Milwaukee 5-Piece T-Shank Bi-Metal Jig Saw Blade Set 49-22-1178

ENGINEERED FOR EXTENDED RUNTIME AND SUPERIOR HEAT RESISTANCE

In high-demand professional applications, the mechanical integrity of your cutting edge determines the efficiency of the entire tool. This Milwaukee 5-piece Bi-Metal Jig Saw Blade Set is engineered with a high-speed steel tooth edge electron-beam welded to a flexible carbon steel backing. This bi-metal construction significantly outperforms standard high-carbon steel (HCS) or high-speed steel (HSS) blades by maintaining tooth sharpness under high thermal loads while resisting fracture during aggressive orbital cutting. Manufactured in Switzerland to exacting tolerances, these T-shank blades ensure a secure, zero-play fit in Milwaukee and other leading professional jig saws, maximizing power transfer from the motor to the workpiece for cleaner, faster tracking in both ferrous metals and dense hardwoods.

• / Bi-Metal construction provides up to 10x longer life than carbon steel blades in tough materials.
• / Precision-ground teeth and optimized rake angles deliver faster material removal and reduced vibration.
• / Universal T-Shank design ensures maximum compatibility and high-torque stability in corded and cordless jig saws.
• / Swiss-made manufacturing ensures consistent tooth geometry and blade straightness for professional-grade accuracy.
