Freud DS0332BF5 Hvac Bi-metal Recip Blade 3-1/4in 32TPI 5pk

Product Description

The FREUD DS0332BF5 is a 5-pack of 3-1/4 inch bi-metal reciprocating saw blades engineered specifically for HVAC and ductwork cutting applications. Each blade runs 32 teeth per inch (TPI), optimizing them for fast, clean cuts through thin sheet metal, duct panels, and similar light-gauge materials. The bi-metal construction pairs a hardened cutting edge with a flexible body to resist breakage during aggressive cuts. A Perma-SHIELD non-stick coating reduces friction and prevents gumming when cutting metal, extending blade service life. HVAC technicians and sheet metal trades reach for this blade when working in tight spaces where a compact profile is essential.

These blades are designed for residential and commercial HVAC service and installation work, including ductwork fabrication, register openings, and thin-metal demolition. The fast puncture tip allows the blade to self-start in sheet metal without pre-drilling a pilot hole, reducing setup time on the job. The small gullet, high-tooth-count geometry limits vibration and chatter, which matters when cutting installed ductwork in occupied spaces. The 5-pack format suits contractors who run high blade volume on HVAC service calls or new installations.

Key Features

• 32 TPI bi-metal blade optimized for thin sheet metal and HVAC ductwork
• Fast puncture tip enables direct plunge cuts without a pilot hole
• Compact 3-1/4 inch blade body for access in tight HVAC cavities
• Perma-SHIELD non-stick coating reduces friction and prevents gumming
• Ultra-hardened cutting edge for extended blade life in metal cutting
• Small gullets minimize vibration and chatter during thin-metal cuts

Compatibility

Designed as a universal-shank reciprocating saw blade compatible with standard reciprocating saws accepting universal T-shank or similar bi-metal blade shanks. Intended for thin metal, sheet metal, HVAC ductwork, and light-gauge metal cutting applications.

Installation Notes

Installation of HVAC ductwork and sheet metal components is typically performed by licensed HVAC technicians or sheet metal workers. Always power down and lock out the reciprocating saw before changing blades. Wear cut-resistant gloves and eye protection when handling and operating saw blades on sheet metal. Follow applicable SMACNA and local mechanical code guidelines for ductwork modifications.
