Quality tool made in the U.K. (not to be confused with the slightly cheaper versions found elsewhere)
It took 3 practice attempts of both the DIN and SAE models to work out how the tool likes the pipe to be cut, deburred, and how best to tighten the die.
With the DIN version I found it gave perfect results when presented with a cleanly cut pipe, with a slight deburr to the inside, tightening the die like a thread tap, half turn, back off, half turn etc…
With the SAE version, the pipe required a cleanly cut pipe, with a slight deburr to the inside and a fair deburr to the outside of the pipe, with no backing off of either die when tightening, again, perfect results.
I am very happy with both tools, and cannot imagine how the much more expensive brake flaring tools could give better results.
I have now remade all the brake lines on my 40 year old Ford, and neither the DIN or SAE tool show any signs of use.
