Abrasive spiral power brushes are made with galvanized steel wire, and come with either a single spiral or double-stem, filled with Silicon Carbide abrasive Nylon or Aluminum Oxide abrasive Nylon. These materials provide for a high degree of stiffness, a fast cutting rate, and can be used for both wet and dry applications, manually or in power tools.
Single spiral, double stem brushes use one layer of filament twisted between double stem wires for added strength. It is always important to operate a spiral brush in the same direction as the twist in the stem because rotating the brush in the opposite direction may loosen the stem wire and cause it to separate and come apart.
Brush lengths range from 1-1/2" to 2", with overall lengths ranging between 4" to 5-1/2", and brush diameters from ¼" to 2".
These durable, abrasive spiral power brushes come in a choice of abrasive Nylon fill materials where the Nylon has been impregnated with an abrasive mineral such as silicon carbide or aluminum oxide. The sides of the Nylon filament act as flexible files to reach surfaces where wire bristles might not be as effective. Silicon carbide grit is coarse and acid resistant, with a range from 80 to 320, whereas aluminum oxide is much finer having a grit of 600. Silicon carbide grit adds hardness to the Nylon filaments having a Mohs value between 9 and 10. Gritted aluminum oxide is a very popular abrasive choice being both fracture-resistant and strong.
The wire stems are made of galvanized steel. Galvanized steel has superior resistance to heat, rust and corrosion and is excellent for both wet and dry applications. Galvanized steel is coated with a thin layer of zinc that helps guard against corrosion and unwanted damage through chlorine exposure.
