Makita jig saw blade A-85743, bayonet type No. B-23, for cutting thick metal. Bayonet shank, fitting Makita jig saws and other saws taking a T-shank blade.
What it is for
Cutting steel plate, heavy sheet and section with a jig saw. The tooth pitch is fine and closely spaced, which is what metal demands — a coarse wood blade put into steel will lose its teeth within seconds.
Cutting metal with a jig saw
- Keep at least three teeth in contact with the material at all times. That rule decides which blade you need more than anything else.
- Run the saw slowly and switch the orbital action off. Orbital action is for wood; in metal it just batters the teeth.
- Clamp the work. Sheet metal that vibrates will shred a blade and leave a ragged edge.
- A little cutting fluid along the line extends blade life noticeably.
- Expect a burr on the underside and allow time to dress it.
