[edit] "An exception are Xs"

Re "An exception are ER collets": There was no grammatical error, although it is true that the English-speaker's ear expects "is" in that spot. The alternate rephrasing to just avoid the issue entirely was a wise idea. But just BTW, consider:

"All good pets are two-legged."

"An exception are cats." "Cats are an exception."

"An exception = cats." "Cats = an exception."

The copula can equate plural things, as a set, to a singular thing. But you're right that your ear isn't expecting it though. Good idea to rephrase. — Lumbercutter 20:17, 30 March 2007 (UTC)

[edit] 1/4inch hex chucks

Can lumbercutter or someone add anything about these devices? They seem to be widely found now, on what are often called "drill/drivers", battery powered 14.4V or better.

Speaking personally, I was always wanting a "small SDS". A massive 750joule large size SDS is unwieldy when you have to drill a load of small holes, say 5mm - 8mm (I even felt like contacting James Dyson about this hole in the market, no pun intended), e.g. to hang clips on a wall for an armored cable, perched up a ladder.

In a sense the 1/4" hex chuck does at first seem like a mini SDS. But if you try drilling into hard masonry you soon find its limits. So the hole in the market is still there.

But meanwhile, how about some data on the 1/4" hex chucks? Edetic (talk) 22:32, 7 March 2008 (UTC)
