Why does the 300 Series have high speeds?
The 300 Series rotary tool has high speeds of 5,000 – 35,000 rpm. High speed, when coupled with the right accessory, is what makes the rotary tool so useful. The best results generally happen when taking a less aggressive, more frequent pass. Too much pressure on the spinning accessory and the work piece can damage the accessory and the work piece. If the accessory is not producing the desired result, we would recommend adjusting the speed, or trying an alternative accessory.
