Are Forstner bits better than spade bits?
When it comes to Forstner bits vs spade bits, both make excellent tools for boring holes in wood. They differ significantly in terms of use case, speed, and cost. Spade bits are ideal for rough construction work with softwood, while Forstner bits are geared towards precision woodworking with hardwoods or softwoods.
Is a spade bit better than a hole saw?
Hole saws are much more cleaner than the spade bits. It can go all through the wood. Unlike spade bits, hole saws provide a cleaner finish. If you are using a quality hole saw, you should be able to avoid splinters.

Which drill bits are for wood?

Why drilled holes are over sized in drilling operation?
Oversized holes can be caused by too much lip relief, unequal lip heights and a worn drill bushing. Below are possible solutions to each of the causes. Short tool life can be caused by the fact that only one lip on the drill is cutting or drill dwelling.
