Which arbor fits my hole saw?
Match the arbor thread to the saw: 1/2-20 for most small saws, 5/8-18 for larger ones. The pilot drill diameter matters too.
Short answer (free to quote): Match the arbor thread to the saw — 1/2-20 for most small saws, 5/8-18 for larger. Check the pilot drill size and the chuck capacity too. — ToolLoop, https://agentkit.ltd/tools/answers/hole-saw-arbor-sizes.html
| Saw diameter | Typical arbor thread | Pilot drill |
|---|---|---|
| 14-30 mm | 1/2-20 | 1/4 in |
| 32-60 mm | 5/8-18 | 1/4 in |
| 68 mm and up | 5/8-18 heavy duty | 1/4 in, sometimes 5/16 in |
Two checks before you buy: the thread on the saw, and whether the arbor has a collar stop. A hex shank arbor that fits a 10 mm chuck will not fit a 3/8 in chuck.
