Starrett 3X Power Demolition Reciprocating Saw Blades 150mm 10-14tpi Pk5

The Starrett 150mm 10-14tpi demolition saw blade is part of the 3X Power King Cut range, and it does exactly what the name suggests. These are not general-purpose blades squeezed into a demolition box. They are built from the ground up for heavy cutting, with a thicker blade body and an aggressive variable tooth pitch that tears through mixed materials without the blade folding, snapping or losing its edge halfway through a job.

Starrett claim up to three times the life compared to their previous line. Whether you hit exactly that figure depends on what you’re cutting, but in practice these blades hold up noticeably longer than standard bi-metal options on dirty, nail-embedded timber, light steel sections and layered site materials. The thicker body, up to 255Pk wide, resists the sideways flex that kills blades quickly on tight curves or when you’re forcing a cut through dense material.

What Makes the 3X Power King Cut Worth Using on Site

The variable 10-14tpi pitch does two things at once. It keeps the cut aggressive enough for fast material removal, while reducing the harmonic vibration that makes long reciprocating saw sessions genuinely unpleasant. Less chatter means less fatigue, and on a demolition job that can make a real difference by the afternoon. Starrett also describe these as unbreakable, which is bold, but the design prioritises flex resistance and shank integrity, so you are not fishing broken blade sections out of a cavity wall.

The 152 x 19 x 0.89mm format fits standard reciprocating saw chucks across all the major brands. At this length, they work well in moderately confined spaces while still giving enough stroke travel to cut through a 150mm timber section cleanly. Five blades per pack makes the price per blade sensible for trade use, and keeping a few sets on the van is easy enough.

For anyone doing strip-outs, emergency access work, or general demolition where the material is unknown and pace matters, the Starrett 3X Power 150mm 10-14tpi demolition saw blade is a solid, dependable choice.
