Overview:

The Silverline 40 grit Random Orbit Sander 150mm Sanding Discs 301191 are designed for aggressive sanding and rapid material removal on larger surfaces. Made with aluminium oxide abrasive, these coarse 40 grit discs are ideal for stripping coatings, levelling rough timber and tackling heavy preparation work before moving on to finer grits. Each disc is pre-punched with an 8-hole pattern to support dust extraction on compatible sanders, while still being usable on pads without extraction holes. Supplied in a pack of 10, they’re a practical choice for workshop and site sanding where speed and efficiency matter. You can extend the life of your discs by using a sanding disc cleaning block this removes clogging simply and efficiently.

Silverline 150mm 40 Grit Sanding Discs – Key FAQs

• What is 40 grit best used for on a random orbit sander?
  40 grit is a coarse abrasive used for rapid material removal—ideal for stripping coatings, levelling rough timber and heavy preparation before moving to finer grits.

• Will these discs work with dust extraction?
  Yes. They’re pre-punched with an 8-hole pattern to suit many random orbit sanders with extraction. Align the holes with your pad for best airflow.

• Can I use these discs on a pad with no holes?
  Yes. You can still use them on pads without extraction holes, although dust control and disc life may be improved when extraction is used.

• How do I make sanding discs last longer?
  Use light pressure, keep dust extraction running where possible, and clean discs as they load up. A sanding disc cleaning block can help remove clogging quickly.

• What grit should I use after 40 grit?
  Typically move to 60 or 80 grit to remove the heavy scratch pattern, then step up to 120 and beyond depending on the finish required.

• Is aluminium oxide suitable for wood and paint?
  Yes. Aluminium oxide is a versatile abrasive that performs well on wood and many coatings, making it a solid choice for general preparation work.
