AIRCAT 811 1⁄4” 30° Flex Head Ratchet Wrench. The 811 produces 35 ft-lbs. of maximum torques and a fast rundown speed of 240 RPM. The AIRCAT “silencing technology” reduces the tool noise to just 76 dBA. The three position 30° flex head allows the user to get into tight spots that normal straight ratchets are unable. The feather or “variable” speed trigger provides precise speed control. This tool is perfect for working on smaller fasteners in tight or challenging spaces.
