Pack quantity: 25 discs

How to use

Ensure the sanding disc and tool are compatible by confirming the 2.22 cm bore aligns with the machine’s spindle or adapter. Mount the disc securely according to the sander manufacturer’s instructions and verify the disc is centered. Start the tool at low speed to check for runout or vibration, then increase speed up to the safe working limit, not exceeding 8500 RPM. Apply consistent, moderate pressure and move the disc along the workpiece to avoid gouging; allow the abrasive to do the work rather than forcing the disc. Replace discs when grit is worn or performance declines.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, gloves and a dust mask. Use proper machine guards and ensure the workpiece is secured. For best results on welded joints and heavy rust, begin with a coarser grit disc and progress to finer grits for finishing. Store discs flat in a dry environment to prevent deformation.
