Silverline 75mm x 533mm 40 Grit Sanding Belts – Key FAQs

• What is 40g best used for on a belt sander?
  40g is very coarse and ideal for fast stripping and heavy stock removal, such as removing old coatings or levelling rough timber before moving to finer grits.

• Will these belts fit my belt sander?
  They are designed for any electric belt sander that uses 75mm x 533mm belts. Check your current belt size or tool manual to confirm compatibility.

• What does X-weight cloth backing mean?
  X-weight cloth is a strong backing material that improves tear resistance and durability, helping belts cope with pressure and edge work.

• What is the benefit of a semi open coat belt?
  Semi open coat leaves more space between abrasive grains to help reduce loading, which can improve performance and belt life when sanding dusty materials.

• Can these belts be used on paint and varnish?
  Yes. 40 grit is effective for stripping paint and varnish, but it leaves a heavier scratch pattern—follow up with 60/80/120 grit to refine the surface.

• How can I make sanding belts last longer?
  Use light pressure, keep the belt moving, and clean it when it loads up. A belt cleaning block can remove clogged debris quickly and help restore cutting action.

You can extend the life of your discs by using a sanding disc and belt cleaning block this removes clogging simply and efficiently.
