How to Use a Spade Bit

How to Use a Spade Bit. How do you bore a big hole? Use a spade bit to make a hole larger than you can with a regular drill bit. Here's how.

Step 1

Identify a spade bit by its shape: it looks a little like a flat shovel with a point in the center of the end.

Step 2

Make a pilot hole first with a regular 1/8-inch bit at the center of where your hole will be.

Step 3

Line the point of the spade bit up with the pilot hole.

Step 4

Start the drill motor at a slow speed and hold it steady as the bit grabs the wood.

Step 5

Increase the drill speed steadily.

Step 6

Drill completely through the workpiece and back the bit out smoothly with the drill still going.
