CFM (Cubic Feet per Minute)

The volume of air consumed by the tool during operation. Understanding the CFM requirement ensures your air compressor can adequately supply the tool without pressure drops affecting performance.

Torque Range

The rotational force the screwdriver can apply, typically measured in Newton-metres (Nm). Adjustable torque settings prevent over-tightening and damage to delicate components or materials.

Free Speed (RPM)

The maximum rotational speed of the tool when operating without load, measured in revolutions per minute. Higher RPM generally means faster driving speeds for increased productivity.

Operating Pressure

The air pressure required for optimal performance, typically measured in PSI (pounds per square inch) or bar. Most air screwdrivers operate efficiently at 90 PSI or 6.2 bar.

Quick-Change Chuck

A mechanism allowing rapid bit changes without tools, improving efficiency when switching between different screw sizes or types during assembly work.

Inline vs Pistol Grip

Two common air screwdriver configurations. Inline designs offer better access in confined spaces, whilst pistol grip models provide more comfortable handling for extended use and better leverage.

Who Uses Air Screwdrivers?

Air screwdrivers are essential tools for numerous trades and industries requiring reliable, high-volume fastening capabilities:

• Automotive Technicians and Mechanics - for interior trim installation, dashboard assembly, and component fitment
• Manufacturing and Production Line Workers - assembling products, electronics, appliances, and consumer goods
• Cabinet Makers and Furniture Manufacturers - for repetitive fastening in flat-pack furniture and joinery assembly

• Maintenance Engineers - in factories, warehouses, and industrial facilities requiring regular equipment servicing
• Aerospace and Aviation Technicians - for precision assembly work requiring consistent torque application

How to Choose the Right Air Screwdrivers

Selecting the appropriate air screwdriver depends on several factors specific to your work requirements and existing workshop setup:

Torque Requirements: Consider the range of fastening tasks you'll perform. Light-duty assembly work may only need 2-5 Nm, whilst automotive and engineering applications might require 10-15 Nm or more. Models with adjustable torque settings offer the greatest versatility across different materials and screw sizes.

Grip Configuration: Pistol grip designs like the Sealey SA58 provide excellent ergonomics for repetitive use and better control when applying downward pressure. Inline models offer superior access in tight spaces and confined areas where a pistol grip won't fit comfortably.

Air Consumption and Compressor Compatibility: Check the tool's CFM requirements against your compressor's output capacity. An undersized compressor will struggle to maintain consistent pressure, affecting performance and productivity. Factor in other tools that may run simultaneously on the same air line.

Speed and Productivity: Higher RPM ratings generally translate to faster driving speeds, crucial for production environments. However, slower speeds with better torque control may be preferable for precision assembly work requiring consistent results.

Build Quality and Durability: Professional-grade models feature durable construction, efficient air motors, and better sealing against dust and moisture. Super duty variants like the Sealey SA623 are engineered for intensive daily use in demanding industrial environments.

Bit Compatibility: Verify the chuck size and bit-holding mechanism. Quarter-inch hex drives are industry standard and offer the widest accessory compatibility, whilst quick-change systems improve efficiency during multi-task operations.

Safety Information

Air screwdrivers are generally safe when used correctly, but proper practices should always be observed:

Personal Protective Equipment: Always wear appropriate safety glasses or goggles to protect against flying debris, loose screws, or material fragments. Consider hearing protection in production environments where multiple air tools operate simultaneously.

Air Supply Safety: Never exceed the manufacturer's recommended operating pressure, as this can cause tool damage, premature wear, or dangerous malfunctions. Install pressure regulators to maintain consistent, safe operating pressures. Always disconnect the air supply before changing bits or performing maintenance.

Proper Handling: Maintain a firm grip and ensure the bit is properly seated in the screw head before activating the trigger. Never point the tool at yourself or others, even when disconnected. Be aware that air screwdrivers can cause the bit to continue spinning briefly after releasing the trigger.

Maintenance Requirements: Regular lubrication with pneumatic tool oil is essential for safe operation and longevity. Check hoses regularly for wear, cracks, or damage that could cause sudden disconnection or air leaks. HSE guidelines recommend regular inspection of pneumatic tools in commercial environments to ensure continued safe operation.

Work Area Considerations: Ensure adequate workspace lighting and maintain an organised work area free from trip hazards. Coiled air hoses should be properly managed to prevent entanglement or workspace obstruction.

Frequently Asked Questions

Do I need an air compressor to use an air screwdriver?

Yes, air screwdrivers require a compressed air supply to operate. You'll need a suitable air compressor with adequate CFM output and tank capacity to maintain consistent pressure during use. Most air screwdrivers operate efficiently at 90 PSI (approximately 6.2 bar), so ensure your compressor can reliably deliver this pressure whilst running other tools if needed.

What are the advantages of air screwdrivers over electric cordless models?

Air screwdrivers offer several benefits including lighter weight (no heavy battery or motor), continuous operation without recharging downtime, consistent power output throughout the work period, and superior durability for high-volume production work. They're also safer in damp environments and generate less heat during extended use, reducing operator fatigue.

How do I maintain my air screwdriver?

Regular maintenance involves adding 2-3 drops of pneumatic tool oil into the air inlet before each use or at the start of each working day. This lubricates the internal air motor and prevents premature wear. Installing an inline FRL unit provides automatic lubrication and removes moisture from the air supply. Periodically check and clean the air inlet filter, and inspect the tool for any loose components or damage.

Can air screwdrivers be used for drilling?

No, air screwdrivers are specifically designed for driving and removing screws with controlled torque. They lack the power, chuck capacity, and structural design needed for drilling operations. For drilling tasks, you'll need a dedicated air drill which is engineered to handle the lateral forces and higher torque requirements of drilling applications.

What size air compressor do I need for an air screwdriver?

This depends on your specific tool's CFM requirements and intended use. For occasional use with a single air screwdriver, a 25-50 litre tank compressor delivering 5-8 CFM should suffice. For continuous production work or running multiple tools, consider a larger industrial compressor with a 100+ litre tank and higher CFM output to maintain consistent pressure without the motor constantly cycling.
