DeWalt DCM848N-XJ 18V politriz excêntrica a bateria, 125 mm

The DeWALT DCM848N-XJ is an 18V cordless disc sander with a brushless motor, designed for portable sanding and polishing tasks. It offers an idle speed range from 2000 to 5500 RPM and features a hook-and-loop backing pad for quick polishing pad changes. With a compact form factor and a weight of 2.5 kg, the tool is intended for use in both professional and DIY environments where controlled, continuous sanding is required.

Advantages

The brushless motor delivers improved performance and longer motor life under demanding applications. Variable speed control is provided both by a dial for setting a target RPM and by a variable trigger that fine-tunes speed according to the force applied. A lock-on trigger enables continuous operation without user fatigue, while an ergonomic gearcase grip increases control and comfort during extended use. The hook-and-loop backing pad simplifies replacement of polishing pads.

Suitable for

• Sanding and polishing wood surfaces
• Removing paint or varnish from flat panels
