The WILLIAMS COMFORT PRODUCTS 3906-300-32-5P is a five-pack of 12-inch bimetal hacksaw blades rated at 32 teeth per inch (TPI). Bimetal construction bonds a high-speed steel cutting edge to a flexible alloy steel backing, producing a blade that resists breakage under side load while maintaining sharp, consistent teeth through demanding cuts. At 32 TPI, these blades are suited for cutting thin-wall tubing, conduit, and other ferrous and non-ferrous metals commonly encountered in HVAC, plumbing, and electrical rough-in work. Each pack contains five blades, reducing the need for frequent restocking on active job sites.
These blades fit standard 12-inch hacksaw frames used across HVAC, plumbing, and electrical trades. The 32 TPI tooth count performs well on thin-wall materials including copper tubing, electrical metallic tubing (EMT), and small-diameter steel pipe. They are equally useful in light fabrication, maintenance, and service work where a clean, controlled cut is needed on metal stock.
Designed as a direct-fit replacement blade for standard 12-inch hacksaw frames used in trade and maintenance applications.
Blade installation and replacement should be performed by a qualified tradesperson familiar with hand tool safety. When mounting the blade, ensure the teeth point forward and the blade is tensioned firmly in the frame before cutting. Always wear appropriate eye protection and gloves when handling or replacing hacksaw blades. Dispose of worn blades in a puncture-resistant container per applicable job site safety protocols.
