Description
50 x 20mm 120 Grit Flap Wheel
Aluminium Oxide.
Flap wheels are ideal for stock removal, deburring, cleaning, blending and finishing in a variety of applications, including stainless steel pipe fabrication and stainless steel vessels.
A flap wheel is an abrasive wheel made from abrasive strips (flaps) radiating from a centre hub.
Bordo flap wheels come in many different diameters, widths and grits.
The outside diameter of the wheel can range from 30mm to 80mm.
Bordo flap wheels use Aluminium Oxide (Al2O3) as the abrasive material which is bonded to the strips of the wheel.
Aluminium oxide is a fused, hard synthetic crystalline abrasive.
Within the abrasive compound the Aluminium and Oxygen elements are held very close together causing these two relatively light elements to make a hard, dense crystal.
On the MOHS scale of hardness Aluminium Oxide is 9.0.
This hard crystal structure has a tendency to slowly dull or round and is hard to fracture.
