Turn Your Impact Wrench Into A Driver: Easy Attachment Tricks

attachment to turn impact wrench to driver

Impact wrenches and impact drivers are two very similar tools with very different purposes. The main difference between the two is that impact drivers are used for smaller fixings, such as screws, whereas impact wrenches are used for larger fixings, such as wheel nuts. Impact drivers usually have a hex drive, while impact wrenches usually have a square drive. Adapters can be used to make an impact driver turn a square attachment or an impact wrench turn a hex attachment. However, it is best to use each tool as the manufacturer intended.

Impact driver torque

Impact drivers are powerful tools that can be used for a variety of tasks, from driving screws to loosening or tightening nuts and bolts. They are designed to deliver high torque impulses, making them much more powerful than traditional drills or screwdrivers. However, this also means that controlling the torque of an impact driver can be challenging.

Understanding Torque

Torque is the rotational force that causes an object to rotate or twist. In the context of impact drivers, torque is what allows the tool to drive screws or tighten nuts and bolts. The torque of an impact driver is typically measured in Newton-meters (Nm) or foot-pounds (ft-lbs).

Controlling Torque with an Impact Driver

Unlike traditional drills, impact drivers do not have a clutch to adjust the torque directly. This can make it difficult to achieve a consistent torque when driving multiple fasteners. Here are some techniques and tools that can help you control the torque of an impact driver:

  • Adapter Selection: Choosing the right adapter for your impact driver can help you control the torque. Adapters with a smaller hex size, such as 1/4", will reduce the torque transferred to the fastener.
  • Variable Speed Settings: Most impact drivers have variable speed settings. By using a lower speed setting, you can reduce the torque output of the tool.
  • Manual Torque Wrench: If you need to achieve a precise torque, you can use a manual torque wrench to tighten the fasteners after driving them with the impact driver.
  • Impact Driver Sockets: Using impact-rated sockets with your impact driver can help you control the torque. These sockets are designed to flex and absorb some of the torque, preventing over-tightening.
  • Torque Limiting Extension Bars: These extensions are designed to flex and disconnect from the fastener when a predefined torque value is reached, preventing over-tightening.
  • Air Pressure Adjustment: For pneumatic impact drivers, you can adjust the air pressure to control the torque output. Lower air pressure will result in lower torque.

Advantages of High Torque

While controlling torque is important to prevent over-tightening and potential damage to fasteners or workpieces, there are also advantages to having a high-torque impact driver:

  • Versatility: A high-torque impact driver can replace the need for a separate impact wrench, as it can handle a wider range of tasks.
  • Faster Work: With more torque, you can drive fasteners faster and more efficiently, reducing the time required for your projects.

Disadvantages of High Torque

There are also some drawbacks to using a high-torque impact driver:

  • Adapter Breakage: When using high torque settings or adapters with a larger hex size, there is an increased risk of breaking the adapter, especially when working with hard metal fasteners.
  • Over-tightening: Without proper control, a high-torque impact driver can easily over-tighten fasteners, potentially damaging them or the workpiece.

Impact drivers are powerful tools that can significantly speed up your work. However, it is important to understand how to control their torque to avoid potential damage. By selecting the right adapters, using variable speed settings, and employing additional tools like torque-limiting extensions, you can effectively manage the torque of your impact driver and make the most of its capabilities.

Impact wrench torque

An impact wrench is a tool that delivers a high torque output with minimal input, making it a useful tool for a range of tasks. The torque output of an impact wrench is dependent on a few factors, and there are a variety of attachments available that can turn an impact wrench into a driver.

Torque Settings

Impact wrenches have torque settings, which are often not specific torque values. Instead, the torque output increases the longer the trigger is held. For example, an impact wrench on setting '3' might deliver 100 ft/lbs of torque if the trigger is held for 2 seconds, and 120 ft/lbs if held for 4 seconds.

Torque Sticks and Torque Wrenches

To determine the exact torque being applied, a torque wrench or torque sticks can be used. Torque sticks are accurate when used with the same impact wrench, and they are a good investment if you are frequently using your impact wrench for a range of tasks.

Impact Wrench Attachments

There are a variety of impact wrench attachments available that can turn your wrench into a driver. These include:

  • Drill chuck adapters, which can quickly convert your impact wrench into a power drill.
  • Socket adapters, which allow you to use your impact wrench with different sized sockets.
  • Right-angle drill attachments, which allow you to use your impact wrench in tight spaces.
  • Reducers, which reduce the drive size of your impact wrench.
  • Universal joints, which allow your impact wrench to pivot and reach difficult areas.

These attachments, coupled with the adjustable torque settings of an impact wrench, make it a versatile tool for a wide range of tasks.

Impact driver size and weight

The size and weight of an impact driver are important factors to consider when choosing the right tool for the job. Here are some insights into impact driver size and weight to help you make an informed decision:

Impact Driver Drive Styles

Impact drivers typically use a 1/4-inch hex collet that accepts 1/4-inch hex shank bits. This is the most common size and style for impact drivers, and it is suitable for a wide range of applications. However, there are also right-angle impact drivers and palm-sized pressure-driven models available.

Impact Driver Power Sources

Impact drivers are predominantly cordless, with 12V, 18V, and 20V Max batteries being the most popular options. Corded impact drivers are also available but less commonly used. The cordless feature provides convenience and mobility, making them ideal for construction sites and other outdoor applications.

Impact Driver Torque

Impact drivers typically offer higher torque than impact wrenches, with some models exceeding 2000 in-lbs of torque (approximately 167 ft-lbs). For professional use, an impact driver with at least 1600 in-lbs (125 ft-lbs) of torque is recommended. Impact drivers usually measure torque in inch-pounds (in-lbs), while impact wrenches use foot-pounds (ft-lbs).

Impact Driver Speed

Impact drivers tend to have higher speeds compared to impact wrenches, with maximum RPMs reaching 3600 or more. This makes them efficient for driving screws and smaller fasteners.

Impact drivers are generally more compact and lightweight than impact wrenches, making them easier to manoeuvre in tight spaces and reducing fatigue during prolonged use. The size and weight of an impact driver can vary depending on the power level and voltage of the battery.

When choosing an impact driver, consider the specific applications you will be using it for and select a model that offers the right balance of power, size, and weight to suit your needs.

Frequently asked questions

Impact drivers and impact wrenches have a lot in common, but there are some key differences. Impact drivers usually have a hex drive and are compatible with hexagonal bits and attachments, typically measuring 1/4 inch across. Impact wrenches, on the other hand, usually have a square drive and are compatible with square bits and attachments in various sizes, including 1/4 inch, 3/8 inch, or 1/2 inch. Impact drivers are generally smaller and lighter, while impact wrenches are designed to deliver more power and torque.

Yes, you can use an impact driver as an impact wrench if you have the right adapter. However, keep in mind that impact drivers have much less torque than impact wrenches, so they may not be suitable for heavier-duty tasks or larger fixings.

There are several adapters available on the market that can be used to turn an impact wrench into a driver. Some recommended options include the DEWALT Right Angle Attachment, the LEXIVON Impact Grade Socket Adapter Set, and the Neiko 30275A Impact Wrench Adapter. These adapters can help you use your impact wrench with different types of bits and attachments.
