The DIABLO DS0414BF2 is a 4-inch, 14/18 TPI bi-metal reciprocating saw blade engineered for metal cutting applications. Sold as a 2-pack, this blade features an ultra-hardened cutting edge that delivers up to 4 times longer service life compared to standard blades. A Dual Tooth configuration pairs a double-tooth pattern with small gullets to accelerate material removal while maintaining edge durability. A Perma-SHIELD nonstick coating reduces friction and heat buildup during cuts, while also providing corrosion resistance. Intended for use by metal fabricators, HVAC technicians, plumbers, and electricians performing cut-in or demolition work with a reciprocating saw.
The DS0414BF2 is suited for medium metal cutting tasks including conduit, pipe, tube, sheet metal, and structural steel in residential and light commercial applications. The 14/18 variable TPI pattern allows the blade to transition efficiently between thinner and thicker metal stock without changing blades. The 4-inch cutting length fits standard reciprocating saw chucks and is well-suited to tight-clearance work where maneuverability is limited.
Designed as an OEM-style replacement or upgrade blade for standard reciprocating saws accepting universal shank bi-metal blades in metal cutting applications.
Installation and blade changes should be performed by a qualified tradesperson with the reciprocating saw unplugged or the battery pack removed before servicing the chuck. Confirm the blade shank seats fully and the chuck lock is engaged before powering the tool. Eye protection and appropriate gloves are required when handling and cutting with metal-cutting blades. Dispose of worn blades in accordance with local sharp-waste disposal guidelines.
