Starrett bu46 Bi-metal Jig Saw Blade 5 Inches 6 Tpi

Product Description

The STARRETT bu46 is a bi-metal jig saw blade built for cutting steel, non-ferrous metals, cast iron, plastics, and wood. It measures 5 inches in total length and runs at 6 teeth per inch, making it a versatile choice for mixed-material cutting tasks. The blade features a patent-pending unified shank design that fits both universal shank and Bosch shank jig saws, eliminating the need to stock separate blades for different tool brands. At 0.050 inches thick and 3/8 inches wide, the bu46 is dimensionally suited to standard residential and light commercial cutting applications. Licensed electricians, plumbers, HVAC techs, and general trade professionals commonly reach for jig saw blades like this during rough-in and service work.

The bu46 is used across a wide range of cutting scenarios where a single blade must handle multiple workpiece materials. It is well suited for cutting steel pipe and sheet metal, non-ferrous stock, cast iron fittings, plastic conduit or pipe, and wood. The alternate tooth form delivers a clean, controlled cut across these material types. Tradespeople who frequently switch between material types on a single job site will find the unified shank compatibility especially practical, as one blade fits the most common jig saw platforms without adapter hardware.

Installation Notes

Blade replacement should be performed with the jig saw unplugged or the battery pack removed before handling the blade.
