Dewalt DW3774-5 Jig Saw Blade 18 Tpi Cobalt 5-pack

Product Description

The DEWALT DW3774-5 is a cobalt jig saw blade designed for cutting medium-gauge metal. Each blade measures 3 inches in length with an 18 teeth-per-inch (TPI) configuration, making it suited for controlled, clean cuts through ferrous and non-ferrous metals encountered in trade work. The cobalt construction provides added hardness and heat resistance compared to standard bi-metal blades, extending blade life in demanding cutting applications. This package includes 5 blades, making it a practical supply for shop stocking or field kits. Installation and use require a compatible jig saw with a standard blade mount.

These blades are used in commercial and residential settings wherever metal fabrication, conduit work, sheet metal trimming, or structural cutting is performed. Electricians, HVAC technicians, plumbers, and general contractors commonly use 18 TPI metal-cutting blades for tasks such as cutting electrical enclosures, HVAC ductwork components, strut channel, and thin-wall pipe. The 3-inch blade length fits compact and full-size jig saws used in tight-access installations.

Key Features

• 18 TPI tooth configuration optimized for medium metal cutting
• Cobalt blade material provides increased hardness and heat resistance
• 3-inch blade length suited for controlled cuts in confined spaces

Installation Notes

Blade changes should be performed with the jig saw unplugged or the battery removed before handling. Use appropriate personal protective equipment including eye protection and gloves when cutting metal. Secure the workpiece firmly before beginning a cut to prevent blade binding or breakage. Follow the tool manufacturer guidelines for blade insertion and locking mechanism engagement.
