Designed for materials 1/8" to 7/8" thick, each 4" blade features 18 teeth per inch, a wavy set, straight cut style, and a unified shank compatible with most jig saws. Perfect for professionals seeking efficiency and durability in metal or wood cutting applications.

• Superior Quality - Starrett is known for high-quality, durable tools. The unified shank blades are likely to provide excellent cutting performance and longevity.
