Can a spade bit be used on metal?
Spade bits are only for wood! Not for metal. It might work on thin metal but you’ll trash the bit and make a crappy hole.
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.
What is the main disadvantage to boring holes with spade bits?

When would you use a auger drill bit?
Auger drill bits are bits used to drill holes into wood. They are commonly used for boring holes into bulkheads and general timber applications.

Does drill rpm matter?
For example, a drill that runs at 1500 rpm is an average maximum. Anything with less than 1500 max rpm will not be a good choice for big jobs. Many top-rated cordless drills feature brushless motors, and these can achieve a higher rpm with less electricity, making them more powerful, durable and energy efficient.
What speed run a drill press for wood?
The best speed for drilling wood depends on the diameter of the bit and the material drilled. Larger diameter bits require a slower speed, as do hardwoods.

Do you drill wood fast or slow?
Finding the right speed is mostly a matter of experience. However, we do recommend starting slowly and carefully increasing the speed.
