When to Use This Impact Wrench
The SSW18LTX400BL is Metabo’s mid-range 1/2″ impact wrench for tradespeople on the CAS battery platform. The 12 speed/torque levels give you more precise control than competitors with 3 or 4 settings, valuable for assembly work where consistent torque prevents thread damage. Choose this over the SSW18LTX300BL when you need the extra torque for wheel nuts and heavier bolts, or over the SSW18LTX800BL when 400Nm is sufficient and you want a lighter tool.
