Reciprocating Saw Blades – Metal Cutting – Bi-Metal – S922EF

The S922EF bi-metal reciprocating saw blade is designed specifically for cutting sheet metal, bringing together two materials that each do something the other can’t. The body is high carbon steel, which gives the blade the flex it needs to survive the punishment of a reciprocating saw without snapping mid-cut. The cutting edge is high speed steel, which holds its sharpness far longer than a standard HCS blade would under the same conditions. Together, they make a blade that keeps working long after a cheaper alternative would have given up.

Milled and wavy set teeth, known in the trade as MWS, are what give this blade its clean, straight cut through sheet metals. The wavy set staggers the tooth profile slightly, which reduces vibration and burring at the cut edge. Less burring means less time spent cleaning up after the cut. On a job where you’re making a lot of cuts, that adds up quickly.

Where S922EF Bi-Metal Reciprocating Saw Blades Fit In

These blades come into their own on any site where sheet metal needs cutting quickly and cleanly without swapping to a grinder or tin snips. Ductwork, steel cladding, metal studding, box sections, and general fabrication work are all well within their range. The 225mm blade length gives you enough reach to work through thicker profiles and into tight corners that shorter blades can’t reach comfortably.

Bi-metal construction also means the blade won’t become brittle in cold conditions, which matters if you’re working outside in winter or in an unheated warehouse. The combination of flexibility and edge retention holds up well across a wide temperature range, which is one of the main reasons professionals prefer bi-metal over single-material blades for metal cutting.

Extended service life is probably the most practical argument for spending a little more per blade. A blade that lasts three times as long as a budget alternative costs less overall, and you spend less time stopping to change blades on the job. These come in a pack of 5, which keeps you stocked up without having to order constantly.
