Irwin 372 Series 9-Inch Bi-Metal Reciprocating Saw Blade, 6 TPI

The Irwin 372 Series 9-Inch Bi-Metal Reciprocating Saw Blade is engineered for roughing-in work and cutting through nail-embedded wood on demolition and remodeling jobsites, available as model 372156 and model 372956. This 6 TPI blade combines bi-metal construction with an electronic beam weld for stronger, longer-lasting teeth that resist breakage under repeated impact. An 8% cobalt content keeps the cutting edge sharp longer, even when the blade encounters embedded fasteners. Rated for use on materials 3/16 inch (5 mm) and thicker, this reciprocating saw blade delivers dependable performance for professional contractors on every cut.

  • Precision Tooth Design: 6 TPI precision-set teeth produce faster, smoother cuts through wood and embedded fasteners.
  • Reinforced Tooth Weld: Electronic beam weld construction creates stronger, longer-lasting teeth that hold up to repeated impact.
  • Cobalt-Enhanced Edge: 8% cobalt content keeps teeth sharp longer, extending blade life on tough roughing-in work.

Irwin 372956 – Frequently Asked Questions

1) Will a 6 TPI Irwin 372 Series blade cut nail-embedded wood without stripping teeth?
That is exactly the job it's built for. The 372 Series bi-metal blade uses an electronic beam weld at the tooth line so the teeth hold up to repeated impact against embedded fasteners, and 8% cobalt in the cutting edge keeps it sharp longer than a plain carbon steel blade. At 6 TPI the gullets are coarse enough to clear wood chips fast on demo and roughing-in cuts, which is where you hit hidden nails.
2) What is the minimum material thickness for the Irwin 372 Series reciprocating blade?
3/16 inch (5 mm) and thicker. On anything thinner than that the 6 TPI tooth spacing lets the stock skip between teeth instead of being cut, so sheet metal, thin tube, or thin panel work calls for a finer-pitch blade rather than this one.
3) Is 6 TPI the right tooth count for framing lumber, or should I go finer?
For framing lumber, joists, studs, and general wood demolition, 6 TPI is the coarse end and that is what you want - it cuts fast and clears chips. Finer pitches cut slower in wood and load up. Go finer only when the material drops below 3/16 inch thick, which is the minimum this blade is rated for.
4) What is the difference between Irwin 372156 and 372956?
Both are 372 Series bi-metal 6 TPI blades with the same electronic beam weld and 8% cobalt edge; the part numbers differ by blade length option. Order by the length your saw and cut depth call for - the cutting specification is identical between the two.
5) Is a bi-metal blade worth it over a carbon steel demo blade?
In nail-embedded wood, yes. Carbon steel teeth dull or shear on contact with a fastener; the 372 Series bi-metal body gives a hard high-speed tooth on a flexible backer, so it cuts faster and survives the hit. The 8% cobalt content in the edge is what extends life through repeated fastener strikes. For clean, nail-free lumber a carbon blade will do the job cheaper.
6) Is the Irwin 372156 sold as a single blade or a multi-pack?
The 372156 ships as a set rather than a single loose blade, which is how most contractors buy a consumable demo blade. Country of origin is the United States.
