Spade Drill Bits - Building Stairway Tools

Spade drill bits come in a variety of different shapes and sizes and are usually used for drilling holes in the wood, but can be used in other building materials. They're not shaped like a normal spiral drill bit, they use a flat drill bit head, that comes in different widths, to create different sized holes.

Disadvantages For Using Spade Drill Bits

I can think of plenty and only have a handful of them, left over from the old days. They don't seem to last very long and require constant re-sharpening. Some hardwoods are difficult to drill through, when spade bits become dull, they will actually quit drilling and start smoking.

One time I was using a spade bit to drill into a flat piece of Oak. I became so frustrated, because I had just sharpened the drill bit and now it was starting to smoke, so I pulled it out and took it over to another scrap piece of Oak and started drilling, with the intention of seeing how long it would take, before the piece of wood caught on fire.

After a few minutes of what I like to refer to as blissful ignorance, I stopped throwing my little temper tantrum and went back to work. I've never been a big fan of them and probably never will.

Sometimes I have problems, keeping the drill bits lined up perfectly in the hole that I'm drilling. They will often pop out and damage the board you're trying to drill through.

Advantages For Using Spade Drill Bits

It's usually an inexpensive way for drilling large holes. If you only need to drill one hole or your drilling through something soft like drywall, a spade drill bit will get the job done. They're often cheaper than other drill bits also.
