Sealed Steel Series

Despite its 25mm outside diameter, the 725MX has up to 0.40 hp to maintain your cutting tool’s high rotational speed at 40,000 or 50,000 rpm. The higher production rates you achieve with the 725MX will surprise you.

Air Turbine Motors® patented double direct drive in the 725MX does not get hot or vibrate. The air cools the sealed grease-packed bearings. The result is durability in 24/7 operation with no maintenance and no control system.

Mountable area of Ø 25mm OD by 39mm. Completely sealed with hose exhausts.
