The Bosch PRO T321AF is a bi-metal jigsaw blade designed specifically for cutting metal pipes, profiles, and thin sheet metal with walls between 1 mm and 3 mm thick. Constructed with a hardened high-speed steel (HSS) tooth strip bonded to a high-carbon steel (HCS) body, the blade combines the hardness needed to cut metal effectively with the flexibility required to resist snapping under load. This bi-metal construction contributes to a longer service life compared to standard single-material blades. The blade's tapered body and thin kerf reduce friction through the cut, while the milled, wavy-set teeth at 21 TPI deliver smooth, controlled cutting progress. Its extended 132 mm length allows it to reach around pipes and profiles up to 65 mm in diameter, making it well suited for plumbers and fabricators cutting copper, steel, or aluminium pipework. The T-shank fitting ensures compatibility with all T-shank jigsaws, so it's ready to use straight from the pack with most professional and trade-grade machines.
