What is Bump Firing In Nail Gun – What It Is and How to Do It Safely

What is Bump FiringIf you have any nailing task at hand, you may wonder about the best nail-firing mode. And bump firing is one of the most common nail shooting techniques. In simple words, it is a process used in nail guns for driving nails in rapid succession.

However, there’s a lot more to know about what is bump firing, its advantages, disadvantages, uses, and so on. In this guide, we will explore all these things so that you can choose between bump firing and sequential firing.

Let’s take a glance!

What is Bump Firing?

Bump firing is a process of rapid driving of nails into a surface that involves pulling down the trigger and bumping the safety tip or nose of the nail gun against the object. The nail gun fires a nail when the safety nose comes into contact with the surface.

In other words, it involves pulling the trigger continuously and allows single nail firing by first activating the safety tip and then pulling the trigger. This process allows for rapid nail shooting without the need for releasing or re-engaging the trigger after every nail fire.

Advantages of Bump Firing

  • Bump firing enables a smooth nail driving experience with greater efficiency and speed
  • LHigh speed reduces nailing time and effort while also ensuring increased productivity to deal with high-end nailing applications.
  • Unlike manual hammering or traditional trigger-pulling methods, bump firing reduces hand fatigue and physical strain on the operator’s arms.
  • It also ensures a fast nail firing rate which makes it ideal for larger projects such as flooring, roofing, fencing, siding, and pallet projects.
  • Bump firing is easier to use with less skill required

Disadvantages of bump firing

  • There may be a higher risk of an unintentional discharge because the user could inadvertently bump the safety nose against an unexpected target or lose control of the gun.
  • Bump firing also carries a greater potential for nail jamming or misfiring which can lead to damage to the working object or nail gun.
  • The nail placement by bump firing is less precise since it prioritizes speed the most over precision.

What should I choose: bump firing or sequential firing

You should choose between bump firing and sequential firing depending on your project and personal preference.

In comparison to sequential firing, bump firing offers a faster firing rate and more speed. However, it can be less accurate and can cause unintentional firing. Therefore, it would be suitable for projects where speed is more vital than precision such as framing or pallet projects.

When it comes to sequential firing, it has a slower firing rate while offering increased precision and control over the projects. So, you can use this type of firing mode for delicate tasks where precision is more important than speed including finishing work, molding, or cabinetry.

Thus, you have to consider the types of tasks at hand and your particular needs before deciding between bump firing and sequential firing. If your project needs more speed, then you should choose bump firing but if it prioritizes precision and controls more, sequential firing is the best option.

Frequently Asked Questions (FAQs)

Q: Is it safe to do bump firing with a nail gun?

If you’re well-known with the process, you can successfully do bump firing with a nail gun. However, you have to take proper safety measures such as wearing safety goggles, eye protection, etc. Make sure to follow the manual guide of the nail gun on bump firing techniques.

Q: Do all types of nail guns support bump firing?

No, all nail guns aren’t compatible with bump firing. Certain nail gun models, especially pneumatic or cordless nailers come with a selective actuation mechanism, to support bump firing mode. You have to examine the manufacturers’ instructions and nail gun specifications whether it has bump firing mode.

Q: What tips should I follow to ensure successful bump firing?

The following tips should be followed to ensure successful bump firing:

  • Maintain control over the nail gun
  • Keep the nail gun directed away from unintentional firing
  • Be careful about the risk of nail jamming or misfiring


After reading this article on what is bump firing, we hope now you’re clear that bump firing is a technique used by professionals and DIY enthusiasts to rapidly drive nails into a surface.

To conclude that, in addition to saving time and ensuring greater output, bump firing can also cause some safety issues like accidental firing or misfiring. Therefore, you should take proper safety measures like wearing safety googles, eye protection, etc. when using bump firing.
