Starrett 68720 Bi-metal Jigsaw Blade 8 Tpi U-shank 5 Pack

Product Description

The STARRETT 68720 is a bi-metal jigsaw blade designed for demanding cutting applications where durability and consistent tooth performance are required. At 4 inches in length and 5/16 inches wide with a 0.05-inch blade thickness, this blade fits U-shank jigsaws and delivers a toothed cutting edge with an alternate tooth set at 8 teeth per inch (TPI). The bi-metal construction combines a high-speed steel tooth edge with a flexible alloy steel body, resisting breakage under load while maintaining a sharp cutting edge through extended use. This blade is sold in packs of 5. It is suited for electricians, plumbers, HVAC technicians, and general tradespeople who rely on jigsaws for rough cuts in wood, plastic, and similar materials.

The STARRETT 68720 is appropriate for residential and light commercial job-site use wherever a U-shank jigsaw is the tool of choice. The 8 TPI count makes it well suited for general-purpose cuts in softwood, hardwood, and plastics where a balance between cut speed and surface finish is needed. At 4 inches in blade length, it handles typical material thicknesses encountered in trade work. Contour cutting is not the intended application for this blade geometry.

Installation Notes

Blade changes should be performed with the jigsaw unplugged or the battery removed. Follow the jigsaw manufacturer's procedure for U-shank blade insertion and ensure the blade is fully seated and locked before operation. Wear cut-resistant gloves when handling jigsaw blades. Inspect blades before each use and replace any blade showing cracks, missing teeth, or visible deformation.
