1. Use the largest diameter brush the job will accommodate; the brush will perform better, last longer.
2. The longer the trim length of bristles, the more flexible the brush. The shorter the bristles, the stiffer the action.
3. Choose the arbor hole diameter that fits snugly over your power tool shaft without being loose or wobbly as the brush turns.
4. Bristle wire form: Crimped wire produces more continuous brushing action easier on a surface. Straight wire provides maximum brushing action for more severe applications. Normally used in twisted-knot brushes.
