DeWalt Die Grinders
Choosing a DeWALT Die Grinder
DeWALT die grinders run burrs, small wheels, and polishing bits for porting, deburring, and weld cleanup. Cordless 20V MAX options include the DCG426 variable speed die grinder, the ATOMIC DCG420 straight model, and the ATOMIC DCG422 right angle model, in tool-only and POWERSTACK kit versions. Corded choices include the DWE4997VS brushless variable speed grinder and the DW887, DW888, and DWE4887. The DWMT70783 straight and DWMT70782L angle die grinders are pneumatic.
What to Look For
- Straight or right angle. Straight grinders reach into holes and channels. Right angle grinders work flat surfaces and tight corners.
- Speed control. Variable speed models like the DCG426 and DWE4997VS let you slow down for polishing and soft metals.
- Lock-on. N models have no lock-on switch, which many shops require.
- Power source. Cordless and corded grinders work anywhere. Pneumatic grinders fit shops with compressed air.
