The IRWIN 372156 is a reciprocating saw blade designed for demanding cutting applications in construction, demolition, and renovation work. At 12 inches in length with a 6 TPI (teeth per inch) tooth configuration, this blade is built for aggressive, fast cuts through dimensional lumber, timber, and similar materials. The lower TPI count delivers rapid material removal, making it well suited for rough-cut work where cut quality is secondary to speed and productivity. Licensed trades and skilled tradespeople rely on this blade profile for framing teardowns, structural demo, and rough carpentry tasks.
This blade is intended for use with standard reciprocating saws in residential and light commercial construction environments. Its 12-inch blade length provides the reach needed to cut through thick stock, wall assemblies, or stacked material without repositioning. It is sold individually and fits the universal shank style common to most reciprocating saw platforms used in the trades.
Designed as an OEM-style replacement and standard-use blade for reciprocating saws accepting universal shank blades.
Reciprocating saw blade changes should be performed by a qualified carpenter, electrician, or general tradesperson following the tool manufacturer's blade-change procedure. Always power down and unplug or battery-disconnect the reciprocating saw before removing or installing a blade. Ensure the blade clamp or chuck mechanism is fully seated and locked before resuming operation. Eye protection is required during all cutting operations.
