Jigsaw Blades – Metal Cutting – HSS Blades – T118A

The T118A HSS metal jigsaw blades are a go-to choice for anyone cutting thin sheet metals on site or in the workshop. High Speed Steel holds its hardness at elevated temperatures, which matters when you’re pushing through mild steel or stainless — both materials that generate serious heat and will destroy a standard bi-metal blade faster than you’d expect. These are built for that kind of work.

The 76mm blade length suits most standard jigsaws and gives enough travel for clean through-cuts on sheet material without flexing under load. Milled and wavy set teeth — MWS, as it’s printed on most blade packaging — produce a fine, straight cut with minimal burring. Less time on the grinder cleaning up edges afterwards, which is always welcome.

Where T118A HSS Jigsaw Blades Earn Their Keep

Sheet metal work is the obvious application, but these blades are equally useful when you’re cutting stainless steel sheet for kitchen fit-outs, electrical enclosures, or HVAC ducting. The wavy set keeps the blade tracking straight, which is harder to achieve with metal than most people realise until they’ve watched a blade wander off line mid-cut. Mild steel up to a few millimetres thick is well within range, and the HSS body means the blade won’t anneal (soften from heat) the way carbon steel does under sustained cutting.

Fitting is straightforward — the T-shank fits the vast majority of modern jigsaws, so there’s no adapter faff. Set your jigsaw speed appropriately for metal: slower than you’d use for timber, and let the blade do the work rather than forcing it through. A drop of cutting fluid or even a smear of oil on the cut line will extend blade life noticeably if you’re doing any volume of work.

Sold in packs of five, these t118a hss metal jigsaw blades are priced sensibly enough to keep a few sets in the van without it hurting the job margin. A spare set on hand is far less painful than stopping mid-job to chase blades down.
