Why is it that no one makes a 1” spiral bit with ½" shank. Even the ¾“ spirals have a ¾" shank. What gives? I’ve never seen or heard of router with ¾” collet.

I don't think anyone would pay a 100.oo bucks plus for one carb.spiral bit.
3/4" is used in comm.hvy.duty routers.

I am just curious as to why you are interested in a 1" spiral bit?

If you are really wanting a 1" spiral bit, be prepared to pay a very high price for them. Usually electricians and plumbers use these.

If you are wanting to drill a 1" hole, either use an expansion bit or spade bit. Now days, they make extensions for use with the spade bits.
Just my $0.02 worth

I have several box joint router templates for ½ - ¾ and 1” joints. I use the ½ with 5/8 collars and spiral down cut bit mostly because less blow out as apposed to straight bits. I was thinking about doing box joint on router table and didn’t want to use 1” straight bit but after looking at the prices of spiral bits, I guess I’ll stick to ½” spiral bits.
Thanks for the inputs.

I think I may have misread this. Sorry, this hasn't been a very good week.

It's a matter of expense. Spirals are made from carbide rods and it takes a LOT of grinding just to make a normal one with the same cut diameter and shank diameter. Add the extra grinding required to reduce the shank diameter and the cost of the bit shoots even higher. Also, at that diameter there are carbide tipped bits with shear angles that can produce similar results.

SO, What's the difference between Left-hand and Right-Hand spiral router bits?
I know about Down- Cut and Up-cut . I use DC bits.
