Jigsaw Blades – Metal Cutting – HSS Blades – T318A

The T318A HSS metal jigsaw blades are built for one job: cutting metal without making a mess of it. High Speed Steel construction means the blade holds its hardness even as heat builds up during the cut, which matters more than people realise when you’re working through mild steel or similar materials that generate a fair amount of friction. These are not the blades you reach for when trimming a bit of MDF. These are the ones you grab when there’s steel in the way.

Each blade runs at 132mm and uses a milled and wavy set tooth pattern, commonly referred to as MWS. That tooth geometry does two things well: it reduces vibration, and it produces a noticeably finer cut edge than a standard coarse blade. If you’ve ever tried to cut thin sheet metal with the wrong blade and ended up with a ragged, chattering mess, the difference here is immediate. The cut is controlled, straight, and clean enough that you’re not spending the next ten minutes filing down a rough edge.

Where T318A HSS Jigsaw Blades Get Used

These blades cover a solid range of metalwork applications. Sheet metal fabrication, cutting steel pipe to length, trimming aluminium sections and profiles, working with copper, brass and other non-ferrous stock — the HSS body handles them all without losing its edge prematurely. The wavy tooth set is particularly effective on thinner gauges where a coarser pattern would catch and snag.

Why HSS Makes a Difference on Metal

Bi-metal blades are popular for general-purpose use, but a dedicated HSS blade has a harder body throughout, which makes it better suited to sustained metal cutting where temperatures stay elevated. The blade resists heat-related softening, so it keeps cutting accurately for longer on the kind of work it was designed for. For tradespeople regularly cutting metal on site, having the right blade in the kit saves time and reduces wasted cuts. The T318A comes in a pack of five, so you’re not scrambling for a replacement mid-job.
