How to attach a detachable arbor

Shop for Hole saws

Arbors will typically outlast a hole saw but there may come a time when you need to replace it due to damage or wear and tear. You will also need to know how to remove and attach it if you are using the same arbor with a range of different hole saws.

Step 1 – Insert collar threads

Lift the collar base and insert collar threads into the centre hole of your appropriately-sized hole saw.

Step 2 – Screw on until tight

Thread the hole saw onto the threads and screw until it is tight.

Step 3 – Align drive pins

Align the drive pins with the holes in the collar and insert them.

Step 4 – Lock on hole saw

The pins on the collar should align with the smaller holes on the base of the hole saw. These will lock the hole saw on to the arbor.
