AWTOOLS llave de carraca neumática mini 1/4" accionamiento 27 Nm

27 Nm of maximum torque from a compact 160 mm body — this AWTOOLS mini air ratchet wrench brings serious fastening power to tight engine bays and confined workspaces. The 1/4" square drive spins at 250 RPM under 6.3 bar, making quick work of small fasteners where a full-size ratchet simply won't fit.

Overview

Engineered for professional mechanics and serious DIYers, the AWTOOLS 679529 pneumatic ratchet combines an aluminum housing with a rear exhaust to keep airflow away from the work area. The lever throttle gives precise speed control, while the reversible mechanism lets you switch between tightening and loosening without changing grip. At just 160 mm long, it slips into spaces that defeat bulkier tools, yet it still delivers the torque needed for stubborn bolts.
