Bosch U118A3 20 Tpi Jigsaw Blade 3 Pack Universal Shank

Product Description

The ROBERT BOSCH TOOL GROUP U118A3 is a 3-pack of high-carbide steel jigsaw blades engineered for straight cuts in ferrous and nonferrous metals. Each blade features a Universal shank for broad tool compatibility and a 20 teeth-per-inch (TPI) tooth pattern optimized for clean, controlled cuts through sheet metal and thin stock. High-carbide steel construction extends blade life compared to standard bi-metal or carbon-steel blades when working through harder metals. These blades are installed and used by electricians, HVAC technicians, plumbers, fabricators, and general tradespeople who need reliable metal-cutting performance from a jigsaw.

The U118A3 blades are designed for straight-cut applications in ferrous and nonferrous metals including sheet metal in the 10 to 16 gauge range and thin metals from 1/16 inch to 1/8 inch thick. Typical use cases include cutting conduit knockouts, sheet metal ductwork panels, thin steel plate, aluminum sheet, and copper stock. The 20 TPI configuration keeps teeth engaged through thin cross-sections, reducing blade chatter and burring on exit cuts. This 3-pack format suits contractors and service techs who keep spares on hand for ongoing metal fabrication or service work.

Installation Notes

Blade installation and changes should always be performed with the jigsaw unplugged or the battery removed. Ensure the blade is fully seated and the blade clamp is secured before powering the tool. Eye protection and cut-resistant gloves are recommended when handling metal-cutting blades and cut workpieces. Secure the workpiece firmly before cutting to prevent vibration and blade deflection.
