Jigsaw Blades – Metal Cutting – HSS Blades – T218A

The T218A HSS metal jigsaw blades are designed for cutting thin sheet metals where a standard wood blade would last approximately five minutes before turning into a very expensive nail file. High Speed Steel holds its hardness at elevated temperatures, which matters because cutting metal generates real heat at the blade tip. These blades keep their edge where bi-metal alternatives can sometimes feel like overkill for lighter gauge work.

The 76mm blade length suits most standard jigsaws and the T-shank fitting makes them compatible with the vast majority of modern machines on the market. Milled and wavy set (MWS) teeth are the detail that actually defines the cut quality here. Wavy set teeth reduce the aggressive bite per tooth, spreading the cutting load across more points of contact. That gives you a fine, controlled cut rather than the kind of jagged edge that needs half an hour of filing before it looks presentable.

Where T218A HSS Jigsaw Blades Perform Best

These blades are well suited to sheet steel, mild steel plate, and similar ferrous metals in the thinner gauges. The fine tooth configuration means you are not going to be ripping through anything particularly thick, which is exactly what they are designed for. Precise, clean cuts in material that would otherwise cause problems for a coarser blade.

High Speed Steel as a blade body material has been around long enough that it is not going anywhere. It stays hard under thermal stress in a way that standard carbon steel simply does not, which is the whole point when you are grinding metal with a reciprocating blade at speed. Sold in packs of five, so you have enough to get through a decent run of work without needing to stop and reorder halfway through a job. For anyone regularly cutting sheet metal on site or in the workshop, keeping a pack of T218A HSS metal jigsaw blades in the toolbox is just sensible preparation.
