Milwaukee 48-42-2120 2-3/4" 18TPI Bi-Metal U-Shank Jig Saw Blades, 5-Pack

The Milwaukee 48-42-2120 Jig Saw Blades are purpose-built for clean, efficient metal cutting on the jobsite or in the shop. Each blade measures 2-3/4" in length and features an 18TPI tooth pattern designed specifically for metal cutting applications, paired with a universal U-Shank profile for broad compatibility with jig saws that accept U-Shank blades. The blades are made from bi-metal construction, combining a flexible backing with hardened cutting edges for longer blade life when working through metal stock such as conduit, brackets, and enclosure panels. Sold in a 5-pack, these blades give electricians, HVAC technicians, fabricators, and maintenance crews a ready supply of replacement blades for ongoing metal-cutting tasks without a mid-job trip to the supply house.

Key Features

• Blade Length: 2-3/4" overall length sized for standard jig saws accepting U-Shank blades.
• Tooth Pattern: 18TPI (teeth per inch) configuration engineered for controlled, efficient metal cutting.
• Durable Construction: Bi-Metal blade material provides flexibility along with wear and heat resistance for extended cutting life in metal.
• Shank Type: U-Shank design allows quick, secure blade changes and fits a wide range of jig saws.
• Application: Purpose-designed for metal cutting rather than wood or general-purpose materials.
• Versatile Fit: Universal U-Shank profile makes these blades compatible with most jig saws that accept U-Shank style blades, reducing the need to stock multiple blade types.
• Pack Quantity: Sold as a 5-pack so electricians and fabricators always have spare blades on hand for continued cutting work.
