How to Drill Open a Gun Safe in 3 Simple Steps
To drill open your gun safe, first find a thinner steel spot—usually on the back or bottom—avoiding hinges and locking parts. This is key to making the drilling process easier and more effective.
Next, pick cobalt or HSS drill bits, starting with a small pilot hole and using cutting oil to keep bits cool. These tools help you penetrate the metal without damaging your drill bits.
Finally, wear safety gear, drill slowly with steady pressure, and stop if you feel resistance or see damage.
If you want to master these steps and handle any challenges confidently, keep going.
Key Takeaways
- Identify thinner steel areas on the safe’s back or bottom to drill safely without damaging internal mechanisms.
- Use a small pilot hole with a cobalt or HSS drill bit to guide larger bits and reduce heat buildup.
- Apply cutting oil regularly to prevent overheating and prolong drill bit life during drilling.
- Drill slowly with steady pressure, avoiding hinges, locking parts, and fireproofing layers inside the safe.
- Wear safety goggles and gloves, and work in a well-lit, stable environment for protection and precision.
Find the Best Spot to Drill Your Gun Safe

When you’re ready to drill open your gun safe, start by finding the best spot—usually on the back or bottom where the steel is thinner and easier to penetrate. Avoid the safe door hinges and locking mechanism to prevent damaging internal parts. Use a flashlight to inspect for any pre-existing holes or access points that could make it easier to drill a hole.
Once you spot the ideal location, mark it carefully with a marker or punch to ensure precision. Choose a drilling angle that minimizes risk to internal fireproofing materials, so you don’t cause unnecessary damage inside. By picking the right spot, you’ll make the process smoother and protect the safe’s essential components during drilling.
Choose Drill Bits and Tools for Your Gun Safe

Although drilling into a gun safe requires strength and precision, choosing the right drill bits and tools will make the job much easier. You’ll want cobalt or high-speed steel (HSS) drill bits because they can penetrate the hardened steel layers in the safe.
Start with a small pilot hole—around 1/8 inch—to guide your larger drill bit, which should be slightly bigger than the opening you need, typically 1/4 to 3/8 inch. Using cutting oil on the drill bits helps reduce heat and prolong their life.
Since gun safes often include sheet metal layers, a drill with variable speed settings gives you better control and prevents damage. Picking the right tools upfront saves time and effort during drilling.
Drill Safely and Handle Common Drilling Challenges

Since drilling into a gun safe involves tough materials and potential hazards, you need to work carefully and methodically. Choose the right type of drill—preferably one compatible with cobalt or high-speed steel bits—to avoid damage to the safe. Start with a small pilot hole to reduce heat buildup, and apply cutting oil regularly to keep the bit cool and extend its life.
Drill slowly, using steady pressure to prevent warping or cracking, especially through thick steel layers. Identify the safest drilling point, like the back or bottom of the safe, to minimize difficulty. Always wear safety goggles and gloves to protect yourself from metal shards.
