Filaments are compressed and inserted into pre-drilled holes under pressure and retained by steel staples driven into the core.
As above, filaments are cemented into pre-drilled holes in the core using epoxy resin. This method makes a secure, sterilizable brush that can be done without staples. Unstapled epoxy-set brushes are hand work and expensive.
Also known as Drawn-In-Wire – brushes are assembled by sewing filaments into pre-drilled holes with fine wire through the core where it is tied. This is a very secure method of holding material into the brush and it is labor intensive.
Most common shape used unless there are specific reasons for using other shapes.
To fit the filament to the surface being worked upon.
To conform to the surface being brushed.
For brushing irregular or uneven surfaces. Many variations are possible.
Combination of step trims to conform to the surface being brushed.
|Double Bevel, Chisel or Converging:
To conform to the surface being brushed, or for greater concentration of brush filaments to obtain more intense brushing action.
