The DeWalt D26450 random orbit sander has a 3.0 Amp motor which deliver 12000 OPM. The D26450 random orbit sander features the Controlled Finishing System (CFS), exclusive to DeWalt. CFS mechanically controls pad speed and minimizes material gouging that can occur during start up. The random orbit sander offer a 3/32 orbit diameter that provides an optimal pad swath for the progressive removal of material. To increase durability, it features a designed motor, dust sealed switch to prevent contamination as well as 100% sealed ball bearing construction. In addition to the rubber grip, the sander is also equipped with a dual-plane counter-balanced fan that mechanically reduces vibration further and in turn, decreases the likelihood of operator fatigue.
