  6. Use the two wrenches to tighten the hole saw onto the mandrel so that it doesn’t come loose when you drill.
  7. Pick a drill of your choice and install the mandrel of the hole saw onto the drill and tighten.
  8. You are now ready to start drilling nifty circular holes with your set of hole saws!
  9. Repeat the procedure if you want to change the hole saw and/or mandrel

How to Use a Hole Saw

After the assembly of the hole saw kit, the next step is to use it to drill holes. While most handymen know how to use a hole saw, a good number does not or rather does not know how to use it effectively and safely. The following is a procedure for using a hole saw.

    Warning: Ensure that you wear protective clothes, glasses, and heavy-duty pair of gloves before you begin to drill holes.

  1. First, identify where you want to drill a hole and mark the center with a pencil.
  2. Drill a pilot hole into the mark with a drill bit.
  3. Fit the hole saw and mandrel assembly into the drill. Ensure that the pilot bit sticks out further than the hole saw itself.
  4. Grip the drill tightly perpendicularly onto the material you want to drill through the pilot hole.
  5. Start to operate the drill. The pilot bit will guide the drill.
  6. If you are working on a thick sheet of wood, just drill about halfway through and flip it over. The pilot hole will give you a perfect index to finish the cut.
  7. Drilling wood from both sides gives you a clean cut that does not have any tear out.
  8. Hole saws larger than 3″ tend to grab when you start to cut in. That pull may cause strain or even twist on your wrist. For such a case, use a drill that has a handle on it so that you can have both the drill and the handle against your body to keep it from twisting.
