Makita's 24-volt BTW200 offers a maximum torque of 200Nm when in high speed, and 150Nm in its lower speed setting, achieved by delivering up to 3,000 impacts per minute in high or 2,500 in low.
Careful use of the trigger can restrict impacts and tightening force, ahead of final tightening by torque wrench. Though getting close to the desired torque setting is achieved, somewhat simply, by timing. For example, getting an M12x50 high tensile bolt up to 100Nm takes five seconds using the low speed setting, and just one second at high speed.
It packs plenty of power and will reduce fastening times and make light work of stubborn nuts and bolts in the field with suitable 1/2in impact sockets. But we found the BTW200 to be quite heavy and unwieldy, though the ‘O-ring and pin' socket attachment system is brilliant and comfortably withstands the tool's aggressive action.
Some savvy shopping should get this model for £540 including
