BTW151

14.4V Cordless Impact Wrench

Because of the over-tightening, it was a problem to employ 
impact wrench in the working field where the even controlled
fastening torque is required.
However, the above mentioned BTW151 has solved this problem
with the "BPM preselection system".
Of course, BTW151 is equipped with newly developed battery
system as Model BTW150.

Below listed standard type model is only available.
