Industrial tightening operations are extremely demanding, requiring a tool that is ergonomic enough to be used over an entire shift and durable enough to survive in a production environment. Over time, manufacturers transitioned from pneumatic assembly tools to high-powered, corded DC electric assembly tools. That transition lowered noise, increased durability and improved ergonomics. Additionally, these tools provided data and advanced error proofing to improve quality and control. The change was revolutionary. Now, the next major change in tightening operations is occurring: the transition to cordless assembly tools.
