Ideal for sanding softwood floors (pine, fir, etc.)
This 185 mm diameter abrasive disc with 40 grit is designed for the initial stages of sanding softwood floors such as pine or fir. It is ideal for roughing, particularly for removing old, thick finishes or correcting irregularities before moving on to finer grits (60, then 100 to 120).
Aluminium oxide (corundum) abrasive
The material used is corundum, also known as aluminium oxide. It is a very common abrasive in woodworking and is particularly popular for sanding floorboards. It is characterised by its high hardness (9 on the Mohs scale), thermal and chemical stability, and high resistance to wear and corrosion.
Performance and cost-effectiveness
This Ø 185, 40-grit Corundum Disc offers a good balance between efficiency and cost. It is a cost-effective solution for frequent or large-scale sanding jobs, while maintaining a high-quality finish. Its durability makes it particularly attractive to professionals.
Self-sharpening action
Aluminium oxide has a self-sharpening property: the grains break naturally during use, exposing new cutting edges. This process maintains a constant removal rate, extends the service life of the Corundum disc Ø 185 grit 40 and ensures consistent performance across the entire surface.
For roughing before finishing
With the right grain size, this Corundum disc Ø 185 grit 40 is ideal for initial passes. It effectively removes old varnish, paint, glue residue and surface imperfections. It prepares the surface for finer finishing with a 60-grit disc, followed by a 100- or 120-grit disc, depending on the desired finish.
Versatile use
Although optimised for soft woods, this Corundum disc Ø 185 grit 40 can also be used on other surfaces such as certain hard woods, non-ferrous metals, rigid plastics and composites. It is a reliable and adaptable tool for a variety of renovation and maintenance applications.
Uniform finish and clean work
The structure of the corundum ensures uniform sanding, limiting deep marks and making it easier to achieve a smooth finish. This Ø 185, 40-grit Corundum Disc provides a clean and even base, which is essential for a high-quality end result when renovating wooden floors.
