I've been trying to find a specialized tool,
and I've had a hard time.

Does anyone here know of a source for 1 1/2"
masonry bits? I know I can find core bits,
but they won't do.

I need to be able to make a 1 1/2" diameter
by 1" deep hole in some soft stone (sandstone,
limestone), without percussion and without
penetrating fully through the stone.

I can find up to 1" diameter bits with no problem,
but, above that I'm hitting a dry well.

Any ideas?
