With the help of a hole saw, you can make round holes in different materials. Hole saws are suitable when drilling thick materials because the pilot bit of a hole saw can break or split a thin material.
So, is it possible to avoid breaking or splitting of a thin material when making a hole using a hole saw? Yes, you can. When drilling a large diameter hole, using a hole is mandatory without a pilot bit.
Let’s learn how to use a hole saw without pilot bit reading this article.
Process of Using a Hole Saw Without Pilot Bit
- Hex-head wrench (1/16”)
- Guide plate to match the hole saw
- Hand clamps (2)
- Drill (cordless)
- ¾” X 4” X 4” scrap wood
Step 01: The bit needs to take out from the saw; by unscrewing the collet you can do so. Take assistance from a 1/16” hex-head wrench to remove the drill bit. Then again, the collet needs to be screwed onto the hole saw.
Step 02: Now, it is time to clamp the object onto the guide plate. Ensure you clamped the object in the position where you want to drill. If the clamp can’t hold the material, hold it using your hand.
Step 03: The hole saw needs to be inserted without the pilot bit into the drill.
Step 04: Next, the hole saw requires to be inserted into the guide plate. Turn the tool on and start drilling with less speed. Allow the teeth to create a perimeter hole. Don’t stop until you drill ½” deep. After making the hole, turn the tool off.
Step 05: Hold the drill at your arm’s length, it is necessary to generate enough pressure. Ensure you hold the drill into the hole as you move backward and confirm your position, which should be aligned vertically. Whenever required, adjust. And then drilling should be continued.
Step 06: If you experience a bind or burn in the hole when drilling, take out the hole saw from the hole. Clean the hole by blowing the dust. Then again, start drilling. This way, drilling through an object is perfect and you will have access to the back of it. While you are within approximately ½” of the entrance to the other side of the wood, hold a scrap wood piece behind the drilled wood. Hold the wood piece tightly against the back where the saw creates the hole. Let the drill create a complete hole, and the hole saw will get stopped by the scrap wood piece.
A hole saw is prone to kick back, so be prepared for that when working with it. Don’t forget to brace your arms and wrist throughout the drilling process.
