A nail puller is a tool used to extract nails from wood. Different types are available, including the bar nail puller, moulder bar, and wrecking bar. Pneumatic nail pullers are also available. When choosing a nail puller, consider the material and type of nails being used. Construction workers may keep a selection of nail pullers on hand.
A nail puller is a handy time-saving device used to extract nails that are bent, driven in the wrong place, or need to be pulled out of a piece of wood for other reasons. Once a nail has been driven into a piece of wood, it is impossible to pull it out by hand. The nail puller solves this problem. One end is wedged under the nail head while the user applies pressure to the other end. After applying enough pressure, the nail is pushed out of the wood and a new nail can be driven in if necessary.
Various types are available. The simplest type is the bar nail puller. Typically resembling a small crowbar, one end of the bar is V-shaped and slightly angled to leverage the nail with little damage to the wood. Some types are designed to trim the edge of the nail so that the remaining piece is even with the wood instead of pulling the nail all the way out.
The moulder bar is a specific type created to work with moulding, a delicate material that scratches easily. This bar can pull nails out with little damage to the molding. The wrecking bar, also known as a jerk bar, is a second type of nail puller designed for heavier projects that require more force to remove the nail. Other rod nail extractors are made in different lengths and for different materials, but the basic concept behind how they work is the same.
Pneumatic nail pullers are the second type available. Less common and more expensive, the pneumatic nail puller uses air pressure to pull the nail out. This type means less work for the user and claims to work faster than the traditional human-operated nail puller. The pneumatic nail puller digs into the wood and locks around the nail before using air pressure to pull it out of the wood.
When choosing the right nail puller for a project, consider how delicate the material is and what type of nails are being used. A construction worker might consider keeping a basic general purpose breaker bar and a selection of bar nail pullers made for certain types of nails or wood on hand in his toolbox in case they are needed. He might consider investing in a pneumatic version if the need to pull nails is a common occurrence on the job.
