DEWALT 20V MAX DCD778C2 Hammer Drill: Compact Power and Everyday Versatility
The brushless motor of the DCD778C2 provides efficient performance and longer runtime per charge. The 1/2-inch ratcheting chuck grips bits securely, while the variable speed trigger gives you the control needed for delicate surfaces. An LED light automatically illuminates dim work areas, so you can see where you're driving that final screw.
DCD778C2 Hammer Not Working? Start with These Checks
If hammer mode isn't engaging, make sure the mode collar is fully rotated to the hammer position. The hammer action only works when the drill is rotating under load, so try it against the material you're drilling. If the chuck wobbles or slips, clean the jaws and ensure the chuck is tightened; if the chuck is worn, it may need replacement.
Replacing the Chuck on the DCD778C2
To replace a keyless chuck, remove the battery, open the chuck jaws, and remove the screw inside the chuck. Insert a hex key into the jaws and tap it to break the taper loose, then unscrew the old chuck. Thread the new chuck on and tighten the screw. For the correct replacement chuck, contact Workbench World support.
Two-Battery Kit Keeps You Working
The DCD778C2 kit ships with two 20V MAX batteries, so you can charge one and use the other. The included charger and tool bag complete the package.
