Putty discs Hermes K.DISC 225 PS33BK Ø225 mm grit 180, 50 pcs

Hermes K.DISC 225 PS33BK putty/finishing sanding discs are 225 mm diameter abrasives with grit 180, supplied in a pack of 50. They are designed specifically for sanding putty, filler and fine surface preparation on wood, composites and painted surfaces. The discs feature a PS33BK backing pattern that ensures secure attachment to compatible sanding plates and to pneumatic or electric random orbital sanders. Their 180 grit provides a balance between material removal and surface finish, making them suitable for final shaping and smoothing before painting or further finishing.

Advantages

The discs combine a consistent abrasive grit with a backing that offers reliable grip on sanding pads, reducing slippage during use. Their 225 mm diameter covers a large sanding area to speed up work on bigger panels while maintaining control for detail areas. Packaged in a set of 50, the discs provide cost-effective replacement options for repeated sanding tasks and reduce downtime for changing abrasives.

How to use

Attach a Hermes K.DISC 225 PS33BK disc to a matching 225 mm sanding pad or backing plate on a pneumatic or electric sander, ensuring the PS33BK pattern aligns for secure fit. Start sanding using light to moderate pressure and keep the tool moving to avoid gouging or overheating the surface. Check the surface frequently and replace the disc when the abrasive performance decreases or the backing shows wear. Use appropriate personal protective equipment such as dust masks and eye protection when sanding putty or painted surfaces.

Usage recommendations

For best results on automotive panels, begin with a coarser grit if significant material removal is needed, then finish with the 180-grit Hermes K.DISC to achieve a smooth surface ready for priming or painting. Maintain a steady, even motion and replace discs in the pack as they clog or wear to preserve consistent finish quality.
