Can a Makita Impact Driver Be Used to Drill?

While it is possible to use a Makita impact driver as a drill in certain situations, it is important to note that it is not specifically designed for drilling tasks. Impact drivers can be used for drilling small holes in materials such as wood, thin metal sheets, plasterboard, and plastic. However, there are some disadvantages to using an impact driver for drilling purposes.

Disadvantages of Using a Makita Impact Driver as a Drill

Impact drivers are powerful and versatile tools designed primarily for driving screws, bolts, and nuts with ease and efficiency. However, some users may attempt to use these tools for drilling tasks, which can lead to suboptimal results and potential damage to both the impact driver.

Rotation and Concussive Force Combination: Impact on Drilling Functionality

The primary difference between an impact driver and a drill is the way they deliver force. An impact driver combines rotational force with short bursts of downward (concussive) force, which allows it to handle high-torque applications effectively. While this feature makes it excellent for driving fasteners, it can negatively affect drilling functionality in several ways:

1. Precision and accuracy: Due to the chuck wobble inherent in impact drivers, holes drilled may not be as precise and can end up larger than required. The combination of rotational and concussive forces can cause the drill bit to deviate from its intended path, resulting in inaccurately drilled holes.

2. Drilling in harder materials: Impact drivers will struggle to drill through tougher materials such as brick or concrete. The concussive force can cause the bit to bounce off the surface, leading to ineffective drilling and potential damage to the workpiece.

3. Potential tool damage: Using an impact driver for drilling tasks may also cause undue stress on the tool’s internal parts, leading to premature wear and potential tool failure.

Scenarios Where Impact Drivers Can Be Ineffective or Harmful

There are several situations where using an impact driver for drilling can be counterproductive or even damaging:

1. Drilling in masonry: As mentioned earlier, impact drivers are not well-suited for drilling through hard materials like brick or concrete. Attempting to do so may result in a poorly drilled hole and potential damage to both the tool and the workpiece.

2. Precision drilling: The inherent chuck wobble in impact drivers makes them unsuitable for tasks requiring precise and accurate holes, such as cabinetry or woodworking projects.

3. Large diameter holes: Impact drivers are not designed for drilling large diameter holes. Attempting to do so may cause excessive strain on the tool and damage the bit or the motor.

If you still need to use an impact driver for drilling, follow these guidelines to mitigate risks:

1. Use high-quality HEX drill bits specifically designed for use with impact drivers.

2. Start at a low speed and gradually increase as needed for better control and precision.

3. Apply steady pressure on the tool while drilling to ensure proper alignment and prevent deviation from the intended path.

While impact drivers are powerful and versatile tools, they are not the best choice for drilling tasks. The combination of rotational and concussive forces may lead to imprecise holes, difficulty drilling in harder materials, and potential damage to both the tool and the workpiece. Instead, it is advisable to use dedicated drilling tools like standard drills or hammer drills for optimal results.

How Do You Put a Drill Bit in a Makita Impact Driver?

To use a Makita impact driver for drilling, you will need to use HEX drill bits instead of regular drill bits. These bits can be inserted into the chuck the same way you would insert a screwdriver bit. When selecting HEX drill bits, it’s crucial to choose high-quality options. Some HEX drill bits have a drill bit attached to a HEX base, making them weaker than standard drill bits. The best HEX drill bits are those moulded from a single piece of high-quality metal.

In conclusion

While a Makita impact driver can be used for drilling in specific scenarios, it is not the optimal tool for this purpose. The limitations in precision and suitability for harder materials make it less desirable for drilling tasks compared to a dedicated drill.

If you do decide to use an impact driver for drilling, be sure to invest in high-quality HEX drill bits to ensure better performance and durability. Ultimately, if drilling is a primary requirement for your projects, it is recommended to invest in a separate drill designed specifically for this task.
