An 8mm bit will have twice the cross sectional area of a " bit, so it should be that much stronger.
Take that a step further Roger and we have a 1/2" bit with over 2 1/2 times the cross sectional area of the 8mm bit!

Some of the shirts/cubs/stickers made me laugh, but the politics beneath the fanatical side of the 'go metric' group are just plain loopy (imho). I wasn't even aware that a fringe group like that existed.

If I came off as a 'metric only nut' in any way, I would like to correct that.

All I meant by 'default' system is when its actually used enough that it is on equal footing with imperial in actual use. That would get the prices for metric stuff on a par with imperial, and be a good thing.

The idea of 'metric only' road signs, education, package labeling or whatever, especially if accomplished by force (governmental decree, etc) is far more patently offensive to me than the inconvenience of having to do a little extra number crunching or buy a few more tools.
Bill, other countries have successfully made the changeover including Australia which was Imperial when I arrived in 1964 having left England, also an Imperial country. In February 1966 we started the changeover, firstly with the money where one pound became two dollars (creating many overnight millionaires!) and slowly it spread to everything. England I believe is well on the way to full metrication. At least America has a head start in as much as your coinage always has been metric.

Question What momentum

This poll is to convince companies that there are enough people ready to use these metric bits and guide bushings so they will begin production.
Mike you mentioned of a gradual shifting in the US in food and beverages have mostly made the switch over. I've been in the food and beverage industry for 30 years and I don't see hardly anything switched over.

Gene, I said that packaged food and beverages switched over. Perhaps that statement is not accurate and I should of said all packaged foods and beverages are now labeled with metric weights and measures. Every single item in my pantry from canned goods to boxes of cereal is labeled this way. Packaged meats are too; this is required by federal law. Soft drinks have been sold for years in half and 2 liter bottles.

I don't think that all our materials are imperial. For some time now, the woodworking shows on TV have said that 3/4" plywood, and other sizes, is slightly smaller. That is because it is metric. You will find that 3/4" plywood is probably 18mm thick. The same goes for other sizes. Another question is "is it 4'x8' or 1200mm x 2400mm?"

Thanks for expanding your thoughts on the matter even more Harry!

Money is a great example of how many different aspects of our lives, other than 'the craft' absolutely rely on 'standards' of measure.

Expanding the scope of consideration to consider staple foods (corn, wheat, rice etc), my research in the commodities markets taught me the unit of measure they are traded in is the Metric Ton, 1000 kg. In that context, the US has been metricized for quite some time!

People embrace change when they are convinced of a benefit. For me the biggest benefit in the context of woodworking is being able to use sheet goods produced in metric thicknesses. Using them provides me with a more appropriately sized product for the job and does so at a lower price.

Metric bits would be nic as I'm about to start a project where I'll be working with acrylic sheeting. The 1/4" material is truly 6mm so it would be nice to have that option available for routing dados. As it is, I'm going to see if I can get a 6mm end mill to work in my router...

Default Oh, the Duplicity

Now you tell me I must have TWO sets of bushings in the drawer. i already need two sets of wrenches - - - THREE - - - for my cars, SAE, METRIC and WHITWORTH. Just stick with the good old AMERICAN SAE standard.

I already have two table saws, two band saws, two jointers, several routers(can't say the number as my wife may see this) two scroll saws, etc.

The beauty of template guides in metric and Imperial is the fact that, in combination with both types of bits, extremely accurate off-sets can be achieved when the project calls for it, like in a lidded box.
