Using the DeWalt DWPVTHLD Bit Tip Holder is quite easy. First, select whether you want to use it in straight or pivot mode. If you need to work in a tight space, switch to the 20 - degree pivot mode. Insert the holder into your cordless impact tool, drywall gun, or standard drill/driver. Make sure the tool's torque is within 2000'/lbs. When driving, use the locking collar to set the driving angle as you need. As for maintenance, after each use, wipe the holder clean with a dry cloth. Store it in a dry place to prevent rust. Check the hex shank and bit tip holder regularly for any signs of wear and tear. If you notice any issues, it might be time to replace the holder.
