For larger sized holes up to about 1" or 1 1/8", we always use a step bit for very accurate holes with a nice surface finish. Anything larger than that hole saws become basically the only option.
Step bits are very quiet and smooth when sharp, but it is best practice to use oil when necessary to cool it off for a little bit. If you had to choose one tool, I would go with the step bit.
Where can I buy the awesomeness that you used on that? Do they sell it at andymark? - HansJ [more]
