Grit: 120
Diameter: 40mm
Shaft: 6mm
Width: 20mm

This rotary flap wheel, measuring 40mm in diameter with a 20mm width and a 6mm steel shaft, is designed for precise surface finishing and blending tasks. Its 120 grit abrasive offers a finer touch, making it excellent for achieving smooth, polished surfaces on various materials like metal, wood, and plastic after initial shaping or coarser abrasion. The overlapping flap construction ensures consistent contact and even wear, continuously exposing fresh abrasive for a uniform finish without gouging or damaging the workpiece. Ideal for detail work, final finishing stages, and preparing surfaces for coatings, this flap wheel is a valuable tool for achieving high-quality results with drills or die grinders.
The 120 grit offers a good balance between material removal (though less aggressive than coarser grits) and the ability to create a smooth surface. The flexible flaps ensure consistent contact with the workpiece, preventing deep scratches and providing a uniform finish over contoured or irregular surfaces.
Application:
- Fine Metal Finishing
- Woodworking
- Plastics Finishing
- Automotive Detailing
- DIY
What is grit?
When talking about sandpaper 'grit' is a reference to the number of abrasive particles per inch of
sandpaper. The lower the grit the rougher the sandpaper and conversely, the higher the grit number the smoother the
sandpaper.
This make sense if you imagine how small the particles on an 1000-grit sandpaper would need to be to fit into a 1' square (25,4mm square). Sandpaper is referred to by the size of its grit (Example 120-grit sandpaper or P120 sandpaper).
Choice
You need to choose the grit size of sandpaper depending on the particular job you are trying to accomplish. For heavy sanding and stripping, you need coarse sandpaper measuring 40- to 60-grit; for smoothing surfaces and removing small imperfections, choose 80- to 120-grit sandpaper. For finishing surfaces smoothly, use a super fine sandpaper with 360- to 600-grit. Many jobs require you to “go through the grits.” This means you start the project using lower-grade grit and use finer pieces of sandpaper as you progress. Each time you advance to a higher grit sandpaper, you remove the scratches from the previous layer.
