I need some new MT2 collets for my Bridgeport M head.

An outfit named Discount machine Shop sells a set, but they aren't very
pricey, which makes me know they're off-shore stuff.

If you've ever bought from them, let me know what you thought of their
quality. I don't want collets with a lot of run-out, but I cannot seem to
find an authentic Bridgeport set. (for which I'd gladly pay)

Take a look at those from the little machine shop. I got their
collets and these work fine. Note that you may not need the set.

1/4 ]

Changing tools with a MT collet is a bit of a pain in that you
have to unseat the collet to get it to release. Consider an ER
collet adapter. The problem is that these use up some space from
the spindle to the table.
