Review on 🧰 Bosch PCM38 MC Mandrel with Convenient Quick Change Feature by Bennie Wilks

Very durable and well designed. The quick swap function is great. With the pilot hole saw and hole saw in place, there is no vibration. For the reviewer who said the pilot jet keeps falling out, then it shouldn't quite be. You must pull back the outer sleeve (e.g. air hose connector) to fully insert the pilot jet. I liked the solution so much that I merged it with adapters for non-Bosch hole saws.
