1.The same size buffing wheel can be used to obtain different surface speeds,as measured in surface feet per minute(SFPM).A 3" or 4" diameter buff can provide the 1,750 to 3,450 SFPM recommednded for polishing and the 3,450 and higher SFPM recommended for buffing.The chart below shows the SFPM obtained with different diameter wheels at full,medium,and low speeds.

2.The SFPM can be varied while using the same wheel.This will give better results on different types of material.

3.The 7,000 RPM maximum speed will enable you to get much higher SFPM with smaller buffs such as 1" or 2" buffs or inside ring buffs than slower single or double speed equipment.

4.The maximum speed of 7,000 RPM is also fast enough to permit the use of small mounted abrasive points,brushes,cutters or other accessories in the two collet holders CHA-1 and CHA-4,and B Flexades which are available as optional accessories.
