Starrett 3X Power bi-metal reciprocating blades in 150mm, 10-14tpi. Built for heavy demolition and emergency extrication. Thicker body, super aggressive tooth pitch, up to three times the blade life. Pack of 5.
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.
Pro Tip: On demolition cuts through nail-embedded timber, keep your shoe plate pressed firmly against the material and let the blade do the work at full stroke rather than forcing the tool forward, this reduces blade wander and extends edge life considerably.
These blades are used across demolition, strip-out and emergency extrication work. Roofers use them on battens and sheathing boards when old fixings are still present. Builders rely on them for cutting through stud partitions, door frames and floor sections where nails, screws or hidden fixings are almost guaranteed. Emergency services and access teams carry reciprocating saw blades at this spec precisely because of the mixed-material performance.
They also work well on light structural steel, box sections, conduit and copper pipe, making them a practical all-rounder when you do not want to be swapping blades mid-job.

Not suitable for: Not suitable for clean, precision cuts on finished timber or sheet materials where a smooth edge is required. The aggressive tooth pitch is designed for material removal, not fine joinery work.
Fit the blade into the chuck with the tool unpowered and the lock engaged. Check the shank is fully seated before releasing. For demolition cuts through timber with embedded fixings, keep the shoe plate pressed against the material surface and use full stroke length at a steady pace rather than forcing the tool into the cut.
On steel or pipe, let the blade speed do the work. Applying too much forward pressure overheats the teeth and shortens blade life. A small amount of cutting fluid on metal will help, though on a busy demolition job most people skip it and accept slightly reduced blade life in exchange for pace.
Ensure the reciprocating saw is switched off and the battery removed or power disconnected before fitting the blade
Insert the blade shank fully into the chuck until it locks positively in place
Reconnect power and select an appropriate speed setting for the material
Press the shoe plate firmly against the workpiece before starting the cut to reduce vibration and blade wander
Begin cutting at full stroke length and a consistent forward pace, avoiding excessive downward pressure
On nail-embedded timber, maintain steady contact and expect some resistance as the blade passes through fixings
For metal cutting, reduce forward pressure and allow the tooth speed to do the work
Check the blade periodically for signs of tooth wear or cracking, particularly after heavy use on mixed materials
Will these blades fit my existing reciprocating saw?
Yes, in almost all cases. The 3X Power King Cut blades use a standard universal shank compatible with all major brands including DeWalt, Makita, Milwaukee, Bosch and Hilti. If your saw accepts standard reciprocating saw blades, these will fit.
What is the difference between the 3X Power range and standard bi-metal blades?
Starrett's 3X Power blades feature a thicker blade body and an updated bi-metal formulation that Starrett rate at up to three times the service life of their previous line. The King Cut design also uses a variable tooth pitch to reduce vibration, which matters on long demolition sessions. Standard bi-metal blades will cut, but they tend to fatigue and snap more quickly on heavy demolition work with embedded fixings.
The Starrett 3X Power King Cut blades are bi-metal construction, combining a high-speed steel tooth edge with a flexible alloy steel body. The 0.89mm blade thickness and 19mm width give improved resistance to lateral flex compared to thinner demolition blades. Variable 10-14tpi tooth pitch reduces harmonic vibration during cutting. The 152mm blade length suits a wide range of reciprocating saw stroke configurations.
