tap and die set (AND SCREWS)

cheers guys, im feeling quite confident how to use it so far.
thanks for the advice, im gonna practice and practice on old bits of metal before i go near my bike with it though.

i was gonna fit a helicoil to my brake calipar mounting bolt, but in the end, it worked out cheaper to get a new calipar off ebay, so thats what i did.

ive heard about these expensive cutting agents, and how its better to use engine oil or kerosone instead.

ive tried google, but i couldnt find any good "how to" guides.

just been playing with the micrometer.

so an M5x1.75 means the bolt is 5mm wide, with a thread pitch of 1.75mm ?

im starting to understand already.

ive got a strange black tool in there that im not sure what it is

whilst you have the nomenclature correct for indicating pitch, i think you will find that a M5 thread has a 0.8mm pitch. Also diameter please not width.

is that standard M5 size then ? to have a 5mm (diamater) and a 0.8mm pitch ?

ok, ive got a tap in a M5 (which is a .8 thread) and a 2 die's in .8 pitch and .9 pitch.
why is this ?

sorry for all the questions, im eager to learn
