Impact drivers are ideal for driving in smaller screws

Impact drivers are also more compact and lighter than cordless impact wrenches. They are capable of drilling with bits that have a compatible shank. They are also great for situations where you need to drive in a lot of screws, such as when building a shed.

Additionally, impact drivers have become smaller over the years and now deliver more torque than your standard drill. They are also much more convenient than changing out the bit on your drill. For instance, the Milwaukee SURGE 12-Volt Lithium-Ion Brushless Cordless 1/4 in. Hex Impact Driver Compact Kit offers 50 in-lbs of torque, 3400 blows per minute, and is smaller than any other 12v equivalent at 7.8” tall and 5.2” wide.

If you're just getting started and your primary focus is construction or carpentry projects, it's recommended to get an 18V/20V max impact driver first.

Impact wrenches are better for loosening and fastening large nuts and bolts

Impact wrenches are ideal for loosening and fastening large nuts and bolts. They are larger and deliver more power than impact drivers, which are designed for driving in smaller screws. Impact wrenches usually have a 3/8" square drive or larger, whereas impact drivers use a 1/4" hex drive.

Impact wrenches are typically used for socket-based applications and are designed for working on vehicles. They are also used for loosening and fastening hex head fasteners such as nuts and bolts or timber screws. Impact wrenches are heavier and bulkier than impact drivers and produce significantly more power (torque). On average, impact wrenches are six times more powerful than impact drivers.

While impact drivers can be used to loosen and fasten nuts and bolts with the help of socket adapters, it is not their intended use. Impact drivers are primarily designed for driving screws and are ideal for situations where standard drills lack sufficient power. They are smaller and more compact than impact wrenches, making them easier to handle and manoeuvre in tight spaces.

Impact wrenches cover a much larger range of performance levels and have more specialty versions. They are available in corded and cordless versions, but the classic impact wrench sound is powered by air. Impact wrenches are ideal for extreme power applications, with larger sizes mainly used for industrial-level and heavy equipment tasks.

Impact wrenches are heavier and bulkier than impact drivers

When it comes to impact drivers versus impact wrenches, one of the most notable differences is their size and weight. Impact wrenches are typically heavier and bulkier than impact drivers, which can make a big difference in how they are used and the tasks they are suited for.

Impact drivers are generally smaller and more compact, making them ideal for working in tight spaces or handling smaller screws. They usually feature a 1/4-inch hex collet that accepts 1/4-inch hex shank bits. This design makes them perfect for driving in smaller screws and fasteners, and they are commonly used in woodworking and construction applications.

On the other hand, impact wrenches are larger and deliver more power. They often have a square drive, typically starting at 3/8-inch and going up to 1/2-inch or larger. This larger drive size means that impact wrenches are designed for loosening and fastening larger nuts and bolts, such as those found in automotive work. The increased power and torque of impact wrenches make them ideal for breaking free seized nuts and bolts.

The size and weight difference between impact drivers and impact wrenches can also be attributed to their power sources. While both tools can be cordless, impact wrenches are classically associated with the powerful pneumatic sound of a mechanic's shop. Cordless impact wrenches tend to be heavier and bulkier than their pneumatic counterparts due to the weight of the battery.

Additionally, the size and weight of impact wrenches often increase with their power level. Higher torque impact wrenches, such as those used for industrial or heavy equipment applications, can be significantly larger and heavier than impact drivers. This makes impact drivers a more lightweight and manoeuvrable option for tasks that don't require the same level of power.

Impact drivers are more compact and lightweight than impact wrenches

When it comes to impact drivers vs impact wrenches, one of the most notable differences is their size and weight. Impact drivers are known for being more compact and lightweight compared to impact wrenches, which makes them easier to handle and manoeuvre, especially in tight spaces. This feature is particularly advantageous when working on small engines or in confined areas.

The compact design of impact drivers is a result of their intended use. Impact drivers are typically designed for driving in smaller screws and fasteners, whereas impact wrenches are built for handling larger nuts and bolts. The smaller size of impact drivers allows them to access tight spaces and provides greater control during operation.

In addition to their compact size, impact drivers often come in different forms, such as the standard pistol grip style and the right-angle design, which further enhances their versatility and ease of use in various situations.

While impact wrenches are generally larger and bulkier, it's worth noting that they also come in a range of sizes, including compact models. These compact impact wrenches usually have a 1/4-inch square drive, while the more common 3/8-inch drives offer a balance between size and performance.

When choosing between an impact driver and an impact wrench, it's important to consider the specific task at hand. For tasks requiring more power and torque, such as loosening or fastening large nuts and bolts, an impact wrench is the better option. On the other hand, for driving screws, especially in confined spaces or for light automotive work, an impact driver's smaller size and lighter weight make it a more practical choice.

Impact wrenches are more powerful than impact drivers

Impact wrenches and impact drivers are both tools that use a rotational hammering action to twist fasteners. However, impact wrenches are more powerful than impact drivers.

Impact wrenches are larger and deliver more power than impact drivers. They are typically used for loosening and fastening large nuts and bolts. Impact wrenches usually have a square drive that you attach a socket to, and they come in a range of sizes and performance levels. The smallest impact wrenches have a 1/4-inch square drive, while 3/8-inch drives are more common on compact models. The most common size is the 1/2-inch impact wrench, and there are also larger 3/4-inch and 1-inch drives for industrial-level and heavy equipment use.

Impact drivers, on the other hand, are usually smaller and use a 1/4-inch hex drive for driving in smaller screws. They are typically used for driving screws and can also be used for drilling with compatible bits. While some impact drivers can deliver over 1600 in-lbs (125 ft-lbs) of torque, which is impressive, impact wrenches start around 100 ft-lbs (1200 in-lbs) and can deliver well over 1000 ft-lbs (12,000 in-lbs) of torque.

In addition to delivering more power, impact wrenches are also better suited for certain types of fasteners. Impact wrenches are designed for use with hex head fasteners such as nuts and bolts or timber screws, while impact drivers are typically used with fasteners that require a driver bit, such as slotted, Phillips, square, or Torx fasteners.

When choosing between an impact driver and an impact wrench, it's important to consider the type of work you'll be doing. If you need to loosen or fasten large nuts and bolts, an impact wrench is the better choice. If you're primarily working with smaller screws and fasteners that require a driver bit, an impact driver will be more suitable.
