Straight Hand Tool Series

1/4” / 6mm Capacity

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

Optional dead man’s trigger switch for quick-shut off available with the 525DM.
