Hammer Drill vs Impact Driver: Which One Do You Need?
If you’re a DIY enthusiast or a professional contractor, you probably have a power drill in your toolbox. But did you know that there are different types of drills that can perform different tasks? In this blog post, we’ll compare two of the most common and useful drills: the hammer drill and the impact driver. We’ll explain what they are, how they work, and when to use each one. By the end of this post, you’ll be able to choose the right tool for your next project.

What is a Hammer Drill?
A hammer drill is a power drill that can bore holes through tough surfaces like brick, concrete, and stone. It looks and acts like a traditional power drill, with a standard chuck, trigger, and speed control. But it has an additional feature: a hammer-like action that strikes the drill bit as it rotates. This creates a powerful impact that helps the bit penetrate the hard material.
There are two types of hammer drills: cam-action and electro-pneumatic. Cam-action hammer drills use a gear-driven mechanism that creates a back-and-forth motion of the chuck. Electro-pneumatic hammer drills use an electric motor that generates air pressure to create a piston-like motion of the chuck. Both types can produce thousands of blows per minute (BPM) to drive the bit forward.
Hammer drills are ideal for drilling holes in masonry for anchors, screws, or bolts. They can also be used for mixing mortar, chiseling tiles, or breaking up concrete. However, they are not very effective for drilling wood, plastic, or metal. For those materials, you need to switch off the hammer mode and use the drill as a normal power drill.
One of the best hammer drills on the market today is the DEWALT DCD996B 20V MAX XR Hammer Drill. It features a brushless motor that delivers up to 75% more runtime than brushed models, a 3-speed transmission that allows you to adjust the speed and torque for different applications, and an LED light that illuminates your work area. It also has a 1/2-inch ratcheting metal chuck that accepts a variety of bits and provides superior bit retention.

What is an Impact Driver?
An impact driver is a power tool that can drive fasteners like screws and lag bolts into various materials. It looks and acts like a cordless screwdriver, with a quick-change hex-shank chuck, trigger, and speed control. But it has an additional feature: a rotational impact mechanism that delivers extra torque to the bit as it spins.
An impact driver has an internal spring that compresses and releases every half turn of the chuck. This creates a sudden burst of force that increases the rotational speed and power of the bit. This helps the bit overcome resistance and drive the fastener deeper and faster.
Impact drivers are ideal for driving long and large screws into wood, metal, or plastic. They can also be used for removing stuck or rusted screws or bolts. However, they are not very good for drilling holes or driving delicate fasteners. For those tasks, you need to use a regular power drill or screwdriver.
One of the best impact drivers on the market today is the Makita XDT16Z 18V LXT Brushless Impact Driver. It features a brushless motor that delivers up to 50% longer runtime than brushed models, a 4-speed power selection that allows you to choose the optimal speed and torque for different applications, and an assist mode that helps prevent screw cam-out and cross-threading. It also has a quick-shift mode that automatically shifts from high speed to low speed for faster tightening, and a reverse rotation auto-stop mode that stops the rotation when the fastener is loosened.

Hammer Drill vs Impact Driver: What Are They Used For?
Now that you know what a hammer drill and an impact driver are and how they work, let’s see what they are used for in different scenarios.
- If you need to drill holes in concrete, brick, or stone, use a hammer drill with a masonry bit.
- If you need to drive screws or bolts into wood, metal, or plastic, use an impact driver with an impact-ready bit.
- If you need to drill holes in wood, metal, or plastic, use a power drill with a standard bit.
- If you need to drive delicate screws or fasteners into any material, use a power drill with a clutch setting.
Hammer Drill vs Impact Driver: Key Differences
Here are some key differences between hammer drills and impact drivers that you should keep in mind when choosing which one to buy or use:
- Hammer drills use standard bits with round shanks, while impact drivers use hex-shank bits that are specially designed for high torque.
- Hammer drills are larger and heavier than impact drivers, making them more difficult to use in tight spaces or for long periods.
- Hammer drills have more direct forward force than impact drivers, making them more suitable for drilling hard materials.
- Impact drivers have more rotational force than hammer drills, making them more suitable for driving large fasteners.
- Hammer drills have adjustable speed settings and can be used as normal power drills by turning off the hammer mode.
- Impact drivers have variable speed settings but cannot be used as normal power drills because they lack a clutch mechanism.
Conclusion
Hammer drills and impact drivers are both powerful and versatile tools that can help you complete various projects around your home or workplace. However, they have different strengths and weaknesses that make them suitable for different tasks. Knowing when to use each one can save you time, money, and frustration.
