To prevent this kind of damage, the best technique is to stop just short of driving the nail completely, then use a nail set to finish the job. This small, inexpensive accessory extends your reach with the hammer, letting you strike just the nail—not the wood trim.
Nail Set vs. Power Brad Nailer
A collection of nail sets was once standard equipment in any carpentry toolbox, but owning a power brad nailer now eliminates the need for a nail set in many instances. Powered by a burst of air pressure, power brad nailers drive small finish nails (brads) so they are automatically countersunk below the surface of the workpiece, eliminating the need for setting the nails by hand. Power brad nailers are available in several types, included small corded electric nailers, battery-powered nailers, and pneumatic nailers that require an air compressor. Once used mostly by pros, a battery-powered brad nailer is now quite affordable and practical for homeowners. A nail set is a good addition to your toolbox, even if you own a brad nailer. Oftentimes a nail gun will not set the nail head below the surface for various reasons, and a nail set helps in that case.
Safety Considerations
A nail set is not usually regarded as a dangerous tool, but makers of hammers and other striking tools always advise users to wear eye protection when pounding nails or striking tools, such as chisels and nail sets. There is a small but real chance the tool could shatter, sending sharp shards toward your eyes. Hearing protection is also a good idea during any metal-on-metal hammering. Wear a glove on the hand that is holding the nail set. If you do happen to accidentally strike your hand, the glove will soften the blow.
How to Use a Nail Set
Keeping a Nail Set Clean
Wipe the nail set clean after each use. If the tool develops rust during storage, you can clean it with light machine oil applied with a scouring pad, then wipe the tool dry using a clean rag. While not necessary, you may also find it helpful to switch to a hammer with a milled or checkered face for better contact between the hammerhead and the nail set.
When to Replace a Nail Set
Replace a nail set if the pointed end loses its round shape from repeated use, or if the striking head develops a chip or crack.
