§ FAQ

What is the Lanyard Ready™ Attachment Point on the DCG400BLR?

The Lanyard Ready™ Attachment Point is a built-in anchor point that allows users to clip a tool lanyard to the grinder. This prevents the tool from falling when working at height. The lanyard is sold separately.

Is the DCG400BLR the same grinder as the DCG400B?

Yes, the DCG400BLR uses the same brushless motor and 4-in. disc as the DCG400B. The only addition is the Lanyard Ready™ Attachment Point, which slightly increases the assembled weight to 4.45 lbs.

What battery does the DCG400BLR use?

The DCG400BLR is compatible with all DEWALT 20V MAX* batteries. It is sold as a bare tool without a battery or charger.

Does the DCG400BLR have anti-kickback protection?

Yes. The DCG400BLR includes DEWALT's ANTI-ROTATION System, which stops the wheel when a pinch, stall, or bind-up event is detected, reducing reactionary torque.

When should I choose the DCG400BLR over the DCG400B?

Choose the DCG400BLR for elevated work environments such as scaffolding, elevated platforms, or overhead grinding where a dropped tool poses a safety hazard. The DCG400B is sufficient for ground-level use.

What disc size does the DCG400BLR accept?

The DCG400BLR uses 4-in. grinding and cutting wheels, the same as the DCG400B. This compact disc size enables access to tight spaces inaccessible to standard 4.5-in. grinders.
