I bought a DeWALT adjustable depth screw setter. How do I remove the driver, the Phillips bit tip itself, and replace it with another size bit?

grip it with a good pair of pliers or vise grips and PULL. it will come out

Dewalt list the obvious causes below.
Remember that the gun may not facilitate the use on specific materials that are just too much for the gun to handle. The most common cause for this issue is depth adjustment is not set properly. Also make sure that the nails being used are the correct nails for the gun. Its possible to buy the wrong type and they look very similar to the ones needed.

Here is The website addy for Dewalts pdf user manual and tech tips.

Low battery charge or damaged battery Charge or replace battery
Depth adjustment set too shallow Rotate depth adjustment wheel to a deeper setting
Tool not firmly applied to workpiece See instruction manual
Material and fastener length Choose appropriate material or fastener length
too rigorous an application
Damaged or worn driver blade tip Replace driver/return assembly; see authorized service center
Damaged or worn driver/return assembly

First you put in a screw bit then select the screws that suit your job at hand. Now set your first screw,if it is to deep turn the collar to the left, if it is not deep enough turn the collar to the right.

should be able to unscrew and remove plastic head, and pull out bit by hand

Below find information on how to adjust for depth, however if you have already made adjustment then check for broken tip on driver blade. The blade is not expensive and available from dewalt service center.

Please note the following from manual:

Adjusting Depth
The depth that the fastener is driven can be adjusted using
the depth adjustment wheel (C) on the side of the tool.
WARNING: To reduce risk of serious injury from
accidental actuation when attempting to adjust depth,
ALWAYS:
• Remove battery pack.
• Engage contact trip lock-off.
• Avoid contact with trigger during adjustments.
1. To drive the nail shallower, rotate the depth adjustment
wheel (C). There are twelve depth settings, 1 being the
shallowest and 6 being the deepest.
2. To sink a nail deeper, rotate the depth adjustment
wheel (C) to a higher setting.

Drill a hole in the top of the phillips head screw with a 3/16 th's bit. Don't drill the head of the screw off, just drill deep enough for a torx bit to hold. Take a T-30 torx bit and tap in into the hole you have drilled. Then turn the screw clockwise and it should come out fairly easily.

It's not the tip, but the screw gun itself. The screw gun has a clutch on it that allows you to set the screw at different depths. You must adjust the screw gun to the desired depth. The deeper you want the screw to go, the less the clutch will slip.

you should just have to turn the collar, it is marked with which way to turn for deeper setting of the screws. You can go to Dewaltservicenet.com with your model number and download a copy of the owners manual for more specific information.

hello. thanks for choosing fixya. you adjust with 8mm socket or adjustable wrench. just turn the shaft as you hold onto the brass piece. make the phillips head as deep or shallow as you choose for your application.

A TORX I believe , if it is a 6 point star type screw hole? They are measured in mm I think and 15 and 20 are the most common sizes.
