This 32 TPI (teeth per inch) shatterproof hacksaw blade set is designed for fine, precise cutting of thin metal sheets, tubing, plastics, and other thin-walled materials. The high tooth density (32 TPI) produces smoother cuts with minimal burrs — ideal when you need a clean, accurate finish or are cutting thin or delicate stock. The “shatterproof” build (often via heat treatment or flexible steel backing) increases durability and reduces the risk of blade breakage under tension or during awkward cuts — making it safer and more reliable for professional workshop use or DIY tasks. Supplied as a set of two blades, it gives you spares or dual‑blade capability for extended work.
