Irwin 372156BB Reciprocating Blade 12 Inches 6 Tpi

Product Description

The IRWIN 372156BB is a 12-inch, 6 TPI bi-metal reciprocating saw blade engineered for nail-embedded wood cutting and roughing-in applications. The blade is built with bi-metal construction that combines flexibility with cutting durability, and the teeth are alloyed with 8% cobalt to maintain sharpness through repeated contact with fasteners and dense lumber. Precision-set teeth produce faster, smoother cuts with less blade deflection. Licensed electricians, plumbers, and general contractors rely on this blade for demolition and rough-in work where hidden nails and screws are common hazards for standard blades.

This blade is suited for residential and light commercial demolition, framing teardown, and mechanical rough-in tasks where wood materials containing embedded nails must be cut efficiently. It is rated for use with materials 3/16 inches and thicker, making it appropriate for dimensional lumber, sheathing, and similar substrates. Trades that regularly perform cut-ins for pipe, conduit, or duct penetrations through framed walls will find this blade a practical choice for day-to-day site work.

Key Features

• Bi-metal construction for durability and resistance to blade fatigue during demanding cuts
• 8% cobalt tooth alloy maintains edge sharpness through nail-embedded material
• Precision-set teeth deliver faster, smoother cutting action
• 12-inch blade length provides reach for deep or angled cuts in framing
• Rated for materials 3/16 inches and thicker
• 6 TPI tooth pattern optimized for aggressive wood removal

Compatibility

Designed as a universal-shank reciprocating saw blade compatible with standard reciprocating saws that accept universal T-shank or standard straight-shank blade mounts, for use in nail-embedded wood cutting applications.

Installation Notes

Installation of this blade should be performed by a qualified trade professional following the saw manufacturer's blade-change procedure with the tool powered off and unplugged or battery removed. Wear appropriate eye and hand protection when cutting nail-embedded material, as blade contact with fasteners can eject debris. Inspect the blade for cracks or missing teeth before each use and replace immediately if damage is found.
