- Metal
- Sheet metal
- Thin metal
A fine-tooth metal jigsaw blade sized for sheet and thin stock, not thick plate.
Pros
- Fine 17-24 TPI keeps at least three teeth on thin stock so it will not snag or strip
- HSS wavy-set teeth handle both ferrous and non-ferrous sheet metal
- T-shank universal fit and low pack price make it easy to keep spares on hand
Cons
- Fine pitch is far too slow and clogs badly in wood
- Rated only for metal under about 1/8 in, so it stalls in thick plate
- HSS teeth overheat and dull fast without cutting oil on longer runs
