Starrett 68718 Bi-metal Jigsaw Blade 6 Tpi U-shank 5-pack

Product Description

The STARRETT 68718 is a bi-metal jigsaw blade engineered for demanding cutting applications where blade durability and consistent tooth performance matter. At 4 inches in length and 5/16 inches wide with a 0.05-inch thickness, this blade is built to handle a range of materials without premature fatigue or tooth stripout. It features a U-shank mount and a toothed cutting edge with an alternate tooth set at 6 teeth per inch (TPI), making it well-suited for aggressive, fast cuts through wood and similar materials. Sold in a pack of 5, it is a practical stocking choice for tradespeople who run through blades regularly on the job.

This blade is appropriate for residential and light commercial cutting tasks where a U-shank jigsaw is in use. The 6 TPI configuration favors faster, coarser cuts over fine finish work, making it a good fit for rough framing cuts, general carpentry, and material removal. The bi-metal construction combines a high-speed steel tooth edge with a flexible alloy steel body, reducing the risk of blade breakage during aggressive or curved cuts. This product is not rated for contour cutting applications.

Compatibility

Designed for use with U-shank jigsaws. Verify your tool accepts U-shank blades before installation, as U-shank and T-shank mounts are not interchangeable.

Installation Notes

Blade installation and replacement should be performed by a qualified user with the jigsaw unplugged or the battery pack removed. Confirm the blade is fully seated and the retention mechanism is secured before operating the tool. Wear appropriate eye and hand protection when handling or changing jigsaw blades, as tooth edges are sharp.
