Demolition Cobalt Wood & Non-Ferrous Metal Reciprocating Saw Blade – 225mm 6 TPI – Pack of 3

When you need a 225mm cobalt wood reciprocating saw blade that can take a hammering on site and keep going, this is where you start looking. These M42 bi-metal blades are made with 8% cobalt HSS and built specifically for demolition and rescue applications, the kind of work that destroys cheap blades inside a minute. Nailed timber, aluminium sections, particle board, plasterboard, soft and hardwood, these cut through it all without the blade binding, bending, or making you regret your life choices.

The 6 TPI configuration is a deliberate choice for demolition work. Fewer teeth means faster, more aggressive material removal rather than the clean finish you’d want on a fitted kitchen. At 225mm in length with an extra wide 22mm body and 1.5mm thickness, there’s real stability here. Thin blades flex under load and that flex is what breaks teeth or jams in the cut. The added width and thickness keep the blade tracking properly even when you’re cutting at an awkward angle through a stud wall full of surprises.

Where These Cobalt Reciprocating Saw Blades Earn Their Keep

Demolition and strip-out work is the obvious application, but these also perform well anywhere a standard blade would be used and you just want it to last longer under harder conditions. The special geometry milled HSS cutting teeth are designed to deal with the inconsistency of real-world demolition material, old hardened timber, mixed substrates, the odd hidden fixing. The cobalt content in M42 bi-metal raises the heat resistance of the teeth considerably, which matters when you’re pushing a recip saw hard for extended periods.

Universal Fitting

The universal shank fits the vast majority of reciprocating saws on the market, so there’s no compatibility headache. These are comparable to the well-known Bosch S1110DF, which gives you a useful reference point if you’re used to that blade. Sold in a pack of three, which is a sensible quantity for demolition work where you might go through more than one blade on a bigger job.
