Starrett 68721 Bi-metal Jigsaw Blade 10 Tpi U-shank 5 Pack

Product Description

The STARRETT 68721 is a bi-metal jigsaw blade designed for cutting a wide range of materials in professional trade and maintenance applications. Measuring 4 inches in length and 5/16 inches (0.3125 inches) in width, the blade features a ground taper tooth set at 10 teeth per inch (TPI) for controlled, consistent cuts. At 0.05 inches thick, this blade offers the rigidity needed for straight-line work while remaining suitable for moderate curve cuts. The U-shank interface provides a secure, tool-free blade change on compatible jigsaw models. Each order ships as a pack of 5 blades.

This blade is suited for electricians, plumbers, HVAC technicians, and general contractors who need a reliable cutting blade on the job. The 10 TPI tooth configuration is well matched to cutting wood, plastics, and thin-gauge metals commonly encountered in mechanical and electrical rough-in work. The toothed cutting edge and ground taper set deliver clean entry cuts and extended blade life in both residential and light commercial service environments.

Installation Notes

Blade installation and removal should be performed with the tool unplugged or the battery removed. U-shank blades seat into the blade clamp without tools on most compatible jigsaws — confirm the blade is fully seated and locked before operating. Inspect the blade for cracks or worn teeth before each use and replace as needed. Dispose of worn blades in a puncture-resistant container per shop safety practices.
