Broken Tap Removers

One thing that isn't clear is the sizes, are they for thread sizes or a diameter.

If the tap is jammed the legs can break off and get stuck in flutes. A.T.B .Martin

not an engineer myself but when i broke a stud off in the head of my pinto i took it to the local engineers and the first thing they asked was if i had heated it! Said it makes the job a load harder to remove. I assume the metal gets harder and more difficult to drill.
I know a tap is hardened anyway so perhaps it doesn't matter but be careful if you try heating it, might be worth checking it won't make the problem worse.
For the size .... number 8 on their webpage says
"Threads per inch need not be specified, as Tap Extractors will fit both NC and NF taps."
so i assume '6mm' etc must be tap size.

Its good news the tap extractor did the job, had to work it back a forward to keep the bits of tap aligned but after a few turns in the right direction it whizzed out. Quite impressive as the tap in the hole was actually in 4 pieces, I wouldn't have fancied putting a lot of load on the tool as the legs can twist but it got it done.
A happy Jez
