The GREENLEE 399-24A is a 24 teeth-per-inch (TPI) reciprocating saw blade manufactured from alloy steel. Designed for demanding cutting tasks in trade applications, this blade delivers consistent performance in metal and other materials where fine, controlled cuts are required. The alloy steel construction provides durability through repeated use in the field. It is suited for electricians, plumbers, HVAC technicians, and other trades professionals who rely on reciprocating saws for rough-in and service work.
This blade is used in residential and commercial construction and service environments where a reciprocating saw is the tool of choice for cutting conduit, pipe, straps, or other materials. The 24 TPI tooth count makes it well suited for finer cuts in metal and thinner-walled materials, reducing burring and producing cleaner cut edges compared to lower TPI blades.
Designed as an OEM-style replacement or direct-use blade compatible with standard reciprocating saw tool chucks used across trade applications.
Blade installation and removal should be performed with the tool unplugged or the battery pack removed. Follow the saw manufacturer's blade-change procedure and ensure the blade is fully seated and locked before operating. Always wear appropriate eye protection and gloves when handling saw blades. Blade selection should match the material being cut to avoid blade damage or workpiece damage.
