Brad Nailer

Brad Nailer

This is a power tool that shoots very thin nails into wood using compressed air or a battery. You use it to attach delicate trim pieces like baseboards and window casings without splitting the wood. The tiny nail heads sink into the wood so you can easily hide them with a dab of putty.

Origin

The word brad comes from the Old Norse word broddr, meaning a spike or shaft. Tool companies invented pneumatic brad nailers in the 20th century to speed up finish carpentry work.

How you'll see it used

  • A carpenter's quote for installing new baseboards includes a small line item for 18 gauge brad nails and wood putty.
  • You rent a cordless brad nailer from the local hardware store to reattach a piece of window casing that pulled away from the wall.
  • During a bathroom remodel, your contractor uses a pneumatic brad nailer to quickly install decorative shiplap planks over the drywall.

What Is a Brad Nailer?

A brad nailer is a handy power tool that shoots very thin nails into wood. You can find models that run on an air compressor or use rechargeable batteries. These tools specifically use 18 gauge nails. These nails are much thinner than standard construction nails. The word brad comes from the Old Norse word broddr, which means a spike or shaft. Tool companies invented pneumatic brad nailers in the 20th century to speed up finish carpentry work. Today, they are a staple in home workshops across the country. The thin nails have tiny heads that sink slightly below the surface of the wood. You can easily hide the tiny holes with a quick dab of wood putty. Once you paint over the putty, the nail completely disappears.

Why It Matters for Your Home

If you want to update your home, a brad nailer makes the job much easier. You use it to attach delicate trim pieces like baseboards, crown molding, and window casings. Driving nails by hand with a heavy hammer often splits thin or delicate wood. A brad nailer shoots the nail so fast that the wood rarely splits. This saves you money on wasted materials. It also saves you hours of frustrating work. When you swing a hammer in a tight corner, you risk denting the wall or the trim. A brad nailer lets you place the tool exactly where you want it and pull the trigger. If you are tackling a project covered in our Interior: Paint, Drywall & Trim guide, a brad nailer is often the best tool for the job.

Buying or Renting a Brad Nailer

You have two main choices when you shop for a brad nailer. Pneumatic nailers connect to an air compressor with a long rubber hose. They feel lighter in your hand and usually cost between 30 to 100 dollars. However, you also need to buy or rent an air compressor to make them work. Battery powered brad nailers are much more convenient because they don't need a bulky air hose. These cordless models cost between 120 to 300 dollars. Tool prices and rental rates vary by location and brand. If you only need the tool for one weekend, you can rent one at a local big box store for about 20 to 40 dollars a day.

What to Watch Out For

A brad nailer isn't a heavy tool. The nails are simply too thin to hold thick structural wood together. You should never use a brad nailer to build a deck, hang heavy cabinets, or frame a wall. It's strictly for lightweight trim, small furniture repairs, and crafts. Also, you must always wear safety glasses when using one. Sometimes a nail hits a hard knot in the wood and shoots out the side. Keep your free hand well away from the spot where the nail goes into the wood.

Always remove the battery or disconnect the air hose before you clear a jammed nail. A nailer can accidentally fire and cause a serious injury if it still has power.

Homeowners reach for a brad nailer for many different weekend projects. It's the perfect tool for adding decorative touches to plain rooms. Here are a few common ways you'll use this tool around your house:

  • Installing shoe molding around the bottom edge of your baseboards.
  • Putting up decorative shiplap or wainscoting in a bathroom or dining room.
  • Fixing a loose piece of door casing that keeps pulling away from the wall.
  • Building small wooden crafts or birdhouses with your family.

If you just bought a home that needs work, a brad nailer is a great early investment. You can read more about setting up your basic tool kit in Your First Week as a Homeowner.

Frequently asked

Can I use a brad nailer to fix a loose floorboard?

No, a brad nailer isn't strong enough for flooring. The thin nails will pull right out when you walk on the board. You need special flooring nails or screws to secure a loose floorboard.

What is the difference between a brad nailer and a finish nailer?

A brad nailer uses thin 18 gauge nails that leave very tiny holes. A finish nailer uses thicker 15 gauge or 16 gauge nails that hold heavier wood but leave larger holes you must fill. You use a brad nailer for small trim and a finish nailer for heavy doors and thick baseboards.

Do I need an air compressor to use a brad nailer?

It depends on the model you buy. Pneumatic brad nailers require an air compressor and a hose to work. However, you can buy cordless brad nailers that run entirely on rechargeable batteries.
