Die Grinder Vibration Reduction

High-speed bits were used to trim aluminium panels, but the tool speed was far too low. Changing the die grinder for a high speed unit to match the bit left the vibration unchanged, but the improved efficiency cut working time from 20 minutes to 2 minutes, reducing the risk by a factor of three. On a similar operation, simply ensuring the grinding bit was pushed fully into the chuck reduced the level of vibration by a factor of x4.
