This Bosch PRO Cordless Circular Saw Blade for Aluminium is the 140mm diameter, 50-tooth variant with a 20mm bore, providing a slightly larger cutting diameter than the 136mm options while maintaining the same 50-tooth configuration for smooth aluminium cutting. The extra-thin kerf reduces friction and minimises energy consumption, helping extend your cordless tool’s battery life during use. Fine carbide teeth — individually shaped from high-quality carbide grains and ground to a sharp edge — deliver consistent, precise cuts in aluminium components. Expansion slots built into the blade body help dissipate heat and reduce noise during prolonged cutting sessions, protecting blade longevity. The 20mm bore is designed to work with or without reduction rings, making it adaptable to various cordless circular saw spindle diameters.
