How to adjust torque on drill?
Adjust the clutch. Each drill has a twistable collar to adjust the torque, often with a series of numbers on it. The higher the number, the more torque (rotational force) the drill will apply. If you are having trouble penetrating the material, increase the torque. If you are over-driving screws (burying them too deep), or if drilling too deep could damage something, lower the torque.
How to replace a drill bit?
Fit the drill bit firmly into the chuck. The chuck is the clamp in the "jaws" of the drill. This holds the drill bit in place as it spins. To replace a drill bit, make sure the drill is off (and unplugged if corded), then loosen the chuck by rotating it.

What bit to use for a drill press?
Cutting precise, large-diameter holes with a portable power drill or drill press can be done with a variety of drill bit attachments, including a hole saw, spade bit, or Forstner bit. While each one has its advantages, the Forstner typically drills the cleanest holes. But Forstner bits can also be tricky to use in a portable (handheld) drill, as they're better suited for use in a drill press. When used in a portable drill, a Forstner bit has a tendency to "walk" or drift away from the center, especially at the beginning of the operation. There's a simple solution to this problem, and it can help whether you're drilling into virgin material or if trying to enlarge an existing hole with a Forstner bit.

Do Forstner bits work with drill press?
Forstner bits work very well with drill presses for a few reasons. The drill press has a depth stop to keep your bit from going deeper than desired. It also has a speed control which is needed when using these types of drill bits. The forstner bit is designed to be used at slower speeds.
Can a spade bit drill holes?
If your wood project calls for a lot of dowels the forstner bit will be more precise not only in depth but diameter. Sure a spade bit can drill a hole but the tear out could keep the dowels from fitting into the holes snug.
