yes each handle has a different torque setting - I still plan to change the tips once I get another 1.3 allan key
I bought the 1.27 + handle and a 0.9 tip not realising they weren't really interchangeable. Most of my cars are 0.9mm - I bought the 1.27 because I didn't have a 1.27 wrench only a 0.9 and 1.5 because my cars use those sizes. and funnily enough it needs the 1.27 or 1.3 wrench to loosen it
the only size I don't have
cheers
