Bosch 2 608 900 039 rotary tool grinding/sanding supply Wood Sanding sheet

The Bosch EXPERT Sanding Finger is a narrow, pointed sanding blade designed to reach and sand tight gaps in decking, window shutters, staircases and other confined wood areas. It features high-quality carbide grit for effective abrasion and is available in different grit sizes: RT4 (coarse, grit 40) for rapid material removal such as paint, and RT10 (fine, grit 100) for preparing clean wood surfaces. The sanding finger is compatible with Bosch rotary tools and intended for precision sanding where standard abrasives cannot access.

Advantages

The thin, pointed design allows access to narrow joints and crevices without damaging surrounding surfaces. High-quality carbide grit provides long life and resists clogging, while the coarse RT4 version removes material quickly and the finer RT10 delivers a smoother finish. The product’s dimensions (approx. 99 mm depth and 32 mm width) make it suitable for detailed work on wood components.

Suitable for

• Sanding tight gaps in decking and floorboards
• Cleaning and preparing window shutters and frames
• Restoring old staircases and narrow wood molds
• Removing paint and surface coatings in confined areas (RT4, grit 40)
• Fine sanding and surface preparation on clean wood (RT10, grit 100)

How to use

Fit the sanding finger to a compatible Bosch rotary tool according to the tool manufacturer’s instructions. Select the appropriate grit for the task (RT4 for fast paint removal, RT10 for fine wood finishing). Gently insert the pointed blade into the gap or crevice, apply light, consistent pressure and move along the area to be sanded. Keep the tool steady and avoid excessive force to prevent damaging the surrounding surface. Clean or replace the sanding finger when abrasive performance decreases.

Recommendations

Use personal protective equipment such as safety glasses and a dust mask when sanding. Test the chosen grit on a small, inconspicuous area first to confirm the result. Replace the sanding finger when wear reduces effectiveness, and store in a dry place to maintain abrasive quality.
