    The Chicago Pneumatic CP9427 3/8'' air ratchet wrench delivers the kind of compact power and precision that keeps production lines moving and workshop downtime to a minimum. Built for professionals who demand reliability in tight spaces, this pneumatic ratchet wrench combines a smooth 270 RPM free speed with a maximum reverse torque of 35 Nm, giving technicians confident control across a broad range of fastening tasks without sacrificing speed or accuracy. The CP9427 operates with a working torque range of 7 Nm to 35 Nm in reverse, making it exceptionally versatile for both delicate assemblies and more demanding removal work. Its 3/8'' square drive is the industry-standard size for mid-range fasteners, and the tool's well-balanced construction reduces operator fatigue during extended use - a genuine advantage over heavier competing models in the air ratchet wrench category. Sourced from a brand trusted across automotive, industrial, and manufacturing sectors, this Chicago Pneumatic ratchet wrench sits comfortably alongside other respected tools in the CP range, including the popular cp828 air ratchet and cp828h series, but brings its own distinct ergonomic and performance advantages to the workbench. The pneumatic ratchet wrench design means consistent torque delivery with every cycle, powered entirely by compressed air for low-maintenance operation. Ideal for automotive technicians working on suspension components, engine bays, and brake assemblies where access is restricted and repeatability matters most.Product Feature: High power (27 ft.lbs / 35 Nm) for better productivity Extremely compact tool (5.1" / 130 mm) that enables improved comfort and access in hard to reach places About MachineRefurb: MachineRefurb is an e-commerce platform specialising in replacement parts, spares and consumables for construction, agriculture and industrial machinery, serving customers across Ireland, the United Kingdom and Europe.
