Sanding

 

Sanding with angle grinders sometimes referred to as linishing differs to grinding only in that finer grit sizes are often used to remove excess material. P40, P60 with finer grit sizes, P80, P100 and P120 employed to create improved surface finishes.

 

  • Fibre backed sanding discs consist of a single layer of abrasive bonded to a fibre backing. (These require a suitable backing pad often made of a rubber compound with a metal core. The fibre disc is secured to the backing pad by a retaining nut that screws on to the spindle of the grinder.). The fibre disc offers greater flexibility, especially on contours, over flap discs.  It has the advantage of sanding most metals, stone based materials and wood. Discs are available in 100mm, 115mm, 125mm and 180mm diameter. As with grinding discs aluminium oxide abrasive is used on most steels and silicon carbide on stone based materials with both being able to be used on wood. Zirconia is a cool cutting abrasive ideal for use on stainless steel as well as wood. Long-lasting, cool cutting and aggressive with a faster cutting rate ceramic abrasive is ideal for most metal sanding. If you find it difficult to get into small areas consider using smaller fibre discs that can be used with a die grinder or drill and a quick release mechanism. Available in 50mm and 75mm sizes.

  • Semi-flexible sanding discs.  Sanding of stone based products. These are available in 115mm, 125mm and 180mm diameter. Silicon carbide abrasive is bonded on to a heavy duty fibre backing. Use for sanding stone based materials including marble, granite, concrete, cast iron and fibre glass. Requires a suitable backing pad.

  • Flap discs. Sanding of most metals. These are available in 100mm, 115mm and 125mm diameter. Aluminium oxide abrasive is used for mild steel sanding whilst the more popular zirconia aluminium oxide abrasive is designed for sanding stainless steel (INOX). Long-lasting and aggressive with a faster cutting rate ceramic abrasive is ideal for most metal sanding applications.

  • Surface blending discs. These were originally developed for use in surface preparation but are increasingly used where sanding discs may have been used in the past. They have the advantage of having an extremely open structure. This allows dissipation of heat and dust avoiding the clogging that may be associated with single layer abrasive discs. They are also capable of removing significant amounts of material but by easing on the pressure can create a superior surface finish. Surface blending discs allow greater control and less downtime by reducing the need to change worn or degraded discs. These discs are available in silicon carbide abrasive or the longer lasting ceramic abrasive. Available in 115mm, 125mm and 178mm diameters.
