Hi Chris,

It's called a tapping head. It has 3 or 4 sets of "jaws" that have the thread size machined in them. When it reaches the correct depth of thread required, it releases. They cost anything from £200 through to £2000 plus the jaws.

In Topic: London fireworks display

I thought the London fireworks were excellant. They even rivelled Sydney this year, the brightness was lost on TV I think as the cameras couldn't adjust fast enough and "bleached" out. The noise must have been fantastic standing on the Embankment. 10 out of 10.
