Introduction: Using Hole Saw Without Arbor
How to use a how saw without an arbor.
Sometimes a situation will require that one needs to create a hole but cannot use an arbor with a drill bit.
1. Hole saw. In this case a Milwaukee 3/4 inch Hole Dozer was used
2. 1/2 inch hex bolt with the width that would just fit inside the threaded portion of the hole saw. Here I used a half inch bolt from Home Depot with the code "AVO" stamped on it.
3. Locking needle nose pliers
4. Optional: Slip-joint pliers
Step 1: Screw Bolt Into Hole Saw
1. Take the bolt and carefully screw it into the hole saw. Since the threads are not precisely aligned, try to work it in slowly. Because of the misalignment, it will only on it a short distance, but it should be enough.
Step 2: Lock Pliers Onto Hex Bolt
1. Lock the pliers onto the hex bolt.
2. Be sure the grip is firm so that it cannot move.
Step 3: Drill Hole
1. Start to slowly drill into the wood by pushing down into the wood. Rotate it back and forth.
2. If it is a small piece of wood, you could hold the wood at the same time.
3. You can also drill using the slip-joint pliers as well.
4. When using the slip-joint pliers, put the head of the bold all the way into the jaws for maximum hold.
