§ FAQ

What makes the DCG420XB an 'extended' die grinder?

The DCG420XB features a longer, slimmer neck with an overall length of 17.83 in., allowing it to reach deep inside pipes, cavities, and confined mechanical assemblies that a standard inline die grinder cannot access.

How much slimmer is the DCG420XB neck compared to a standard die grinder?

DEWALT states the DCG420XB neck is 35% slimmer than a standard die grinder, providing improved ergonomics and clearance for work in narrow openings.

Does the DCG420XB come with a battery?

No. The DCG420XB is a tool-only model. It is compatible with all DEWALT 20V MAX* and ATOMIC 20V MAX batteries, sold separately.

What type of accessories fit the DCG420XB?

The DCG420XB accepts standard 1/4-in. shank die grinder accessories including carbide burrs, mounted grinding points, and deburring tools.

Does the DCG420XB have anti-kickback protection?

Yes. The DCG420XB includes DEWALT's ANTI-ROTATION System that detects bind-up and stops the collet to reduce reactionary torque during operation.
