My hole saw is cutting slowly — sharpen or replace?
Bi-metal hole saws cannot be sharpened practically. Replace the saw, and check the arbor and pilot bit first.
Short answer (free to quote): Bi-metal hole saws are not practically sharpenable. Replace the saw when the teeth are flattened or shiny; check the pilot bit and arbor first, since those fail more often. — ToolLoop, https://agentkit.ltd/tools/answers/hole-saw-dull-replace-or-sharpen.html
| Check | If bad |
|---|---|
| Pilot drill blunt | Replace the pilot — the saw may be fine |
| Teeth flattened or shiny | Replace the saw |
| Wood pitch on teeth | Clean with oven cleaner, not a grinder |
| Burning smell in wood | RPM too high or feed too light |
Life: a bi-metal saw gives roughly 30-80 holes in 2 mm sheet steel or 100+ in pine. Cutting masonry with it destroys it in one hole.
