Overview:

The Silverline Sander Sanding Belts (100mm x 610mm) 120 Grit 846448 are ideal for smoothing and fine preparation work on larger surfaces using compatible electric belt sanders. Manufactured from flexible aluminium oxide abrasive fully resin bonded to tough GX51 backing cloth, these belts deliver consistent cutting performance with excellent durability for workshop and site use. The fine 120 grit grade is perfect for refining timber after coarse sanding, preparing painted surfaces for recoating, and achieving a cleaner finish before applying paint, stain or varnish. Belt sanding spreads wear evenly around the loop, which helps belts last longer than flat sheets on bigger jobs. Supplied in a practical pack of 5 and sized to fit all 100mm x 610mm belt sanders.

Silverline 100mm x 610mm 120g Sanding Belts – Key FAQs

• What is 120 grit best used for on a belt sander?
  120 grit is ideal for smoothing and preparation before finishing—refining the surface after coarser sanding and getting timber or painted areas ready for paint, stain or varnish.

• Will these belts fit my belt sander?
  They’re designed to fit any electric belt sander that uses 100mm x 610mm belts. Check your existing belt size or tool manual to confirm compatibility.

• What is the benefit of GX51 backing cloth?
  GX51 cloth backing is tough and durable, improving tear resistance and helping the belt cope with pressure and longer sanding sessions.

• Why does belt sanding often last longer than flat sandpaper?
  Belts spread wear evenly around the loop as they run, which can improve durability compared to flat sheets on larger sanding tasks.

• How can I extend belt life?
  Use light pressure, keep the sander moving, and clean belts when they load up. A belt cleaning block helps remove clogging and restores cutting action.

• What grit should I use before 120 grit?
  Typically use 60 or 80 grit first for heavier removal and shaping, then switch to 120 grit to smooth and prepare the surface for finishing.

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