Whitworth CEI Tap And Die Set

Cycle Engineers’ Institute (CEI) / British Standard Cycle (BSC) tap & die set. If you have an old British motorcycle, chances are it has been around long enough for a ham-fisted mechanic to cross thread a bolt or try and use standard hardware on your delicate Whitworth threads.

This Whitworth CEI / BSC tap and die set is the answer to one of your problems, the cure to the headache that is your hobby. It has a starting and bottoming tap for each size, 1/4″-26, 5/16″-26, 3/8″-26, and 1/2″ taps. It also includes a round die, one each for the same sizes. Also included are a tap handle and a die handle and it all comes in a nice case to keep it organized and handy.

This is the perfect tool set to make assembly go easier by chasing your threads, fix buggered holes or bolts, and generally be extremely handy to have around when you just can’t run to the local hardware store for some Whitworth CEI hardware.

An essential kit for the British motorcycle owner turned enthusiast. I have one in my home motorcycle workshop and it has proved invaluable over the years!
