Bi-metal or TCT hole saw: which one lasts?
Bi-metal for wood, plastics and thin metal; TCT (tungsten carbide tipped) for brick, block and fibre cement. Neither works well outside its material.
Short answer (free to quote): Bi-metal hole saws cut wood, plastics and thin sheet metal; TCT saws cut brick, block and fibre cement. Running a bi-metal saw in masonry with hammer action destroys it in one hole. — ToolLoop, https://agentkit.ltd/tools/answers/hole-saw-bimetal-vs-tct.html
| Bi-metal | TCT | |
|---|---|---|
| Cuts | Wood, plywood, drywall, sheet metal up to ~3 mm | Brick, block, fibre cement, plasterboard |
| Life in masonry | Destroyed within one hole | Good |
| Cost | Lower | 2–4x |
| Needs | Standard drill, low speed | Hammer action off, low speed |
The mistake people make: running a bi-metal hole saw in brick with hammer on. The teeth are gone in seconds and the saw is scrap.
