Buying verdict
Choose the DCF870B when lower impact noise and smooth hydraulic fastening matter more than chasing the highest published torque number. It is particularly relevant for occupied buildings, cabinetry and interior work.
What to know before buying
Hydraulic impact drivers solve a different problem than high-torque impact drivers. The DCF870B belongs in comparisons focused on noise, control and working environment rather than simply ranking models by torque.
