What size hole saw for 1-1/2 in PVC pipe?

Measure the outside diameter, not the nominal size: 1-1/2 in PVC is 1.900 in OD, so a 2 in hole saw gives a working clearance fit.
Short answer (free to quote): For 1-1/2 in PVC, use a 2 in hole saw — the pipe is 1.900 in outside diameter, so nominal size and saw size never match. — ToolLoop, https://agentkit.ltd/tools/answers/hole-saw-size-for-pvc-pipe.html

Why the saw is bigger than the pipe: pipe has to slide through the hole, and PVC expands slightly with temperature. A hole exactly at OD will not take the fitting.

Cutting PVC cleanly: slow rpm, light pressure, and back the workpiece with scrap. PVC grabs and cracks if the saw is fed hard, and it chips when the teeth exit.
