A few years back I picked up this set which covers M3 to M12 including M3.5. I didn't expect much but it has been really good for my occasional needs.

Thank you everyone, really great information from you all and i'm learning yet again
I'm in the mind to buy a set, as i would rather it be waiting to be used rather than waiting to get the bit i have not got 
I did mention this to someone i know and they recommended a set from Facom, does anyone know if they are any good ? many thanks. 1996 Golf Blue 300Tdi 110 Pick up. Keeper. Clayton. |

Used my Draper taps again today for cleaning threads of torque convertor from Loctite and re-threading exhaust manifolds for new studs.

This is what happened to me:
Bought cheap set and used only two of them regularly until I finally snapped one in the work (!). Bought replacement at quality shop, realised the difference, bought standard, intermediate and bottoming taps in those two sizes and a few more as need arised. The original set never gets used except perhaps for the dies when I need to clean up a stud or extend the thread on a bolt etc. Very bodgy! In general though, taps are used much more often than dies. I also discovered since the style of tap for through-hole threads that lets you just hand drill them straight through (in soft metals) - it's designed such the swarf falls downward, rather than spiral up. I'll hunt out the design, great time saver in certain circumstances. Conclusion: if it were me again, I'd buy quality individual taps with appropriate decimal drills (*) as I need them - perhaps a cheapy too and push it harder on some scrap stock to see how early it breaks, you'll get a feel for it that way. * oh and a pitch gauge and vernier calipers Solved the bowel problem, working on the consonants... |

^^threads on bolts are directly formed and then perhaps galv coated/hardened etc.
'Cleaning' them with a die (as I do myself) almost always results in swarf, whose removal could (?) lead to unintended consequences like corrosion and loss of strength. Not that I've ever had anything bad happen personally, but I just note it ... Solved the bowel problem, working on the consonants... |

As Agentmulder says, almost all bolts and setscrews now have rolled threads. Whilst it is OK to clean them with a die or die-nut it is not advisable to cut the thread of a bolt longer. Get one the right length to start with.

Horses for courses? I clean up or "chase" bolts (for example when changing the anodes on my boat) with a die-nut, but I wouldn't attack them with a split die.
