If you are a DIY enthusiast or a professional contractor, you may have heard of an impact driver. An impact driver is a power tool that delivers high torque and speed, making it ideal for driving screws and bolts into various materials. But what is the most common use for an impact driver?
The most common use for an impact driver is driving long or large screws and bolts into wood, metal, plastic, and other materials. In this article, we will explain why an impact driver is the best tool for this task, what are the benefits and drawbacks of using it, and what are some tips and tricks to use it effectively.
Why an Impact Driver is the Best Tool for Driving Screws and Bolts
An impact driver is designed to drive fasteners into materials by applying a series of rotational impacts that increase the torque and reduce the resistance. Torque is the force that causes an object to rotate, and resistance is the force that opposes the rotation. By increasing the torque and reducing the resistance, an impact driver can drive screws and bolts faster and easier than a regular drill or a screwdriver.
A regular drill or a screwdriver relies on a constant rotational force to drive fasteners into materials. However, when the fastener encounters a lot of resistance, such as when it is long, large, or driven into a hard material, the rotational force may not be enough to overcome it. This can cause the drill or the screwdriver to slip, stall, or strip the fastener head, making the task difficult and frustrating.
An impact driver solves this problem by delivering short and powerful bursts of rotational force that create a hammering effect. This hammering effect breaks the resistance and drives the fastener deeper into the material, without slipping, stalling, or stripping. An impact driver also has a hexagonal chuck that holds the fastener securely, preventing it from wobbling or falling out.
What are the Benefits and Drawbacks of Using an Impact Driver
Using an impact driver to drive screws and bolts has many benefits, such as:
It is faster and easier. An impact driver can drive screws and bolts in a fraction of the time and effort that a regular drill or a screwdriver would take. This can save you a lot of time and energy, especially if you have a large project or multiple fasteners to drive.
It is more powerful and versatile. An impact driver can drive screws and bolts of various sizes and lengths, into various materials, with ease. It can handle tough tasks that a regular drill or a screwdriver may struggle with, such as driving lag bolts, deck screws, or self-tapping screws.
It is more compact and lightweight. An impact driver is usually smaller and lighter than a regular drill or a screwdriver, making it easier to handle and maneuver. It can also fit into tight or awkward spaces that a regular drill or a screwdriver may not be able to reach.
It is more comfortable and safer. An impact driver does not transfer the torque or the impact to your hand or wrist, making it more comfortable and less tiring to use. It also does not require a lot of pressure or force to drive the fastener, reducing the risk of injury or fatigue.
However, using an impact driver to drive screws and bolts also has some drawbacks, such as:
It is louder and more expensive. An impact driver produces a lot of noise and vibration, which can be annoying and disturbing. It also costs more than a regular drill or a screwdriver, which can be a factor to consider if you are on a budget or do not use it frequently.
It is less precise and adjustable. An impact driver does not have a clutch or a variable speed control, which means you cannot adjust the torque or the speed according to the fastener or the material. This can make it less precise and more prone to overdriving or underdriving the fastener, which can damage the fastener or the material.
It is less compatible and adaptable. An impact driver has a hexagonal chuck that only accepts hexagonal bits, which limits the types of fasteners and accessories that you can use with it. You may need to buy special bits or adapters to use an impact driver with other fasteners or accessories, such as drill bits, nut drivers, or sockets.
What are Some Tips and Tricks to Use an Impact Driver Effectively
If you want to use an impact driver to drive screws and bolts, here are some tips and tricks to help you get the best results:
Choose the right bit and fastener. Use a bit that matches the size and shape of the fastener head, and a fastener that is suitable for the material and the purpose. For example, use a Phillips bit for a Phillips screw, and a deck screw for a deck board. Make sure the bit and the fastener are compatible with an impact driver, and avoid using brittle or soft bits or fasteners that may break or deform under the impact.
Pre-drill a pilot hole. A pilot hole is a small hole that guides the fastener and reduces the resistance. Pre-drilling a pilot hole can make the task easier and faster, and prevent the material from splitting or cracking. Use a drill bit that is slightly smaller than the diameter of the fastener, and drill a hole that is slightly deeper than the length of the fastener.
Align the bit and the fastener. Hold the bit and the fastener perpendicular to the surface of the material, and make sure they are aligned and centered. This will ensure a smooth and straight driving, and prevent the bit or the fastener from slipping or wobbling.
Apply light pressure and trigger the tool. Press the bit and the fastener lightly against the material, and squeeze the trigger of the tool. You will hear and feel the impact driver delivering the rotational impacts. Do not apply too much pressure or trigger the tool too long, as this may overdrive or underdrive the fastener, or damage the bit or the material.
Stop when the fastener is flush or slightly countersunk. Release the trigger and the pressure when the fastener is flush or slightly countersunk with the surface of the material. Do not drive the fastener too deep or too shallow, as this may weaken the connection or leave a gap. You can use a depth gauge or a torque limiter to control the depth of the fastener.
To sum up, the most common use for an impact driver is driving long or large screws and bolts into wood, metal, plastic, and other materials. An impact driver is the best tool for this task because it delivers high torque and speed, making it faster and easier than a regular drill or a screwdriver. An impact driver also has many benefits, such as being more powerful, versatile, compact, lightweight, comfortable, and safer. However, an impact driver also has some drawbacks, such as being louder, more expensive, less precise, adjustable, compatible, and adaptable. Therefore, you should consider the pros and cons of using an impact driver, and follow some tips and tricks to use it effectively.
