525DM

1/4” / 6mm Straight Hand Tool Series

Revolutionary comfort and superior surface quality with high speed. Plenty of power for deburring, part cleaning, deflashing, or weld removal. Constant governed high speed does the cutting, not operator pressure. Eliminate heat, stress, and injury risk and end daily maintenance costs.

Just guide the 525DM with its low vibration and weight. The patented automatic brake option stops this tool in a few seconds.
