Starrett Bi-Metal Unique Safe-Flex Hacksaw Blades 300mm 18 TPI Pack 2 STRKBS12182

These are bi-metal hacksaw blades designed for cutting tough materials with a focus on durability and efficiency. Featuring Safe-Flex technology, the blades are highly flexible, capable of withstanding bending and, in some cases, knot-like flexibility. The blades are welded with a high-speed steel cutting edge to a resilient alloy steel back, providing improved wear resistance and reduced breakage. Each pack includes two 300 mm (12 in) blades with 18 teeth per inch, suitable for heavy-duty cutting tasks across metals and other tough materials. The blades are designed for use in standard hacksaw frames and are intended to deliver faster cuts and longer blade life, even under demanding conditions such as interrupted cuts or high-stress bending. The product emphasizes shatter resistance and enhanced tooth strength compared to traditional bi-metal blades, making them a robust option for demanding DIY and home improvement projects.
