Product Description

?

This is an authentic manufacturer-sourced replacement part which is specially designed for use with DeWALT drills. It allows a user to secure drill bits. This 1/2" capacity chuck uses a 1/2"-20 spindle for mounting to the drill. The light-weight plastic and single-sleeve design provide user comfort while improving efficiency with easier keyless bit changes. The ratcheting action clicks the jaws tightly into place for reduced bit slippage. Keep in mind this high-quality component is sold individually. Due to a replacement some models may require #50 Part Number N016823. Please make sure to refer to the owners manual for the correct installation. See our post on <a href="http://forums.ereplacementparts.com/power-tool-repair/8-removing-cordless-drill-chuck.html" target=blank_<u>Removing a Cordless Drill Chuck</a> if you need help replacing your old chuck.

I removed the LH threaded chuck screw with a torx bit. Placed the short end of the largest allen wrench I could fit into the chuck and tightened the chuck. Put the drill in low speed and in the drill mode. Laid the drill on its side and hit the allen wrench with a mallet to remove it from the spindle. Removed the chuck from the spindle ,t hen threaded the new chuck on, then screwed the new chuck screw in, to hold the chuck on.

I used a Torx T-20 screwdriver to remove the LH chuck screw. I then made sure that the drill was in low gear and in the drill setting. Use the largest allen wrench that you can tighten in the chuck. Insert the short end of the allen wrench into the chuck and tighten up the chuck. Lay the drill on its side , then strike the long end of the allen wrench with a hammer to unscrew it from the spindle. Once the chuck is removed, screw the new chuck on the drill spindle tight. Then screw in the LH chuck screw. And you\'re done!

Had to provide a washer (spacer) between the chuck and the drill. Original chuck was constructed with a lip (for lack of a better word) to keep it from binding on the drill housing.
