Flap Disc 40x20x6 mm P40 GEKO — radial mounted abrasive for metal and wood (pack options 50/100)

GEKO flap disc 40x20x6 mm P40 is a radial-mounted abrasive designed for use on spindles to perform grinding, material removal and finishing on metal and wood. The disc combines multiple overlapping abrasive flaps to provide consistent stock removal while maintaining a controlled finish. Available in pack sizes of 50 or 100 pieces, this abrasive is intended for workshop and industrial use with compatible spindles and appropriate safety equipment.

Advantages

The flap construction ensures even wear and predictable cutting action across the working surface, reducing vibration compared with some rigid abrasives. P40 grit offers an aggressive cutting rate suitable for deburring, edge rounding and rapid material removal. The small 40x20x6 mm format is compact and appropriate for detail work, tight spaces, and fixtures where larger discs cannot be used. Supplied in bulk packs to facilitate repeated operations and reduce downtime for replacement.

Suitable for

• Removing rust and scale from metal surfaces
• Deburring edges and weld seams
• Shaping and smoothing wooden workpieces
• Surface blending and preparing substrates for coating
• Detail grinding in confined or hard-to-reach areas

Key specifications

• Disc dimensions: 40 x 20 x 6 mm
• Abrasive grit: P40 for medium-coarse material removal
• Mounting type: radial mounting for spindle installation
• Construction: layered abrasive flaps for controlled wear
• Material compatibility: suitable for ferrous and non-ferrous metals and wood
• Packaging options: available in packs of 50 or 100 pieces

How to use

Install the flap disc onto a compatible spindle following the tool manufacturer’s instructions and ensure the mounting is secure. Use appropriate rotational speed limits for the disc size and maintain a steady, controlled contact angle when working on the material. Apply light to moderate pressure; excessive force can reduce flap life and change the finish quality. Always inspect discs for damage before use and replace if any flaps are torn or the mounting is compromised.

Usage recommendations

Wear eye and hearing protection, gloves and a dust mask or respirator suitable for the generated dust and particles. Ensure the spindle and backing fittings match the disc dimensions and that the operating speed does not exceed the disc’s rated maximum. For consistent results, allow the abrasive to do the cutting—avoid aggressive side loading and periodically check work progress to prevent over-grinding.
