How to Remove the Drill Chuck on a DeWalt XRP

Updated February 21, 2017

DeWalt XRP drills are one of the more popular cordless drills. To service the drill, it is sometimes necessary to remove the chuck. The chuck is the cylindrical protrusion at the tip of the drill. The chuck has three "fingers" that move in unison to grasp the drill bit, while keeping the bit centred. XRP drills feature a keyless chuck that allows bit changes without the use of tools. To open the chuck, turn the front counterclockwise; to tighten the chuck, turn the front clockwise.

Lock the drill by setting the reversing switch to its centre "Off" position or removing the battery.

Set the clutch to "Drill" position. Set the gearshift to its lowest range.

Insert the short end of a hex key into the chuck and tighten the chuck firmly.

Hold the drill firmly on the edge of a table or lock it in a vice with the free end of the hex key pointing to the right. Strike the end of the hex key with a dead-blow hammer or soft-faced mallet, turning the chuck in a clockwise direction.

Open the chuck fully to remove the hex key and expose the head of the retaining screw inside the chuck. Turn the screw clockwise (the screw has a left-hand thread) using a Torx driver. Remove the screw completely.

Replace the hex key in the chuck and tighten. Point the free end of the hex key to the left, and strike the free end of the hex key with the hammer, causing the chuck to turn counterclockwise. You can now unscrew the chuck by turning it counterclockwise by hand.

Tip

If the existing chuck is damaged to the point that it will not tighten on the hex key, try using a pipe wrench to turn the chuck. Older drills may use a Phillips screw in place of a Torx screw.

Warning

Wear eye protection when using striking tools.
